🙏If you found this video helpful, please consider sending a couple bucks my way to say thank you by hitting the THANKS button under the video 💲❤. You can't imagine how much I would appreciate it. 🥰
This was a huge help for me. I spent nearly two weeks trying to figure out what was wrong with my Sportster 1200 until I came across this video that explained how far out the screw should be and what possible solutions could be. Great content, Rocco!
How does she idle? Air/fuel screw, how many turns out? Is it a crisp throttle response? Send a pitchure of your motorcycle so I could see the exhaust and intake. To Erocco3964@gmail.com. Start by cleaning air filter, and check oil level. Most time that will be a future. Let us know how that works out.
sometimes with newer bikes you gotta reset your idle by turning your bike to run for 10seconds 4x to reset your idle but thats usually if your bike idles good then gets faster n faster, I would try the carb first before doing that tho
When I removed the plug, I found my screw already adjusted to the "sweet spot" that you recommend, 1 5/8 out. I left it there. I've had no black smoke and my spark plugs were light tan when I changed them with 10K miles on them. The only adjustment I needed to do was replace my stock #42 pilot jet with a #45 one to eliminate the cough on take-off, which I referred to in my comment on your video on replacing jets. Thank you for your excellent videos!
I have a xl1200 that came to me with a arlen ness air filter I was getting a rough idle, and lots of popping in decel. I upped the idle jet from 42 to 45 and drilled out the plug for the idle air mixture screw after watching your videos. The screw was only 1 turn out. I upped it to 2 and added screamin eagle slip ons as well. Runs great now, thanks a million Rocco!
Happy to read all is went well. Thank you for watching and your sub Dan. I'm gonna send you a video on slide needle adjustment. .ruclips.net/video/G1XD0hHtwCw/видео.html. Let us know what you think. Ride safe and have a great day.
I took your advice and replaced my Petcock because the bike was running very rough after 30 minutes of riding. It was idling very fast, then I watched this video and found one of the hose lines was cracking at the bottom of carb. I fixed that and now the 2006 sportster custom is running much better. You saved me a bunch of money and I was able to do it myself. I like learning stuff like this. Again Thank you very much I appreciate your time and advice. Love your video's.
@TWO WHEEL ROCCO, I JUST WANNA SAY THANK YOU FOR GIVING ME THE CONFIDENCE TO DO THESE JOBS ON MY OWN BIKE. I COULDNT HAVE DONE IT WITHOUT YOUR EXPERTISE. YOUR A GREAT TEACHER! IM DISABLED RIGHT NOW AND HAVE NO MONEY BUT WHEN I CAN I SURE WILL SEND YOU SOME . I PROMISE
Happy to help my friend. Thank you for watching and all your support Mickey and all those kind words. Ride safe and have a great day. Have to love those sportsters.
Thanks for the vid. Shout out to you for getting back to everyone in the comments. I read through a lot of them as well as your responses and got some good info. A lot of people post videos and never respond to comments!
Thank you! I've been chasing an issue on my sportster for weeks. After watching this video and making some adjustments I've finally got it running well.
Thanks for the video my bike is rough idleing and carb farting all over the place. This is a great video and explains everything in a very easy to understand way. Keep up the great work.
Another great video, I’ve learn so much on just two of your videos. It has given me confidence to address a tick over problem I may have. Mike Wales UK.
That is great to hear. Any questions just ask. Thank you for watching. Have a great holiday. Ride safe Hope to hear from you soon let us know how it works out.
Happy to help. You should start with the Petcock. the screen and the gas the fuel is the gas tank rusty. Take a look at this video.ruclips.net/video/7Fo9Q93OJXI/видео.html. Thank you for watching and your sub. Let us know how it works out. Ride safe and have a great day.
Thanks for this Rocco! I think my 04 sporty is running rich. New plugs in and the ends are BLACK after 1 run. Rear cylinder is occasionally doing a little misfire whilst running too. Going to adjust the mixture screw and see how it goes from there. Learning loads from your videos mate, thanks a bunch!
Happy to help, remember it's a most important to have a clean air filter. If you run your hand under your air filter and there's oil on your fingertips there's a good chance you have too much oil in the motor. Check the oil dipstick, halfway full is where these motors run their best. Otherwise they will foul your plugs. Too much oil in the motor. This will result in a dirty air filter and a terrible riding bike. I hope this helps. Thank you for watching and your sub drinkster. Ride safe and have a great day. Let us know how it works out.
This is very very helpful. Reading through the comments, i think i may have narrowed down and pinpointed my issue. Plug fouling. I get my fuel mixture and idle just perfect, then 200 miles down the road, she starts backfiring. I pull the plugs and they are dry and black. Im betting its the exhaust. The previous owner slapped some shotgun exhaust on it. My bet is i need to swap out the jets. Whats your opinion with this limited information? Its a 91 883. Fuel mixture is at one and a little over a half turns and the idle is at 900 rpm.
Happy to help. I would test the Petcock first. That's where it all starts. Make sure the peacock holes vacuum. If the diaphragm is failing, that means it won't hold vacuum and it will leak gas and not operate properly which equals a poorly running motor. check the vacuum line from your carburetor to the back of your Petcock or bottom. I will send you the video. Any questions just ask. ruclips.net/video/7Fo9Q93OJXI/видео.htmlsi=MfomcbF3wze-rO5b thank you for watching and all your support Jack.. Let us know how it works out. Ride safe and have a great day.
Great video. I have an 05 883 custom. Idle is great will run all day. But as soon as I turn the gas to take off it backfires through the carb and stalls or almost stalls out and dies. Thinking the carb may need a good cleaning but I'd like to get you're opinion. Thanks and have a good day
I would check your carburetor excelerator pump diaphragm. Remove air filter cover, Twist throttle and look to see if gas squirts gas into your carb. If it does, then check vacuum lines coming off your petcock. Let me know how this works outruclips.net/video/7Fo9Q93OJXI/видео.html Take a look, hope this helps.
My 2005 883 standard did this until I changed my pilot/idle jet from a 42 to a 45. This change also eliminated the "cough" on take off when the engine was the slightest bit cool, regardless of air temperature.
Rocco, bought an 05 Twin 88, stock carb, unknown 2 into 1 with baffle, high flow filter. Was set at 3 turns, plugs look pretty good, a bit sluggish at higher rpm, set at two turns, runs much better but plugs turning a bit to the grey side. But runs great! No backfire, nor did it at 3. Think I should go to 2.5 because of plug color? Couldn’t tell you how jetted. But if it runs good and plugs look good, should I just leave it? One more question. The mixture screw affects the mixture throughout the complete range of throttle, not just idle, doesn’t it? And thank you?
Helps with transition from idle to mid range. but it all adds up in the end. I would leave it at two turns. That tells me the Jets are right size. Hope this helps thank you for your sub Yoso.. Ride safe and have a great day.
hello sir, nice video, I have a 1991 Sportster 1200. I’m stuck on getting the timing down. I replaced the slow jets to a 52. and it still seems like it’s running to lean. do you have any information or could help. thank you
Happy to Help, what main jet? What exhaust? And what intake? Have you tried to adjust your air fuel screw?. Thank you for watching and your sub Kalal. Let us know how this works out. Ride Safe and have a great day
@@TwoWheelRocco Much appreciated! My '02 Dyna was very neglected by the previous owner so it's been an adventure of tuning her up. Definite signs of running too rich for too long. I adjusted the idling screw to bring it to 1k rpm with choke fully pushed in. Then I started the mixture. When I closed that mixture screw all the way off, it was almost 3 full turns. Backed it out to 1.5 and she idled so much smoother. To double check I had it good, I left her running and slowly started closing the mixture screw down until the engine did it's slow stutter then reversed it until full recovery. Was exactly 1/2 turn. Readjusted the idler screw after that. Added a little seafoam to the tank to help clean any junk out and took her for a spin. So much smoother! The more things I take care of on this bike, the better it feels. Ride safe and have a great day too!
@@Senescense Happy to hear all things are going well. just cycle out the bad gas and the funk and she'll ride smooth again like you stated. Ride safe and have a great day and thank you for watching all your support Todd.
Great Videos, Sir! I got a 95th Anniversary Sportster XL1200C from 98, US-Import in 2016 and your Videos helped me a lot. Many Thanks and greets from Germany :)
You are the best at explaining stuff I swear. I think my bike is running lean I have an 06 Sportster and I changed the carburetor boot and intake seals after I used carb cleaner and it made the idle spike up but it still dies after I start it if I don’t have the choke at least halfway out. I had the carb re jetted at Harley Davidson but same problem. I’m going to replace the vacuum slide next. Anything else I should check?
Happy to help. I would not replace the slide. I think I would clean the pilot jet. I will send a video. They are very easy carburetors on these Harleys. Thank you for watching and your sub. Ride safe and have a great day. Take a look. ruclips.net/video/Pp4l-zbQcy0/видео.html. Let us know how this works out.
Rocco, I just successfully cleaned the carb and fired up a moth balled 1999 883 , after draining the oil tank which only had 3 cups I changed the filter and added 2 quarts. after running it for five minutes I checked the oil tank which was now full and over flowing. could there have been oil lingering in the crank case?
Yes, it's a dry sump motor and sitting for a period of time oil works its way into the motor and then you see it's low an add a quart and when you start the bike up the oil recycles to the oil tank and you end up at way too much oil. Clean air filter and remove oil. I like to see half way on your oil stick. Happy to hear you got her running. Thank you for your Sub. Ride Safe and have a great day.
My bike is running perfectly it’s a ‘97 1200xlc sportster. I want to change the air filter to the tc bros louvered air filter. Will I need to adjust my carb after switching the filter? Also how do you know where you’re starting your adjustment? Do you turn it all the way clockwise to start and go from there?
Happy to Help. There's a good chance you won't need to adjust anything. If you do turn the air /gas screw out which is counter clockwise no more than two full turns. If so you need a bigger idle jet. Thank you for watching and your sub Dave. Ride safe and have a great day.
I have a 06 1200xl c sportster. Starts great good response but when I push the choke all the way in the bike runs really slowly and can die while idle ing. I fucked with the idle speed screw and that helped do you think I should focus more of my attention on the airfuel mixture screw
I would take a look at your air filter. Clean filter with compressed air. How does she idle with your air filter removed from air box? How long have you been having this problem? Let us know how this works out. Thank you for your Sub Leif. Ride Safe and have a great day.
First I would checked the Petcock, I will send you a video on how to. ruclips.net/video/7Fo9Q93OJXI/видео.html. Is there any gas leaking from the carburetor onto the floor through that small black hose at the bottom of your float bowl. Any questions just ask. Thank you for watching and your sub Luke. Let us know how it works out. Ride safe and have a great day.
@@jacobjackson3791 Great question. Take a look at this video. ruclips.net/video/tS_-M4RuWc4/видео.html. It will help resolve your problem you have a bad float needle jet. Try to clean it once if that doesn't work buy a new float needle jet and your problem is solved. Let us know how it works out.
Great videos. I have a 06 twin cam that has no guts at wide open throttle, but when I back off just a bit acceleration is good. Carb has been jetted and I can smell gas at wot. I'm thinking too big of a main jet, or does air fuel screw affect wot? No black smoke and it's only a dog at wot 33 mpg
Happy to help. Did it always run this way? Make sure your air filters is clean with no oil on it. And then check oil level They like halfway on the dip stick when warm up. Do you know the jets you are running? What pipe and air intake? Any questions just ask. Thank you for watching and your sub Maria. Ride safe and have a great day.
My bike is an 02 883, itll pop at idle sometimes and lower rpms and sometimes stall on an idle but at the higher rpms and mid range it runs beautiful. Could this be a jetting issue or could this be caused by a lean condition?
My 03 883 has 2k miles on it. I replaced all fluids, put on a kn filter and took out the baffles. Now it’s sluggish to accelerate except when full throttle and sounds different and pops a lot especially on down shifting and deceleration. Good place to start? Screw adjust or bigger jets?
You will have to work the Jets. and A/F. When you remove that baffle on the stock pipe you have no back pressure. You should buy slip ons and start with them, Start with 45 idle / 180 main test and tune. let us know how it works out. Thank you for watching and your sub Bryan. Ride Safe and have a great day.
Hey Rocco, I did some all balls racing jet and needle kit on my 04. I’ve now noticed at high rpm my rev limiter is not the same and the bike sputters out at high rpm. I’ve tried a little tuning but what do you think my problem is it still seems to sputter out on rev limiter. Thanks man !
I don't really understand rev limiter, there is no rev limiter on a 04 XL1200 sportster. . That's a carbureted bike. Sounds like your jet is too big on your main and that's why it's sputtering out if it was not big enough, it would just lean out and rev with No Power. If it's sputters, it's too much fuel. What main jet did you put in there? Thank you for watching and all your support high RPM. Ride safe and have a great day. Let us know your jet sizes what pipe and what air intake?
Just got a 94' heritage softail bike has sat for some years, just did 3 hole fluid changes today bike struggles to hit 50mph so work to be done, will be doing this adjustment soon.

@@TwoWheelRocco when adjusting the idle adjustment screw where is the starting point? if the needle is set to even where the you can barely see it in the carb. do you back out from that point?
@@IRONTOSS When you adjust your idle screw, you just go clockwise to higher it counterclockwise to lower the idol. I usually like my idol and 1000 1100 RPMs. I hope that helps there's no point to start. It is the sound that you like of the motor idling. I like 1000 RPMs Hope that helped.
Thanks for the video. I just bought a Sportster 1200 and the previous owner put on a performance carburetor and some other parts that make it have a higher idle rpm. Can you use this to lower that and is that safe? Is it possible to lower the fuel amount too much?
Two Wheel Rocco thanks for the response! It has an Mikuni HSR 42-10 Carburetor. There’s a tube with a screw that extends the piece you were showing to change fuel amount. Not sure where to put the level. He also put on it Screamin’ Eagle Pro XL Performance Cylinder heads, R & I Clutch Plates. The other huge problem I have is that there is virtually no clutch play. Really wish I can slow the bike down. Thanks again for the help!
Let us know how this works out. Thank you for your Sub Jake. I myself use HD parts. Sorry I can't help much with that set up. Ride Safe and have a great day.
My son had bought his Sportster several months ago. Been having plugs foul out and not running smooth except at high rpm. Watched your video and went to check the mixture screw and it was set at three and a half turns. I reset it at two turns to start with. I'll keep an eye on the plugs regularly to see how they are doing. Thanks for the info.
Happy to help. Any questions just ask. What air filter and Exhaust are you running? Thank you for watching and your sub freebird. Ride safe and have a great day.

Hi Rocco... Today in the morning I just added a washer to the needle to have more fuel in the mix, I now have to adjust counterclockwise (or tighten the mix screw) to stop having black smoke is it true? Or I have a mistake adding the washer to the needle? I hope you can help me with that questions Running on a Dyna 88 Cubic inches. Thank you a lot for your video! God Bless You

@@TwoWheelRocco The bike was running slow when I acelerate so I decided to do that. The idle jet is 45 and the main jet is 195, running with Arlen Ness Air filter and Vance and Hines exhaust, new maniful seals and new diaphragm. I just have to adjust the air, fuel screw. If I have to much fuel I think i have to tight it more. Greetings from Mexico City!
Hey Roco I just put a new carburetor on my bike and it has a 185 jet. The factory recommendation for my bike is a 170. When I'm riding the bike and giving it full throttle it kind of hesitates. I'm wondering if this jet is causing the hesitation or perhaps the air-fuel mixture. So I guess my question is where would I start out at for tuning in terms of how many rotations?
I stumbled across your video and i was wondering if this applies to an elevation of 6800 ft up to 8000 ft. And back down to an elevation of 5000 ft. The 96 1200 sporster ran excellant at 5 to 7000 ft i now live at 7000 ft. Is a jet up needed to compensate for the lack of air?? Or will the enrichment screw do its job ...and not exceed the 2 turn rule?? Whats your thought ..
Happy to help. I don't think they'll be much of a difference at those altitudes. If there is, Turn out the Air/gas screw by 1/8 and see what that does. Let us know how it works out. Any questions just ask. Thank you for watching and your sub JW. Ride safe and have a great day.

Hi Rocco excellent videos, doubt, I have a '98 883, it starts without problems and stays on, but after driving about 2 or 3 miles it turns off, as if the carburetor tank had run out of gasoline (which is strange because it seems that it injects gasoline) I guess It could be the low jet, but I already did a general cleaning of the carburetor, if i wait for a 5 minutes, the bike start again but run for the 1 mile and turn off again cheers!!

Hey rocco, I got a 2005 sportster 1200 xl. I recently threw a 2-1 exhaust and oil cooler on for hot california riding. I had shotgun pipes before, running a 48 slow and 185 main. With the 2-1 i experienced black smoke at idle and fouled plugs so i put in a 45. I am not getting any adjustment in my mixture screw. I ran a 42, a 45, the 48. And rebuilt the carb completely 2 times and i cant get any response adjusting the mixture screw. Even with the 42 in and fully seated the bike would not stumble or elevate rpms when backed out. I started to get an intermittent high idle after coming to a stop light and checked for intake leaks. Nothing. Unplugged map sensor and intermittent high idle went away and would come back when plugged in. I put in a new map and no more random high idle. But still no change in sound or idle when adjusting mixture screw in both directions. Seems to be on the richer side even with a 42 at idle. I checked enrichener for good function and closing and pressure tested the path to rule out that leaking fuel at idle into the system. I can not figure out why im not getting any idle screw adjustment. Please help
Side note : float was adjusted to spec via service manual procedure and tolerances. I also had my father, a gulfstream jet mechanic and motor enthusiast, go through it with me. It has us both stumped. We also covered the small holes behind the micture screw hole and then seated the mixture screw to prove a seal when mixture screw is seated. We can not understand why the motor isnt reacting to adjustments of the screw with any size jet from 42,45, and 48 slow jet.
Happy to help it sounds like you're getting too much fuel and there is no adjustment I would test your Petcock or run the carburetor or a temporary fuel sauce and see what you got. Sounds like the diaphragm in your peacock is failing and you're sucking Fuel from another source, that would be the only reason that you have no fuel adjustment because you have too much fuel going to the carburetor and the black plugs. I hope this help any questions just ask thank you for all your support. Ride safe and have a great day. I will send you a video on how to test the Petcock..ruclips.net/video/7Fo9Q93OJXI/видео.htmlsi=8CG1rhn3DvhSHarA
Put all the play back in the cable, at the throttle. Mark carburetor with a little white nail polish and the cable to where that cable goes. so you have no problem replacing it later. it is indexed. You will have more than enough room to remove that cable cylinder from your carburetor. Any questions just ask I do not have a video on that but it is easy. Just do It..
My 80ci doesn’t let me adjust the idle screw without taking the air filter element completely. So how to know the correct setting when adjusting the screw with the bike running ? Because I’m theory the bike would be running leaner without the filter and that would make an incorrect setting

Hi, I have both a Intruder VS1400 and Marauder vz800,,,I have the bikes running well and synced and carbs inspected and set to spec,,,However the idle on both of these bikes is a bit off,,,AND upon bliping or reving the throttle on both bikes the idle hangs for a sec before returning to steady idle,,,from my under standing when this happens its typically a lean condition, conversely when you blip a throttle and it dips, then returns to idle its a rich condition,,,,,,,IS this issue solved by simply finding the correct mixture screw seting on both carbs? IF not do you have any other ideas for me to try? TY you have a great channel
Happy to help. Yes I would turn the air/ gas screw counter clockwise by a quarter turn that should reach in the mix on off Idle. Then see what your throttle response is. you will have to do that on both Carburator's. Let us know how it works ou.t that's where I would start. Thank you for watching and your sub daydreamer.

I've got a 05 sporty. Always has a a hard start but it'll start up after a few seconds..its got straight pipes. I watched your video on rejetting and thought that was my problem..but now I see this video and think maybe this is my issue? Any advice?
Should I screw the mixture bolt completely clockwise to stunt the gas flow and then turn it about one and five eighths counter clockwise (or until desired flow) to open it up? Or should I just start turning counter clockwise from its position now?
Happy to help, turn it clockwise and count your turns. until slightly seated. I like it at 1 3/4 to start my Air/Gas mix then adjust by eighth turn increments. Counterclockwise will written the fuel mix. Any questions just ask. I hope that helped. Thank you for watching and all your support Todd. Ride safe and have a great holiday.

I have a 1995 Harley Bad Boy and live in Florida (sea level) recently purchased from an owner in Atlanta. The bikes runs good when the choke is out but as the EVO motor warms up and I push the choke in it starts to sputter. There have been times that when I try and accelerate with choke off there is a loud “pop” and the carb and attached air cleaner actually “pop” off the manifold gasket and the bike immediately dies. I am assuming running too rich. Any help is appreciated.
Two Wheel Rocco - this is a completely stock 1995 Harley Bad Boy. It only has 8k miles on it - in a family collection before I purchased it so cleaning the carb would make some sense. I will perform this weekend. Maybe I should have put some fuel stabilizer in the bike when I received it as well. I have filled once with premium gas in the tank so far.
Take a look at these videos Gas removal Honda and Harley carb petcocks are very similar ruclips.net/video/c-gGr3mgaFw/видео.html.

Two Wheel Rocco - I cleaned my carb this weekend. The idle jet was definitely dirty from ethanol gas and prior owner didn’t run the Bad Boy but 8k miles in 25 years. Bad Boy now idles steady without choke on and smooth acceleration. This Florida summer weather pattern I had hard rain come in this afternoon and only got a few minutes to ride. Thanks again for the advice and videos. Very satisfied that I can work on my EVO and keep her on the road. I will definitely put miles on her, and only run premium gas so jets should stay clean. I miss the 1970’s leaded gas! ‘

Hey Rocco ... How many turns out for a 1997 stock carb Harley Dyna with a custom exhaust and a Big Sucker air cleaner? I noticed the rear spark plug was sooty but the front plug looked good. But the bike ran fine with no black smoke. I cleaned the plugs and started playing with the air fuel mixture screw. I started at 3 turns out and am now at 1 3/4 turns out, hoping the carbon won't reappear on the rear plug. How do I know where the "sweet spot" is? The bike had a great response at 3, 2.5, 2.0 and 1.75 turns out. do I keep leaning it out until the bike doesn't idle smoothly? Throttle response is good. On occasion, when decelerating I would hear the carb "spit" but not loud and only once. Should I bring the screw out until there is no spitting at all when decelerating?
Happy to help. With the air fuel screw, go out until it runs lousy then start going in until you find the best possible spot and see what that does for you. I like to have a clean rpm when I rev the throttle. Any questions just ask. Thank you for watching and all your support Alan. Ride safe and have a great day.

Hey Rocco, I have a 1980 sportser stock pipe, ss carb, when im idling it wants to die but when I go she wants to go hard? Is my adjustment screw on the top?
I have a 04, 883 put a new chineseum carb on it and it wouldn't hardly start. That screw was turned way out like 4 turns or so is that normal? When it did start as soon as I touched the throttle it died. Set it to approximately where you did and it starts but I had to idle it up to stop the popping. The original carb popped too, I replaced it because it was leaking fuel bad, actually caught fire today so that's why I put the China one on.
Happy to help Chinese Carburator never had luck with. You should've just rebuilt your CV Harley Davison Carburator you would've been much better off. if it was leaking gas through the quarter inch hose at the bottom that was just a float needle jet.

Hello rocco. My sportster 2001 carb was working good after i sent to recommended workshop to work on it. So far i put mileage on my bike about 250 miles . Today the bike carburetor starting to cough, stall and die. When tried to start the engine it wont fire up. Can you help me?
I would look at your Petcock for a vacuum leak, test your diaphragm might be failing. And check the vacuum line from your diaphragm vacuum line on the back of your petcock it could be old and collapsing. Things people just don't look at. this is the hose from your diaphragm to the back of the carburetor.

Sorry if this is a dumb question but if i was putting a high flow air cleaner on the bike would i be able to adjust the fuel to air ratio with this screw without having to re jet the carb?
No dumb questions, You will have to tune and test. What pipe are you running? And year and size? And miles? And are you talking about hi flow air filter not your HP intake.
Thank you for responding!! I have an 06 sportster with vance and hines short shots, its got approximately 8 thousand miles on it. I plan on putting a high flow cleaner on but didnt know if you had to re jet, or if it could just be tuned to run right. Once again thank you for taking time to respond your videos are very helpful and informative!
06 sportster with vance and hines short shots will need a Dyna Jet Kit for that setup. You will work your needle, main and idle jets and Air/Fuel screw to get that set up to run right. Thank you for your Sub. Tj. Let us know how this works out. Ride Safe and have a great day.
Thank you for all your help and videos! I was able to successfully re-jet the carb properly and during the process i ended up on another video of yours as i encountered a stripped screw on the bowl. So your vise grip trick really helped out i was able to get the job done your videos are VERY helpful when i have no clue what im doing lol.

Had to renew Bungie Bolts on my Dyna 1340cc 1995, but now runs very eratic, e.g. coughts/splutters, jerks when running at a constant speed, but ok when accelerating, also will not keep tickover. What do you think the problem is please.
I Just tryed this on a 90 evo. When i took the carb off the mix screw was backed out like 4 turns so i re set it to 1 and 3/4 and my throttle responce picked up significantly, but i still have a weird backfire at around 3500 rpm. The backfire was why i thought the mix was off. It also pops a bit on decel. I never noticed any smoke from the bike last season. I rode it all summer and just ignored the backfire. Being backed out 4 turns I would figure it should of smoked. Any ideas? Am i just sucking air from somewhere?
Rocco, love your channel. Question, If i have the carb in my left hand (still attached to the bike by the linkages), and I'm adjusting the air/gas screw with my right, what do you consider "1 full turn"? Is it going from12 o'clock, to 12 o'clock?
Yes. Turn it in and then turn it out one and three-quarter turns. Let us know how it works out. Happy to help. Any questions just ask thank you for watching and your sub. Ride safe and have a great day.

sometimes with newer bikes you gotta reset your idle by turning your bike to run for 10seconds 4x to reset your idle but thats usually if your bike idles good then gets faster n faster, I would try the carb first before doing that tho

When I removed the plug, I found my screw already adjusted to the "sweet spot" that you recommend, 1 5/8 out. I left it there. I've had no black smoke and my spark plugs were light tan when I changed them with 10K miles on them. The only adjustment I needed to do was replace my stock #42 pilot jet with a #45 one to eliminate the cough on take-off, which I referred to in my comment on your video on replacing jets.

I took your advice and replaced my Petcock because the bike was running very rough after 30 minutes of riding. It was idling very fast, then I watched this video and found one of the hose lines was cracking at the bottom of carb. I fixed that and now the 2006 sportster custom is running much better.

Thanks for this Rocco! I think my 04 sporty is running rich. New plugs in and the ends are BLACK after 1 run. Rear cylinder is occasionally doing a little misfire whilst running too. Going to adjust the mixture screw and see how it goes from there. Learning loads from your videos mate, thanks a bunch!
Happy to help, remember it's a most important to have a clean air filter. If you run your hand under your air filter and there's oil on your fingertips there's a good chance you have too much oil in the motor. Check the oil dipstick, halfway full is where these motors run their best. Otherwise they will foul your plugs. Too much oil in the motor. This will result in a dirty air filter and a terrible riding bike. I hope this helps. Thank you for watching and your sub drinkster. Ride safe and have a great day. Let us know how it works out.
@@TwoWheelRocco To confirm, keep your oil level at HALF full on your dipstick? Is this true for big twin evo engines too or just sportsters?
@@TwoWheelRocco I have a '97 Evo engine. What is the best main jet, idle/slow jet should I use for that bike? What about needle jet? thx.
Would the mixture screw keep my 883 sportster from running above 70 mph runs and drives fine but wont get above 70
Does the screw bottom out? Then you back it off 1 and 3/4?
Yes it does bottom out then bake it out. That is correct. Thank you for your support.
This is very very helpful. Reading through the comments, i think i may have narrowed down and pinpointed my issue. Plug fouling. I get my fuel mixture and idle just perfect, then 200 miles down the road, she starts backfiring. I pull the plugs and they are dry and black. Im betting its the exhaust. The previous owner slapped some shotgun exhaust on it. My bet is i need to swap out the jets. Whats your opinion with this limited information? Its a 91 883. Fuel mixture is at one and a little over a half turns and the idle is at 900 rpm.
Happy to help. I would test the Petcock first. That's where it all starts. Make sure the peacock holes vacuum. If the diaphragm is failing, that means it won't hold vacuum and it will leak gas and not operate properly which equals a poorly running motor. check the vacuum line from your carburetor to the back of your Petcock or bottom. I will send you the video. Any questions just ask. ruclips.net/video/7Fo9Q93OJXI/видео.htmlsi=MfomcbF3wze-rO5b thank you for watching and all your support Jack.. Let us know how it works out.

Great video. I have an 05 883 custom. Idle is great will run all day. But as soon as I turn the gas to take off it backfires through the carb and stalls or almost stalls out and dies. Thinking the carb may need a good cleaning but I'd like to get you're opinion. Thanks and have a good day
I would check your carburetor excelerator pump diaphragm. Remove air filter cover, Twist throttle and look to see if gas squirts gas into your carb. If it does, then check vacuum lines coming off your petcock. Let me know how this works outruclips.net/video/7Fo9Q93OJXI/видео.html Take a look, hope this helps.
My 2005 883 standard did this until I changed my pilot/idle jet from a 42 to a 45. This change also eliminated the "cough" on take off when the engine was the slightest bit cool, regardless of air temperature.
I appreciate your video, Its almost identical to my 02 sporty. Got me all straightened out. See you out on the road. Stay safe.
Happy all went well. Thank you for watching all your support Landshapeslick. Ride safe and have a great day.
Rocco, bought an 05 Twin 88, stock carb, unknown 2 into 1 with baffle, high flow filter. Was set at 3 turns, plugs look pretty good, a bit sluggish at higher rpm, set at two turns, runs much better but plugs turning a bit to the grey side. But runs great! No backfire, nor did it at 3. Think I should go to 2.5 because of plug color? Couldn’t tell you how jetted. But if it runs good and plugs look good, should I just leave it?
One more question. The mixture screw affects the mixture throughout the complete range of throttle, not just idle, doesn’t it? And thank you?
Helps with transition from idle to mid range. but it all adds up in the end. I would leave it at two turns. That tells me the Jets are right size. Hope this helps thank you for your sub Yoso.. Ride safe and have a great day.

@@TwoWheelRocco Much appreciated! My '02 Dyna was very neglected by the previous owner so it's been an adventure of tuning her up. Definite signs of running too rich for too long. I adjusted the idling screw to bring it to 1k rpm with choke fully pushed in. Then I started the mixture. When I closed that mixture screw all the way off, it was almost 3 full turns. Backed it out to 1.5 and she idled so much smoother. To double check I had it good, I left her running and slowly started closing the mixture screw down until the engine did it's slow stutter then reversed it until full recovery. Was exactly 1/2 turn. Readjusted the idler screw after that. Added a little seafoam to the tank to help clean any junk out and took her for a spin. So much smoother! The more things I take care of on this bike, the better it feels. Ride safe and have a great day too!

Rocco, I just successfully cleaned the carb and fired up a moth balled 1999 883 , after draining the oil tank which only had 3 cups I changed the filter and added 2 quarts. after running it for five minutes I checked the oil tank which was now full and over flowing. could there have been oil lingering in the crank case?
Yes, it's a dry sump motor and sitting for a period of time oil works its way into the motor and then you see it's low an add a quart and when you start the bike up the oil recycles to the oil tank and you end up at way too much oil. Clean air filter and remove oil. I like to see half way on your oil stick. Happy to hear you got her running. Thank you for your Sub. Ride Safe and have a great day.
My bike is running perfectly it’s a ‘97 1200xlc sportster. I want to change the air filter to the tc bros louvered air filter. Will I need to adjust my carb after switching the filter? Also how do you know where you’re starting your adjustment? Do you turn it all the way clockwise to start and go from there?
Happy to Help. There's a good chance you won't need to adjust anything. If you do turn the air /gas screw out which is counter clockwise no more than two full turns. If so you need a bigger idle jet. Thank you for watching and your sub Dave. Ride safe and have a great day.
I have a 06 1200xl c sportster. Starts great good response but when I push the choke all the way in the bike runs really slowly and can die while idle ing. I fucked with the idle speed screw and that helped do you think I should focus more of my attention on the airfuel mixture screw

My bike is an 02 883, itll pop at idle sometimes and lower rpms and sometimes stall on an idle but at the higher rpms and mid range it runs beautiful. Could this be a jetting issue or could this be caused by a lean condition?

My 03 883 has 2k miles on it. I replaced all fluids, put on a kn filter and took out the baffles. Now it’s sluggish to accelerate except when full throttle and sounds different and pops a lot especially on down shifting and deceleration. Good place to start? Screw adjust or bigger jets?
You will have to work the Jets. and A/F. When you remove that baffle on the stock pipe you have no back pressure. You should buy slip ons and start with them, Start with 45 idle / 180 main test and tune. let us know how it works out. Thank you for watching and your sub Bryan. Ride Safe and have a great day.

Hey Rocco, I did some all balls racing jet and needle kit on my 04. I’ve now noticed at high rpm my rev limiter is not the same and the bike sputters out at high rpm. I’ve tried a little tuning but what do you think my problem is it still seems to sputter out on rev limiter. Thanks man !
I don't really understand rev limiter, there is no rev limiter on a 04 XL1200 sportster. . That's a carbureted bike. Sounds like your jet is too big on your main and that's why it's sputtering out if it was not big enough, it would just lean out and rev with No Power. If it's sputters, it's too much fuel. What main jet did you put in there? Thank you for watching and all your support high RPM. Ride safe and have a great day. Let us know your jet sizes what pipe and what air intake?

Two Wheel Rocco thanks for the response! It has an Mikuni HSR 42-10 Carburetor. There’s a tube with a screw that extends the piece you were showing to change fuel amount.

@@TwoWheelRocco The bike was running slow when I acelerate so I decided to do that. The idle jet is 45 and the main jet is 195, running with Arlen Ness Air filter and Vance and Hines exhaust, new maniful seals and new diaphragm. I just have to adjust the air, fuel screw. If I have to much fuel I think i have to tight it more.
Greetings from Mexico City!
Hey Roco I just put a new carburetor on my bike and it has a 185 jet. The factory recommendation for my bike is a 170. When I'm riding the bike and giving it full throttle it kind of hesitates. I'm wondering if this jet is causing the hesitation or perhaps the air-fuel mixture. So I guess my question is where would I start out at for tuning in terms of how many rotations?
What motor, pipe and intake?
I stumbled across your video and i was wondering if this applies to an elevation of 6800 ft up to 8000 ft. And back down to an elevation of 5000 ft. The 96 1200 sporster ran excellant at 5 to 7000 ft i now live at 7000 ft. Is a jet up needed to compensate for the lack of air?? Or will the enrichment screw do its job ...and not exceed the 2 turn rule?? Whats your thought
..
Happy to help. I don't think they'll be much of a difference at those altitudes. If there is, Turn out the Air/gas screw by 1/8 and see what that does. Let us know how it works out. Any questions just ask. Thank you for watching and your sub JW. Ride safe and have a great day.
What’s a good rule of thumb on the idle screw before adjusting the mixture screw?
Happy to help. Set it to an idol you like. Then the air Fuel screw, set at 1 3/4 turns open. Start the bike and then make adjustments to Air Gas screw. Test Rides. Hope that helps. That's how I start off. my tune. Thank you for watching, and all your support pork chop screen printing. Ride safe and have a great day.
Hi Rocco excellent videos,
doubt,
I have a '98 883, it starts without problems and stays on, but after driving about 2 or 3 miles it turns off, as if the carburetor tank had run out of gasoline (which is strange because it seems that it injects gasoline) I guess It could be the low jet, but I already did a general cleaning of the carburetor, if i wait for a 5 minutes, the bike start again but run for the 1 mile and turn off again
cheers!!
Happy to help. They are notorious for ignition modules failing. The bike will run, warm up and die sit for five minutes start up run and the modulated fails because of the heat. time to replace your ignition modulator.

Hey rocco, I got a 2005 sportster 1200 xl. I recently threw a 2-1 exhaust and oil cooler on for hot california riding. I had shotgun pipes before, running a 48 slow and 185 main. With the 2-1 i experienced black smoke at idle and fouled plugs so i put in a 45. I am not getting any adjustment in my mixture screw. I ran a 42, a 45, the 48. And rebuilt the carb completely 2 times and i cant get any response adjusting the mixture screw. Even with the 42 in and fully seated the bike would not stumble or elevate rpms when backed out. I started to get an intermittent high idle after coming to a stop light and checked for intake leaks. Nothing. Unplugged map sensor and intermittent high idle went away and would come back when plugged in. I put in a new map and no more random high idle. But still no change in sound or idle when adjusting mixture screw in both directions. Seems to be on the richer side even with a 42 at idle. I checked enrichener for good function and closing and pressure tested the path to rule out that leaking fuel at idle into the system. I can not figure out why im not getting any idle screw adjustment. Please help
Side note : float was adjusted to spec via service manual procedure and tolerances. I also had my father, a gulfstream jet mechanic and motor enthusiast, go through it with me. It has us both stumped. We also covered the small holes behind the micture screw hole and then seated the mixture screw to prove a seal when mixture screw is seated. We can not understand why the motor isnt reacting to adjustments of the screw with any size jet from 42,45, and 48 slow jet.
Happy to help it sounds like you're getting too much fuel and there is no adjustment I would test your Petcock or run the carburetor or a temporary fuel sauce and see what you got. Sounds like the diaphragm in your peacock is failing and you're sucking Fuel from another source, that would be the only reason that you have no fuel adjustment because you have too much fuel going to the carburetor and the black plugs. I hope this help any questions just ask thank you for all your support. Ride safe and have a great day. I will send you a video on how to test the Petcock..ruclips.net/video/7Fo9Q93OJXI/видео.htmlsi=8CG1rhn3DvhSHarA
Also, do you have a video on how to remove the carb, showing how to disconnect the throttle cables, and how to place them back on the carb?
Thanks
Put all the play back in the cable, at the throttle. Mark carburetor with a little white nail polish and the cable to where that cable goes. so you have no problem replacing it later. it is indexed. You will have more than enough room to remove that cable cylinder from your carburetor. Any questions just ask I do not have a video on that but it is easy. Just do It..
You doing great job brother thank you for cheating things get done this is free learning school 👍👍👍👍
My 80ci doesn’t let me adjust the idle screw without taking the air filter element completely.
So how to know the correct setting when adjusting the screw with the bike running ? Because I’m theory the bike would be running leaner without the filter and that would make an incorrect setting

Hi, I have both a Intruder VS1400 and Marauder vz800,,,I have the bikes running well and synced and carbs inspected and set to spec,,,However the idle on both of these bikes is a bit off,,,AND upon bliping or reving the throttle on both bikes the idle hangs for a sec before returning to steady idle,,,from my under standing when this happens its typically a lean condition, conversely when you blip a throttle and it dips, then returns to idle its a rich condition,,,,,,,IS this issue solved by simply finding the correct mixture screw seting on both carbs? IF not do you have any other ideas for me to try? TY you have a great channel
Happy to help. Yes I would turn the air/ gas screw counter clockwise by a quarter turn that should reach in the mix on off Idle.

Happy to help. How is the choke knob on your bike, does it work? Thank you for watching and your sub Glenn. Let us know.
Should I screw the mixture bolt completely clockwise to stunt the gas flow and then turn it about one and five eighths counter clockwise (or until desired flow) to open it up? Or should I just start turning counter clockwise from its position now?
Happy to help, turn it clockwise and count your turns. until slightly seated. I like it at 1 3/4 to start my Air/Gas mix then adjust by eighth turn increments.

I have a 1995 Harley Bad Boy and live in Florida (sea level) recently purchased from an owner in Atlanta. The bikes runs good when the choke is out but as the EVO motor warms up and I push the choke in it starts to sputter. There have been times that when I try and accelerate with choke off there is a loud “pop” and the carb and attached air cleaner actually “pop” off the manifold gasket and the bike immediately dies. I am assuming running too rich. Any help is appreciated.
Clean carb. What carb, intake and pipe is on your bike?
Two Wheel Rocco - this is a completely stock 1995 Harley Bad Boy. It only has 8k miles on it - in a family collection before I purchased it so cleaning the carb would make some sense. I will perform this weekend. Maybe I should have put some fuel stabilizer in the bike when I received it as well. I have filled once with premium gas in the tank so far.
Take a look at these videos Gas removal Honda and Harley carb petcocks are very similar ruclips.net/video/c-gGr3mgaFw/видео.html.

Two Wheel Rocco - I cleaned my carb this weekend. The idle jet was definitely dirty from ethanol gas and prior owner didn’t run the Bad Boy but 8k miles in 25 years. Bad Boy now idles steady without choke on and smooth acceleration. This Florida summer weather pattern I had hard rain come in this afternoon and only got a few minutes to ride. Thanks again for the advice and videos. Very satisfied that I can work on my EVO and keep her on the road. I will definitely put miles on her, and only run premium gas so jets should stay clean. I miss the 1970’s leaded gas!

Hey Rocco ... How many turns out for a 1997 stock carb Harley Dyna with a custom exhaust and a Big Sucker air cleaner? I noticed the rear spark plug was sooty but the front plug looked good. But the bike ran fine with no black smoke. I cleaned the plugs and started playing with the air fuel mixture screw. I started at 3 turns out and am now at 1 3/4 turns out, hoping the carbon won't reappear on the rear plug. How do I know where the "sweet spot" is? The bike had a great response at 3, 2.5, 2.0 and 1.75 turns out. do I keep leaning it out until the bike doesn't idle smoothly? Throttle response is good. On occasion, when decelerating I would hear the carb "spit" but not loud and only once. Should I bring the screw out until there is no spitting at all when decelerating?
Happy to help. With the air fuel screw, go out until it runs lousy then start going in until you find the best possible spot and see what that does for you.

I have a 2005 RK 14000 miles with SE air cleaner and muffler , true duals.Pilot jet 48 and main jet 180.There is a EZ Just mixture screw.The needle was changed for a cvp velocity needle and cvp V- ductor.The mixture screw is at 3 1/8 turns out.The pipes are black and instead of getting 190 miles out of the tank before reserve ,I only get 170,but it runs great.Whats happening.?Also there are oil spurts out from air cleaner to the saddle bags.
Happy to help. That is an 88 motor I believe you should have 45, idle 180 main one and three-quarter turn on the air fuel screw and see what you got then you can make the final adjustments on the float needle. Let us know how it works out, that's the reason why you burning so much gas.Any questions just ask. Thank you for watching all your support brunorolland. Ride safe and have a great day.
Thank you for all the videos brother they've been a huge help
Happy to Help. Thank you for watching and your Support Matt. Let us know how this works out. Ride Safe and have a great day.
Not quite got that .. clock wise in lessees fuel got it .. but do u bottom it out clockwise & then back off CCW 1 1/2 to 2 turns ?? Thanks for verification
Sorry I did not make that clearer. Yes, Bottom it out clockwise & then back off CCW 1 1/2 to 2 turns for more fuel. Hope that helps. Let us know how this works out.
@@TwoWheelRocco Hi & yes sir it sure does ...thanks so very much for that info I thought so but wasn't absolutely SURE ...... appreciate the quick response back ...I just subscribed today & have watched several of uR videos already just today ..Thanks again
@@heatingairservices8708 Thank you, Any questions just ask.
I turned mine out to 1.5 turn then too 2.. back to 1.4.... it was pops when I get on it... even at idle it pops... what I'm i doing wrong... thanks
Sounds like to much fuel.. Check you petcock. Take a look at this video. ruclips.net/video/7Fo9Q93OJXI/видео.html. test your petcock diaphragm for leaks. This will cause gas into your intake.. Let us know how this works out. Thank you for watching and your sub Brian. Ride Safe and have a great day.
I dont know if it was mentioned but ensure whatever vehicle you're adjusting a carb on is at normal operating temperature. This is vital.
Happy to help, I agree, tuning your motor at operating temperature is essential. Thank you for your input. Thank you for watching and your sub Justin. Ride Safe and have a great day.
Sorry if this is a dumb question but if i was putting a high flow air cleaner on the bike would i be able to adjust the fuel to air ratio with this screw without having to re jet the carb?
No dumb questions, You will have to tune and test. What pipe are you running? And year and size? And miles? And are you talking about hi flow air filter not your HP intake.
Thank you for responding!! I have an 06 sportster with vance and hines short shots, its got approximately 8 thousand miles on it. I plan on putting a high flow cleaner on but didnt know if you had to re jet, or if it could just be tuned to run right. Once again thank you for taking time to respond your videos are very helpful and informative!
06 sportster with vance and hines short shots will need a Dyna Jet Kit for that setup. You will work your needle, main and idle jets and Air/Fuel screw to get that set up to run right. Thank you for your Sub. Tj. Let us know how this works out. Ride Safe and have a great day.
Thank you for all your help and videos! I was able to successfully re-jet the carb properly and during the process i ended up on another video of yours as i encountered a stripped screw on the bowl. So your vise grip trick really helped out i was able to get the job done your videos are VERY helpful when i have no clue what im doing lol. Have a great evening and thanks again for the advice and the videos!!
Im stumped Rocco CV carburator has an extra valve on the same side as fuel valve but at bottom of intake barrel?
Happy to help. If you could send pic.I believe that's just a vent. to erocco3964@gmail.com. Thank you for watching and your sub Dan. Ride safe and have a great day.
Had to renew Bungie Bolts on my Dyna 1340cc 1995, but now runs very eratic, e.g. coughts/splutters, jerks when running at a constant speed, but ok when accelerating, also will not keep tickover. What do you think the problem is please.
I would love to help but what is. Tickover? Bungie Bolts?
I Just tryed this on a 90 evo. When i took the carb off the mix screw was backed out like 4 turns so i re set it to 1 and 3/4 and my throttle responce picked up significantly, but i still have a weird backfire at around 3500 rpm. The backfire was why i thought the mix was off. It also pops a bit on decel. I never noticed any smoke from the bike last season. I rode it all summer and just ignored the backfire. Being backed out 4 turns I would figure it should of smoked. Any ideas? Am i just sucking air from somewhere?
Do you know the Jets that you are running in this evo. Thats where I would start. I like 1 3/4 AF.setting. What pipe and what intake?
@@TwoWheelRocco Factory pipe and intake. Ill remove the jets tommorow and let you know. What size should they be?
Rocco, love your channel. Question, If i have the carb in my left hand (still attached to the bike by the linkages), and I'm adjusting the air/gas screw with my right, what do you consider "1 full turn"? Is it going from12 o'clock, to 12 o'clock?
Happy to help. Exactly 12 to 12 would be one full time.. Thank you for watching and your sub.Dan. Ride Safe and Have a great day.
I went all the way in mixer it stayed running should I put the 45 jet back in
I would and see what the differences is. Let us know.
So do you turn the screw all the way in until it stops then turn it out 1 and 3 quarters? Mine hesitates when I turn the throttle.. love ur videos tho
Yes. Turn it in and then turn it out one and three-quarter turns. Let us know how it works out. Happy to help. Any questions just ask thank you for watching and your sub. Ride safe and have a great day.
Rocco my buddy told me that my sportster is running a bit lean...how could I adjust my carb to make it better....I noticed when I’m riding it sounds like it’s topped out and struggling
Air Fuel Adjustment. Turn that screw out. and that will be richer.
Hey Rocco i have a 2016 sportster iron 883 and when i hit the throttle it just makes loud noise but wont go
Happy to help. I agree they're not fast bikes. Do you think there's something wrong with your Sportster. Thank you for watching and all your support Adrian. Ride safe and have a great day.
