How To Harley Davidson Sportster Carburator Re-jetting.

- Опубликовано: 29 сен 2024
- Harley Davidson Sportster Carburator Re-jetting. This was done on an XL1200 with Screamin Eagle Exhaust. With an open air cleaner. Stock this would have an 45 pilot and an 180 main jet. We installed an 48 pilot and 185 main. Two turns out on Air fuel screw. And this cleaned up the lean fuel condition that would cause popping and spitting.
Any Questions just ask.

Hey Rocco, I know I speak for most viewers, by far you’re the absolute best Harley mechanic and your instructional videos are phenomenal. Please keep it up - we value what you share with us because it helps us to be better bike owners and caretakers of our bikes.
I have an '06 with the same slip ons, but stock air. This is great. Now I have the confidence to get in there and see what I got. Thank you! (no pops, but occasional carb fart, misfire)
Happy to Help, Any questions just ask. Thank you for your Sub Bradley. Take a look at this video. ruclips.net/video/G1XD0hHtwCw/видео.html Ride Safe and have a great day.
I also have an occasional fart and misfire, did you fix the problem? if so, what fixed it? rejetting it? When I bought my bike it already had screaming eagle slip ons and stage one screaming eagle air cleaner, but occasionally is farts and misfire. I wonder what that could be. Thanks in advance.
You need to rejet or maybe even adjusting your air fuel screw will fix it@@zdleggett8876
Damn, that sounds sweet! Add an Andrews cam, a thunderheader, high-flow intake air cleaner and jetting... you're building monsters! Just bought a garaged '99 1200C for 1k (and a, holygeez, it has a Thunderheader, and only 9k miles), and I am so feeling beyond charmed!!! Great video, mad scientist!! :)

@@TwoWheelRocco I definitely will. Your videos have popped up multiple times while I have been fixing up this bike. Unfortunately I have a lot more to do now after a dog ran out in front of me on the highway. I have to replace the exhaust and air box so I figured I might as well upgrade to performance parts with the insurance money. I've been joking with people that it will be better then before and it only cost a knee instead of an arm and a leg. Lol
Any questions just ask. Thank you for your support. Let us know how it works out.
@@TwoWheelRocco I got it done. Even before putting the new exhaust on there was a huge difference. It sounds like a completely different bike now.
Happy to hear all went well. Thank you for your Support. Ride Safe and have a great day.

Two Wheel Rocco I will ask, I’ll try to make it short, I’m sure that u have a video for my Very intermittent issue ! ‘’06 HD 1200 XL C; 6100 miles. Runs great, but at stops, stop songs lights, traffic ECT! She’ll burp, fart, miss Start to stall, engine light comes on, I work the throttle to keep it alive! Get to next STOP all is fun; very intermittent! New petcock n filter, vacuum line new, map sensor working! Watched your other carb video the other day, removed carb took it apart the low end, no junk in bowl or jets, which I removed and sprayed plenty of carb spray- gumout! Took out air mixture screw cleaned ! Set it at 1 3/4 turns. Same issue; intermittent. Went to HD yesterday new accelerator pump, spring and those mini O rings! Road tested Same thing! I’m stubborn and determined WTF
Try raising your idle a little. When a motor will not idle on deceleration usually there's an air issue and that's why she stalls, the air gas mixture is lean. Spray some carb cleaner around your intake and vacuum lines around your carb and see if the idle raises if it does you are sucking air around that area. Hope this helps.
Two Wheel Rocco
Ok, I’m playing with the idle, bought a cost effective tach to see be ck mark/reference point. 2 weeks ago I changed both intake gaskets, rear cylinder had a vacuum leak, carb to intake seal is also new. Been spraying carb-cleaner around above incase I didn’t seal intake to heads properly, checked tightness of the intake bolts when I pulled carb the other day. What didn’t due; was check was number on main jet and air fuel jet, saw u today and said dang had them out! I will do that see what numbers they are! I’ll do as u advise! Stay tuned! Tinker
Two Wheel Rocco sorry about typos n grammar it’s a Jersey thing LOL
i have the same bike. you just solved my issues with it. thank you.
Glad I could help. Ride safe and have a great day. Let us know how it works out.

Really enjoy your videos Rocco, keep them coming! 👍
Would like to have heard the spitting before the change.
Sorry about that, But you will know it when your bike does it. Thank you for your Support. Any questions just ask.
Great collection of Videos! You have a 1200 I have a 883. What jet sizes do I have and what size do I move up to because of open headers. And How many washers do I need?
How does she run and Idle? Three washers under the needle is where I would start. You will need to open your carburetor and look to be sure. Stock would be 42 starter 165 main. open pipe, is it a full open short exhaust pipe? What intake are you running? Let us know how that works out. Thank you for watching and your Sub Craig. Ride Safe and have a great day.
I have vance and hines short shots and arlen ness big sucker, would my require the same jet upgrade ? Mine only seems to spit if it hasnt been rode a few miles to warm it up. Ocassionally i get what sounds like a big puff of air coming from the breather when i lay on the throttle is that spitting too ?
Yes I would try 48 pilot 185 or 190 main. 3 washers under the needle.. 2 turns out on A/F screw. Let us know how this works out. Thank you for your Sub M B. Ride Safe and have a Great Day.
Hey Rocco, thank you for the great video! I always learn from these. I have a 97 sportster; completely stock. It has a bad spit whenever warming up, mostly when it’s cold. I’m putting a new jet in today and, cleaning the pilot (should have bought one, now I know). Should I start with seeing if that solves my issue, then more forward to a quarter turn to add a little fuel? Or should I do both to start. Thank you again for posting and reading our comments!
Happy to help. Usually I would put it together and start off with the stock settings and then test ride. You'll be able to tell how she's running any questions just ask.. Thank you for watching in your sub Christian. Ride safe and have a great day. Let us know how it works out.
Great video bro!
Happy to Help, Any questions just ask. Thank you for your Sub. Ride Safe and have a great day.
Where do you get the jets?? I can only find rejets for S&S carbs. Or will those jets work on the stock carb?? If so, still where do you get them??
Happy to help thank you for watching Vincent. I buy my jets on eBay, take a look. www.ebay.com/itm/Carbruetor-Carb-Main-Pilot-Jet-for-Harley-Davidson-CV-40-XLH883-XLH1200/353154416896?fits=Make%3AHarley-Davidson&hash=item5239a4c100:g:0qAAAOSwnJJfIkMp. Hope this help, Let us know how this works out. Ride Safe and have a great day.
@@TwoWheelRocco thanks man. I ended up finding them on Dennis Kirk. Ordered a bunch of different sizes. For 3 bucks a piece you can’t beat it. I have Vance and Hines short shots with an Arlen Ness bug sucker air cleaner on a 04 1200c. Once I get the jets in there I’ll let you know what the perfect ratio for this set up is. Thanks for all the help and the great videos.
Tonight i left in a hurry and gave my 1996 XLH 1200 little choke as usual but didnt give it time to warm up. it was about 10 degrees celcius. rode about a mile or so downhill and as soon as i hit the motorway and gave it some gas it just sputtered and died. took me some time to get it going again. Was that just becuse i didnt give it time to warm up or? btw awesome channel, just subbed:)
Try again tomorrow with the choke out and see if anything changes let us now? How long have you owned this Sportster? Thank you for your Sub. Any questions just let us know. Ride Safe and have a great day.
@@TwoWheelRocco This sportster is new to me. rode it in total 200 miles or so but now its getting colder and i think im just rushing it too much. will let it heat up a little better before giving it the beans. its been performing flawlessly until this issue.
Currently running 46 pilot(idle) jet and a 185 main jet, with a 2 into 1 V&H exhaust, I feel like its still not enough, and like it should pull harder
Higher the main 195 and lift the needle three washers. Take a look at this video. ruclips.net/video/G1XD0hHtwCw/видео.html. Test and tune. Let us know how this works out. Thank you for watching and you sub Joglock. Ride safe and have a great day
Subscribed bud and does it depend on the pipes you use and intake or is it the same scenerio
Happy to help. I would start there and then if you have to adjust your slide needle or your air/fuel, April 4 everything's a little different depending on the pipe and the intake yes. Any questions just ask, what pipe and intake are you running? Thank you for watching and all your support Brian . Ride safe. Have a great day.
Great videos thank you. If I go back to my stock pipes, do I have to go back to stock jets?
Yes you do. Thank you for Sub Gabriel. Any questions just ask. Ride safe and have a great day
@@TwoWheelRocco thank you sir. 👍🏽
Hey Rocco, im here again and Im having trouble taking off the main jet from the copper housing. how did you get off that 180 jet and replace it with the 185 jet?
Happy to help. That's the emotion Tube the main Jets connected to, pull the whole thing out with a socket what pliers I like little vice grips. . Hold it with an vice grip and loosen the jet up. Hope that helps. That's how I do it. Sometimes they get tight but I like to remove the whole thing from the carbureter, let us know how it works out. Any questions just ask. Thank you for all your support. Ride safe and have a great day.
Great content! This is helping me work on my sporty... Any chance you could put out a video on how to rebuild rear master cylinder for a sportster? :)
Great suggestion! Next time I get one I will do it.
Awesome thank you!
Thanks so much! Bill M

Great info Rocco, I have a 2004 Sportster identical to this one and have been battling carb coughing & spark plug soot for over 6 mths. I purchased mine used with SE II pipes and the same air cleaner as the one in this video. Like I said basically same bike (color and all). So far I found a leak in carb seal due to needing a new seal gasket. That got rid of carb cough but I still have the other issue which is the plugs are black, no matter what plugs I use (even tried the SE II plugs). Checked carb has 45 low and 180 main. Its weird, the bike has a surge on throttle from low to high which I think indicates the need for rejetting as your video suggest but again the plugs are always black with soot? New Carb time? Since I have no idea what previous owner may have done (drilled). Lost at this point, please help!
I would start with Testing your petcock, sounds like you have a diaphragm leak which would creating a rich situation, by gas being pulled threw your vacuum line into your intake ruclips.net/video/7Fo9Q93OJXI/видео.html. then I would try washers under the needle to give you a little more performance off idle. ruclips.net/video/G1XD0hHtwCw/видео.html. Any questions just ask. Thank you for watching and your sub JB. Let us know how this works out. Ride Safe and have a great day.
Thanks good info
Happy To Help, Any questions just ask. Thank you for watching and your sub wschevyrider. ruclips.net/video/BDD61HMhQfE/видео.html. Safe and have a great day.
How do you tell if its to rich after you set it? Thanks
Most times it will be a secondary reason why you have a rich condition like Petcock Diaphragm failing and letting gas pass into that vacuum hose coming off your petcock then into your intake that is the most common reason why motorcycles run rich or a very dirty air filter. The way to tell is to look at your spark plugs. How is your bike running now?
hi. i bought xlh1200 1991. and it realy struggling to go faster then a 70 mpg. is that normal? It starts to vibrate very badly after 60mpg. Then i saw this video and I noticed that you carb vaccum cylider is lifting on every trotle touch, mine dosent move, could that be a problem?
Happy to help. Start by cleaning the carburetor and checking what jet you're running and yes, the slide should move as accelerator pump, Spits gas into your intake of your Carburator. Any questions just ask. Thank you for watching and all your support David. Ride safe and have a great day.
Do you have a carburetor kit parts number for this carburetor with the different size jets?
Happy to help. Find out what size jets and I will help you find the Jets that you need. I do not know a kit with Jets . Thank you for watching and all your support William. Ride safe. Have a great day.
Okay so I cut the baffles out of my exhaust mine is a 2009 xl 1200 sporty bone stock it’s seems to do a little back firing coating down hills and takes it’s time warming up would rejetting it be the solution?
I would buy some slip on pipes and start from there. that exhaust system you have now is NG. You'll have no torque. Thank you for watching and have a great day.
I have the same year sportster with a full 2 into 2 exhaust and am going to order a Arlene Ness big suckered intake. How do I decide my jet sizes?
Happy to help. What jet you are running? Make adjustments that have been suggested in the video. Any questions just ask. Thank you for watching and your sub. Caleb. Ride safe and have a great day.
Thanks for this video! I have a 2005 1200C, that is stage one , like in this video. Carb had a 42/175 in it the first time I opened it up. I upgraded it to 45/180. The bike starts rough, as in I need a full choke to start cold. Once I start going highway speed, I cut it to half; at a mile and off at too. At that point, it will start and run well without a choke. Let it sit 30 minutes and the process needs to start all over. Makes it tough if I start off at the house and want to make quick stops in the city, it will never warm up at 35 mph. I seen another subscriber have success with a 48/190. Is that what you would go with?? Also, I have some minor decel popping, dropping off the accelerator at highway speeds. This is very hard to hear, better since I corrected exhaust leak! Thanks for your video, and thanks for any advice you can offer
Try 48 / 190 and 2turns on your Air Gas screw, Then adjust in or out. Any questions just ask. Thank you for your Sub Chris. Let us know how this works out. Ride Safe and have a Great Day.
@@TwoWheelRocco 10-4, thank you. I will get back to you when I give it a try
Hello, I’m a bit confused, all the manuals and info on the net show a 42 pilot and 185 main stock from factory (except 04 where they used 180) talking about 1200xl.. you say it’s a 45? so sure enough i had a 42 and a 185 inside, so should i go with the 45 or 48?? i have the same high performance show here and straigh pipes added
@@kspocketngroove3973 45 is typical idle nettle used I believe. Make sure your idle is set properly, with the idle screw. Not too high or low. Should be about 1000rpm. Twr has a good video on it. That was my problem the entire time. Someone had it idled really low, potato 🥔 potato 🥔 😂
@@SportyRider thanks Chris!!
Great minds think alike. As i mentioned two days ago. The guy prior changed the exhaust to Vance Hines . It also had a rough start and it spit a lot. I went ahead and up'ed the idle jet from a 45/190 to a 48/190. Left the main jet at 190. Wow! It starts on a dime. Choke not needed. But I was always a creature of habit. I would pull the choke out prior to starting. After the jet changed up to 48. Started much cleaner and it sounds great!. What method do you use to measure desired idle speed? I'd like to set it for 800-1000 Rpm but I do it by ear. My 2003 FXST does not have tach. Thus I do the ear test. One other question: When did HD start putting over flow drain on the bowl? My 2003 does not have this. Unfortunately, the gas then goes into crankcase. Do they have replacement bowl for the HD CV carburetor with the over flow drain?
thanks,
Happy to Help, I do RPMs by sound. As for the float bowl over flow hose built into the float bowl. Thats a Sportster thing. You can switch those Harley CV carburetor bowls. Hope this helps. Thank you for your Support. Any questions just ask.
I have the same issue. When I press on that quarter throttle I’ll get a cough, popping noise from within the carburetor. I’ll also get some hesitation. I’m going to look at the Jets to see if they never changed them and kept them at stock. Rocco, I also had the throttle stick on me. One time was scary because it was revving high and I literally had to hit the kill switch for the bike to turn off because it didn’t want to roll back. My understanding is that there’s a screw or nut that is closer to the carb body by where the two throttle cables meet. Apparently, that has to be adjusted. Have you ever experienced this happening and if so, what do you recommend?
Happy to help. If you look at your throttle underneath, There's a small wheel loosen that all the way that's what's interfering with your return or the cable. is too tight on the adjustment at the throttle that's where it all happens. I'll send a video. Thank you for watching and you sub Jose. Ride safe and have a great day. ruclips.net/video/kiYfRxvdxAg/видео.html
You said just ask so I'm gonna:) I've got an 1340 Evo motor with stage 1 along with Andrews 27 cam paired with thunder header 2 into 1 exhaust. I've got a large flat spot in torque curve. What's your suggestion on jet numbers. Everything else is stock
Happy to help. You failed to say what Carburator so I'm gonna take it for granted is a CV stock carburetor 45 idol 195 Main 3 washers under the needle. 1 3/4 turns out on air/ fuel. Let us know what that does. Thank you for watching and your sub Brian. Ride Safe and Have a great day.
92 heritage Softail classic
Just did the advice you gave me:) WHAT A DIFFERENCE!! I've got power now. No more torque dip whatsoever!! Thank you so much
Mine pops around 41 mph. It runs ok but hit 41 and it pops like it’s missing. Somebody put Vance and Hines on my bike before I bought it. Could this fix be my problem
Happy to help. I would put washers under the needle to change the fuel curve. I recommend three washes. I'll send you a video on that float needle adjustment. Popping is a lean condition. This will richen up your fuel curve. Thank you for watching and all your support Lee. Ride safe and have a great day.

@@billmeloche4918 Happy to help. I would start by checking the Petcock vacuum. This is how your engine gets the fuel it needs to run right. Diaphragm's fail. This causes lots of problems. ends up with none running bike. .I will send a video on how to test it. .ruclips.net/video/7Fo9Q93OJXI/видео.html. Take a look at your air filter, Make sure it is clean.

Can you do a video that shows how to adjust the float level
You should never have to adjust the flow level. All you are doing is compensating for another problem. They are presets. Back in the day they were brass tabs. Your problem lies elsewhere what is it doing that you don't like?
@@TwoWheelRocco Completely user error I accidentally pressed the float down a little too much not realizing what I was doing (was side tracked by my dog and didnt notice I was pressing it down) and I made it go a little out of adjustment. Not alot but alittle. And before I close up the carb offically Just wana make it right again.
@@codybatman7974 On the float, is a vinyl tab that can flex. I doubt very much that you altered its position. I would put it back together and see how she runs. Let us know how that works out.
@@TwoWheelRocco sounds good. Thank you so much. I learned it out of adjustment when I used the float measurement tool. Rear Part if it failed by 2 mm. And figured I did that mistake when I compressed it. Thank you so much for your replies ^_^ illnlwt ya know how she runs

Happy to Help, What jet are you running?. Thank You for watching and your sub ED. Ride Safe and have a great day
Hello Rocco, what would you do for an XL 1200R as far as jetting. It has stage 1 pipes and an air cleaner. What do you think about the cv performance parts, namely the acceleration pump nozzle?
Happy to help. Keep in mind these are cruisers. If you want to fool around with the Excelerator pump, nozzle, tune and test ride. Thank you for watching and all your support Bob. Let us know how it works. I try not to fix things that are not broke. Ride safe and have a great day, how's your bike run?
@TwoWheelRocco well I'm not sure at the moment. Have a family friend going through the carb bought a all balls re build kit and cv performance kit, which includes a different needle similar to your washer trick. He said it's idling at 800rpm... seems low but I'm not sure. It was stalling and coughing. I believe the 1200r has a longer duration cam than the other 1200's. Would that change your mind on jetting. I don't want to hate my bike that's why I haven't touched it myself as far as motor work I don't have much experience with it and I just want to ride my bike not get frustrated and worried I have it less than ideal
Ohh it also includes a shorter accelerator pump nozzle and ez adjust screws
@@bobfabian2161 if you need, higher the idle. ride your bike and then let me know what it's doing. They are easy bikes to work on. Don't make it over complicated. It's a cruiser. Ride safe and have a great day. The cam will make minimal difference. I love the R models with a dual calipers and there nice paint. And yes, the cam in those motors are a little different.
Sounds good, how does it run?
Heyy, I’ve got a 1200 sportster had screaming eagle pipe in originally and I’ve swapped them to Vance and Hines short shots and I’ve got a rough idle any recommendations
Did you re-jet your Sportster? What jets were in your Bike?
Two Wheel Rocco I’ve just pulled the bowl off and I’ve got a 42-170
Go with the 48 pilot. 185 main. Turn A/F out 2 turns. Let us know how that works out. Thank you for your Sub Armiger. Ride Safe and have a great day.
Ok I’ll give it a go I’ll order a spread of jets thank you
Any questions just ask,
Rocco, thanks much for all your fantastic videos.
I do have a question about my new-to-me 1996 XL1200C with only 3700 miles. Previous owner installed old style Screamin Eagle 1 mufflers. Bike has stock air cleaner. I took apart the carb and found 170 main jet (stock?), 45 pilot, mixture at 2-1/4 turns, 3 washers under the needle. I’m replacing the air cleaner with Screamin Eagle. What is your suggestion for carb setup?
Start with a 185 main. Then test..If you like it, then adjust A/F screw... With the new intake you might have to go with the 48 idle jet. Let us know how it works out. Thank you for watching and your sub Kramer. Ride safe and have a great day test and tune. Hope this helps.
@@TwoWheelRocco Thanks for the quick reply - I’ll give it a shot!
Hi Rocco, I’m getting deceleration popping, so before anything I went 2-1/2 turns mixture with no improvement. Then installed 48 idle jet and it still pops. Then installed 185 main jet. Bike starts and runs great, but still popping on decel. Any thoughts? Thanks!
@@kramer2965 I like 1 3/4 turns on the air/ fuel. With 2 1/2 turns you're making up for a vacuum leak which is causing a lien condition and that's why you need to open your air fuel screw to 2 1/2. But you sacrifices on deceleration it can't burn that gas. Test and tune find out where that vacuum leak is. that's what I would do and let us know how it works out. It takes time test and tune.
Thanks much for your insights Rocco
I have a 2004 HD xl883c when I get to about 75 I feel the engine almost like skip a beat just for a split second any ideas what that could be? Under 75 runs smoother and over 80 same thing
Take a look at the vacuum hose that's connects to the Petcock, Sounds like it might collapse for a moment and cause a gas problem. Let us know how it works out. Thank you for watching and your sub Edgar. Ride safe and have a great day.

How do you tell jet size
Happy to help. There will be numbers printed in the top of the jet. Some Chinese jets, which are cheap knock offs might not have it. Nine out of 10 do you have it.. Thank you for watching all your support ethanpike.. Ride safe. Have a great day.
Hey rocco, need some help. I have a 01 883. Think it might have the same screaming eagle intake but my problem is it's straight piped and does not like to start without the choke on. Point blank even on a 70° day. Only starts after it's been ran. Backfires like crazy when idles down and almost hiccups when idling sometimes. I think it was never jetted but I'm not sure. If it wasn't what jet setup should I run because it doesn't have slip ons and the intake.
you need to take a look at what jets you're running on that 883 Idle and Main. And how many turns out on your air fuel screw. Let us know. Happy to Help
Looks like I got a 42 pilot,160 main. Air fuel screw is 3 turns out had it at 2 turns out and she was getting really hot. Any help is appreciated
@@coybeaman9724I would go 45 Idle 170 Main... air idle screw 1 3/4 to see what difference that makes. Should cool it down. Let us know how it works out.
Hey sir how's it going? I had a question regarding my 01 Sportser XLH 883. I replaced the ignition coil, spark plugs, plug wires, got a new starter relay, battery, all the fuses are good. She was working fine, then all of a sudden she cranks but dosent start. I'm not getting any spark from her, any idea what it could be? Thank you again

Happy to hear all is well Chris. And thank you for all your support.
How do I know what sized jets to put in a carb? Or rather how to tell what is running right, not to lean or rich.
What bike, year, air filter and pipe?
@@TwoWheelRocco 1998 sportster 1200, slip on screaming eagles and a arlen ness big sucker intake. Is there a chart or way to figure it out for other mods to other bikes?
Dude where is your shop located. I think I'm having the same issues with my vtx 1300. The guy I bought it from put Vance and Hines exhaust and modded the air box. Runs great when moving but warming up and low gear not so much.
Happy to help, Located Treasure Coast Fl. If you have any question just ask. Thank you for your Sub BK. Ride Safe, Have a Great Day.
The screws are Japanese which means they aren't actually Phillips head, they are JIS (Japanese Industrial Standard) head which is better than Phillips. If you compare the two heads side-by-side, you will see a tiny "x" inside the "+" with a deeper hole for a better bite with a JIS screwdriver or bit. If you force a Phillips head into this too hard, you will strip the head. (Ask me how I know.) My Mazda Miata had these screws everywhere in the body and the engine. You can get the JIS screwdrivers on Amazon, eBay or anywhere for just a few bucks. They work much better than an impact driver.
I'm not criticizing because I think these videos are excellent; just offering info which helped me a bunch. I learned the hard way.
Thank you Rocco for your knowledge. I have a 06 custom xl 1200 sportster with Vance and Hines short shots and a A/N big air sucker air intake, for some reason when i let off throttle i get back fire or if i set at a stop light and sap the throttle i get a pop from the carburetor. The bike seems to run fine no loss of power just back fire and poping. Do you think it could be the jets im unsure if they have been changed. Thank you very much for your help and thank you for the great videos you are a great help.
My 96 Sportster with slip ons and a small open intake, has those idle and low throttle carb hiccups. I’m a new owner of it so I don’t know what jetting. Will adjusting this screw help things until i can get to jetting if necessary? Thanks!

i know this video is old BUT I NEED HELP! i put a new breather on mine. its pretty much open air flow with a fliter to stop junk from getting in the carb. but i did not re jet the carb. but it idles good, but when i start to add a bit of throttle, it boggs down and black smoke starts chooching out the tale pipes. until i go a bit past that point in the throttle, and then it revs right up...i bought a set of new gets for both idel and slow flow. they will be here in a week. BUT WHY IS IS ACTING LIKE ITS GETTING TO MUCH GAS and BLOWING BLACK SMOKE? if anything it should be running super lean. the air gas is set at 1.5 turns, it was at 2.5 and was still doing the same thing.
Happy to help. The first thing I would check is your Petcock, I will send you a video on how to test. Sometimes the diaphragm in your vacuum operated. petcock fails and this allows too much fuel to get into your system and your motor will run very rich. Any questions just ask.

Update...changed the Main jet from 185 to 190 with the 45 pilot - went to 2 3/4 turns a/f screw. This really smoothed out the throttle...Thanks again Bill M

Hey Rocco, i have my first motorcycle ever and its an 06 sportster xl1200l cv-40 carb. I put 13,000 miles on it last summer and its not running right. I noticed my rear jug was spitting oil into my breather bolt so i put a catch can on it. It isnt helping. Ive watched all your videos but i dont know which one to do. Can you help an old man out?
Happy to help. Sportsters just don't like to be overfilled with oil. Check dipstick with the bike, standing straight up. Oil level just to the halfway point of the two marks, and the bike will run its best and don't spew oil into your system. Thank you for watching and all your support Mickey.

Hey, very helpful video! I just bought a 03 883 and the guy said it had a 1200 kit in it. it runs like junk and won't idle or even rev. when I try to give it throttle, some compressed gas comes out of the carb, and it spits out the carb. I took the carb off today, and it was 3 and 1/4 turns out. Any recommendations? What jets should I buy it its truly a 1200 kit? thanks!
it also has the same air box as yours but is basically straight piped

@@TwoWheelRocco hey thank you! I just found out that they’re 48 and 170 jets

Need your advice. Bought a new throttle control for my panhead my old one has a nylon sleeve the new one is metal. Should I use some grease on the handlebar so new throttle isn't metal on steel? Thanks!
I would use some grease just to dampen any vibration. Thank you for watching and yourself Miguel. Ride safe and have a great day.
@@TwoWheelRocco Perfect Thanks & Ride Safe brother💙
Rocco, thanks for your videos. I have a 98 xlc883 with k&n and drilled stock mufflers. With a 42 and 160 main i think the bike is very lean. The drilled pipes have very little snap/pep and only make power when the bike is shouting loudly. The mix screw is 3.5 out and the bike still stumbles when you blip the throttle warm.
I am in the belief a rejet to 45 and 175-180 will help, but the drag pipes are always going to rob my low end.
Do you believe in lollipops/insert baffles or do you recommend a slip on that can help get my low end power back?
Happy to help I believe the 45 and the 175 or 180 is the way to go. Get a set of slip on and turn your air fuel screw down to one and three-quarter out. Then test/ tune. Thank you for watching and all your support. Any questions just ask. Ride safe and have a great day.
Difference between SPITTING and SPUTTERING please.
Happy to help. All the same problems, I find spitting and sputtering is usually a lean running motorcycle. Your gas mixture is wrong. Hope that helps. Thank you for watching and all your support. Vic. Ride safe and have a great day. Any questions please ask. Most important is to find out what jets are in that carburetor. They're relatively easy carburetors most times they get vacuum leaks and that's what makes for all the problems. that's my opinion. Rich Fuel is always accompanied by foul plugs and black smoke.Have a great day.
Hey rocco,
I have an 89 XL1200 European model. The carb doesn’t have the accelerator pump. Do you happen to know the stock jetting for these models?
I now have a 200 main and a 38 idle jet installed. Came from a 42 where it wouldn’t come off idle nicely. The bike is completely stock. It now runs just fine, but in 4th gear at a slight uphill it coughes into the carb. At a standstill and in lower gears it runs just fine. Idle-screw is 2-1/4 turns out. Any idea how many turns I can go out before I have to use the larger pilot jet?
Thank you for your help!
Sorry, I'm not that familiar with those carburetors. Thank you for watching and all your support. You will have to test and tune, see what works but fifth gear is wide open to a point, so I wouldn't expect much. Enjoy your ride. Let us know how it works out. Ride safe and have a great day.
17m27s mark the jet that spray gas in carb what one is that? Mine aint spraying. I took off couldnt blow thru it but could get suction.

@@TwoWheelRocco ok thanks
Hey Rocco, I rejetted my 883 with a 44/170 and turned out the mixture screw 2 turns. Bike runs great and will only spit once in a blue moon, but has a lot of decel pop when I get on it and let off. Could this mean it could use a little more on the mixture screw, or up the pilot jet to a 45? Thanks Rocco.
What pipe are you running an air filter?
@@TwoWheelRocco running the Emgo slip-ons and a K&N air filter. Its the stock air cleaner just with a K&N "high flow" air filter.

This is such a good video. Thank you. I’m hoping to get some advice. I have a 99 sportster 883 and I just ordered v&h short shots and an s&s air intake. What jets should I order? Any input would be really helpful. Thanks for your time and the great video.

....prior owner replaced the exhaust system and now she's hesitate and black smoke when acceleration!!!

Do you brush off the accelerator squitter - can you use throttle body cleaner)? I haven't changed my jets yet...I'm from Canada...I saw some "Threads on google) " that say the jets are smaller(42/170)??? So should I see what sizes are on my 1200...ie: if the slow jet is 42 - go up to 45/ or right to 48? If the main jet is 170? go up 180? or right to 185 ( I have screaming eagle slip on, and just a K&N filter - no high performance breather body)Right now I get a hesitation sometime when I rev match gearing down...I love your videos...very informative...Hope this makes sense to you - you are my Guru Thanks in Advance Rocco...I really appreciate you knowledge

Rocco I replaced the idle mixture with an after market easyadjust screw, and the carb started poppin : I removed it and put the old one back, Still ain't running right . could the seat be damaged and if so whats the verdict . Thanks Roc.
Remove and replace the air fuel O-ring. With a new one. Sounds like it was damaged. Little rubber washer is small. Easy to lose easy to drop . Just be conscious of it and you should be all right let us know how it works out.
Thankyou rocco, but its a new O ring, could that after market idle adjust have widened the seat ?
@@nickruopoli8720 I don't think so Nick. Did the old O-ring and washer come out when you removed the original one. I would take a look at some of your vacuum lines maybe you disrupted or cracked. Compare the two ends to see that they were the same. Take a close look because it appears that it's not seating properly if all your hoses are intact. Let us know how it works out.
Rocco, I backed fuel/mix screw out, and had a hell of a time pulling the washer out ; it looks like it off round so the screw could only seat up to that point ; can't figure how that happened, anyway ordered new set up. i'll let you know what happens.@@TwoWheelRocco

Hi Rocco.
I’ve watch many of your videos and love them. However I’ve neve see one with acceleration adjustment. I cleaned the carb like you teach me but I can’t adjust to work slow. When I stop, the acceleration stays fast/hight. What should I do? Thank you.
