Nice work! That homemade bumper may have to go to be a $4500 YFZ, however. Haha
Not in todays crazy ass market. I’ve been selling some turds for way up there.
@@Anticidal25901 such as?🤔🤯🤔
For sure lol that bumber looks horrible
@@craigmorgan4676 such as the lies he spews as they all do
I'd repack that exhaust. That packing is probably jacked from burning all that oil
Yeah maybe he could put all the Drawers back in the carburetor as well. And the spark plug is missing its Sunday bowtie
Very well done on that one. You stuck with it and saved it. Way to go Joe !!
Already know this is gonna be a Great video Joe!!
Joe mama
If its coming from the over flow then it may have been working out the bubbles in the system and may have been over filled. So that may not be an issue.
Can't go wrong w/YFZ450s! Nice work.
Awesome brother love the rebuilds you do very cool
NICE JOB!! I live in Oregon, todays market where I live 5k to 5,500k for the YFZ450, our market has blowing up the past 3 years everything from SXS quads dirt bikes have skyrocketed to a all time high. Everyone wants to ride the sand. Dunes now and take advantage of our awesome riding we have here in Oregon. Our sand dunes are the best in the USA..
Backfire is usually a sign of lean yellow flame shooting out is usually to rich but I've had issue with popping just from needing a new exhaust gasket or headpipe not being tight enough
You need to go back to factory jeting , and then tune idle and tip-in with adjustment screws. And then jet for your pipe later.
Also it looks like to me one of them intake valves was sitting lower than the other two.
I think there is something funky with that carb,the fact that it came with two has me suspicious.
lol why really dude.it don't matter he won't own it for long it will sell
Hey Awsome video man been watching since day 1 every morning before school or after love the videos as always keep up the good work
For the backfires it may leak the exaust from somewhere and the jets maybe its ok(sorry for my english i'm mechanic from grecce keep the good job)
Yup maybe dropping the needle a few clicks since it is running a little lean, or checking for the header nuts they often get loosen after to many times being taken apart or overtightening them makes them come loose, if so try double nuts so they dont move.
@@alfredorodriguez4539 i didn't hear anymore backfire when he was riding I guess it fix
Seeing you post a video is always a highlight of my day
Same m8. Always look forward to a new video
me too its currently 3am i watch them before bed :)
nice job lad well done
Nice rebuild!
Awesome Job.
Got the lean pop on decel, valves are loose too that ticking would shit me.
Definately doesn’t sound right.
I would go back to oem carb specs and start again.
It’s only got a slip on so shouldn’t be hard to get right
Love the Raptor series quads, that 450 is almost as spunky as the 660r. Mine is now a 686 stroker and fast as hell.
Another awesome video!
Another one saved 👍🏼👍🏼
When you pull aluminum bass apart and then your retighten it retorque it it moves around when it gets hot then cold and receipts you got to understand how luminum works with cold temperatures in hot temperatures it moves around a lot and it's got to reseed itself and you have to retorque all them bolts
Leaking coolant because you need to change wather pump selas, I have a same problem. Nice video
Nice man!!
outstainding info ..ty so much
Sounds like a vacuum leak between carb and intake spray card cleaner around there see if reves go up.
Back Fire me coust by the carb choke had the same issue with mine
Sticker:
Heat gun & plastic razor blades.heat gun shines up plastics nice.
nice work
its a good looking quad for sure. plus, Yamaha is the only sport quad maker currently so all YFZs are popular/valuable right now. Ya, I agree, 4500 for sure. Thanks again for another sweet vid and as always, be safe my friend :)
Try adjusting the fuel screw bet it cleans the poping up should of done that before messing with the jetting
Wiesco makes pro X
I change that exhaust back to stock that might fix your jetting issue and also if you listen to the video there's a slight tap
Great job joe sounds brilliant don't no where all the negative comments come from I think you've done an awesome job on this and yeah it is worth the money take care mate and all the best 🔧🔧👍👌🔧
There should be holes in the carrier bearing housing on the sprocket side i use a nut driver that fits in the hole through the sprocket spokes then rock the quad forward or back using the force of the sprocket bumping the nut driver to adjust the chain so not to scuff up or to avoid beating on a screwdriver its easier especially if its stuck in place and needs persuaded. I had my water pump seal leak after fresh rebuild 1 time and that was it weirdest thing. Just a thought on the decel backfire I had a aftermarket pipe that was not perfectly round at the head where it mounts and wasn't getting a good seal at the gasket ended up shaving it down on the hi spots so it seated to seal up decel pop went away.
Was coming into the comments to comment this but you beat me too it
2:46 🥰👌👌
Wow man that is my dream quad 🔥🔥 loving it 🔥🔥🔥
Just a test but that exhaust maybe causing the backfires. try your other yfz\s exhaurst if it runs betting pickup a pipe or silencer for replacment. JUST FYI
Good 2 see u started lapping valves. Easy step while u have it apart. A lil added insurance
Check bolt tightness during initial brake in period.
Ill bet ur so glad its done for most part and just ready to flip it n forget,been some real headaches and issues for you.but its turned out nice despite that questionable head.nice!!!snooky pa.🤟
Idles perfect to me.
I wanna see some old 2 stroke dirtbikes! Mostly CRs.
All these mechanic’s in the comments but don’t even have a RUclips channel anywhere near as good as this guys. Keep up the work and doing you!
I was thinking the exact same thing. This dude is helping thousands of people learn engine repair stuff and just because there are one or 2 thibgs he night do that some "pros" may disagree withn they shit on him. This channel is amazing.
Yea man last video I threw it out there to Hone the vales I can't wait to watch this one
Have you tried adjusting the fuel screw I had a similar problem wirh a backfire and the fuel screw adjustment was the fix...
You have to change your water pump shaft. It had some scoring we could see in the previous videos. Mine had the same issue, any minor scoring causes it to leak past the weep hole. I had changed mine to an aliexpress one, it got scored again after some rough motocross track riding.. i think i will purchase an OEM one and try again.
Yea I had to do the same on my cr80
Kenny Roberts colours ftw
Amazing
its going to ring seize!!!!
Good shit bro! I love your videos. Did you ever put in an oiled air filter? No air filter will cause it to lean out and backfire. It's real close to being 100%
Bumper gotta go ASAP lol
check the slider for the THROTTLE VALVE PLATE, a lot of people put that upside down, the part with a small hole goes down, put a pilot jet #50 and the mixture screw to 3 turns, maybe you have to drill a copper cap that is covering the mixture screw, Use a 5/32 drill bit to drill the copper cap that covers the mixing screw, do the Zip Tie Mod to the acceleration pump, change the needle to NCVQ and put the clip in the fourth position
if you have another yfz450 with the same carb, switch it to see what happens
Nice quad
It is a nice quad
My son same thing about wiesco piston. He hates them so on my 2010 kx85 I went with prox high compression piston too
Yellow grips would be sickkk
What’s that tool called you used for the valve seat width
It sounds like the CDI isn't advancing spark upon increase of throttle / engine speed.. Might be why backfiring
Are there any cracks on the intake boot.
Try changing the muffler packing for the backfire
Insane quad🔥 I hope you will build a 250 or 450 sometime in the future like crf, kxf, rmz or yzf! Would be cool to see those bikes on the channel!
What I have done when I ordered the piston that was tight like that I actually just slight ran the hone it the cylinder it really didn’t change the gap but made for smoother cylinder surface and better compression
I did that instead of filing the rings
I was thinking this
Great vids bro I hope you can find a suzuki ltr450 next and we can run them against the other 450s for comparison
I've been having trouble with a raptor 660r dual carb tuning
New sub .bro I'm really liking ur clips so far dude I'm gna have to back track and catch up 👍👍
Really should have had new sprockets with the chain they are badly worn. Is the backfire an over fueling issue as it's normally unburnt fuel in the exhaust unless the timing is slightly out somehow
Could be still running lean. Start it and rev it up and pull the choke out to see if it still backfires.
Good job bro but usually me when I tighten a chain I put it tight cuz it'll loosen up right away that's still loose I put it tight tight
Backfiring is usually related to a timing issue.
What’s the tolerance for the piston on average for most engines of each manufacturer (Honda, Yamaha Kawasaki etc.?
Nice job man! Only think I can say is you put your masterlink clip on the wrong way the round end (closed part) should facing the direction of orientation to prevent the clip being knocked off
lol yeah ok Mr. expert.
@@funtyes1970 my qualifications would say so yes thanks 😁🖕
You got to have a better front push bar laying around that thing needs to go and will improve the value some .
look for small exhaust leak may be sucking in cold air and maybe change the plug
Hi back fire is almost for sure because its a little Lean on the jetting not much But a little Nice work man
That type of exhaust when you downshift and let off the throttle it will backfire like that or let off the throttle it is OK make sure the fan works
If the valves were leaking the vaporlocking effect from the leaking headgasket may have bent the valves?
i have that same exhaust on my 03 kfx434
It's pretty nice!
I’ve been trying to figure out the wiring on my raptor 350 and I guess I did something wrong because when I connect the battery the start automatically starts going? Any tips
A bit snug is good just not jamming tight. Gonna run like a beast.
I liked that atv
Isn't that outer water pump seal in backwards? Great video keep up the good work. ✌
They are called keepers.
That popping is most likely from the exhaust
Maybe the backfire issue is caused by a small air leak in exhaust front pipe .
What happens if you have very little ring gap?
I believe the silencer is rotted out change to silencer
Do you know how to titen valves on the 400ex
Where do you get those
Those quads are lemons . but when there brand new and mint there a beast ..just to many problems ..everything has to be perfect
Beautiful quad and again killer video man you have some of the best build/fix videos on RUclips I’ve been watching and subbed for almost 4 years now and haven’t missed a video yet great job man you give sabo a run for his money
@Whoop!
NIIIICE 🔥👍✌️
The transmission is already broke in you could shift if you wanted to
My drz125 is having the same problem with the backfiring I don’t know what it is tho I cleaned the carb and made sure the valves were in spec and still it backfires. If anyone could help it’s a 2021 it just randomly started happening it has good spark and gets good fuel flow.
Joe I just bought same bike as this
At night I notice the header pipe is glowing orange . I checked the plug and it doesn't appear to be running lean. Any ideas ?? I need to check the jets probably?
honestly brother you should lap those valves until the noise when grinding is little to none
If you have a manual for it it will tell you what to jet it for your elivation
ALL HELP APPRECIATED
(03 yz125) Can anyone help me figure out why my bike isnt getting fuel through my carb... I did a full rebuild on it, float moves freely and i set it to where it needs to be, and she still doesnt get fuel through the carb. When I spray into the carb it kicks.
Also it leaks fuel from the front of the engine block looks to be a seal problem. (compression is fine)
I don’t know about a 4500$ quad. Like 3-3500$
