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
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
Very well done on that one. You stuck with it and saved it. Way to go Joe !!
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
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.
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
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 :)
Sounds like a vacuum leak between carb and intake spray card cleaner around there see if reves go up.
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
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..
Leaking coolant because you need to change wather pump selas, I have a same problem. Nice video
Wiesco makes pro X
All these mechanic’s in the comments but don’t even have a TH-cam 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.
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
Already know this is gonna be a Great video Joe!!
Joe mama
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
Try adjusting the fuel screw bet it cleans the poping up should of done that before messing with the jetting
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.
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 😁🖕
its going to ring seize!!!!
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
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 🔧🔧👍👌🔧
Yea man last video I threw it out there to Hone the vales I can't wait to watch this one
I wanna see some old 2 stroke dirtbikes! Mostly CRs.
Kenny Roberts colours ftw
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
Yellow grips would be sickkk
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 :)
Love the Raptor series quads, that 450 is almost as spunky as the 660r. Mine is now a 686 stroker and fast as hell.
Sticker:
Heat gun & plastic razor blades.heat gun shines up plastics nice.
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
"Ive been hearing bad things about wiseco lately" proceeds to pull pro x piston out ...."whys it so tight in there" thats what she said .... Second guesses himself . shoulda bought a wiseco lololol
Ya know what's really funny.... Wiseco makes ProX!!! It's the same company in the same foundry.
Pops
It sounds like the CDI isn't advancing spark upon increase of throttle / engine speed.. Might be why backfiring
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!
Back Fire me coust by the carb choke had the same issue with mine
What’s that tool called you used for the valve seat width
Beautiful quad and again killer video man you have some of the best build/fix videos on TH-cam 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
Maybe the backfire issue is caused by a small air leak in exhaust front pipe .
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)
Dude use a flex hone 320 grit there made for honing nickesil cylinders
Ya watching him rebuild it no hone or new cylinder bolts they have degrees for a reason to stretch old ones are already stretched
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
Sounded like your axle is bent went you went down the road
One tires was off the bead I noticed
@@2vintage much better than replacing the axle 👌🏼
Check bolt tightness during initial brake in period.
They are called keepers.
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
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
I think with some new tires and the idling issues and leaks fixed it be worth 3500
Nah, heads ticking like crazy. It’s boutta go.
nice job lad well done
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
2:46 🥰👌👌
That popping is most likely from the exhaust
The transmission is already broke in you could shift if you wanted to
Awesome brother love the rebuilds you do very cool
i have that same exhaust on my 03 kfx434
It's pretty nice!
Good 2 see u started lapping valves. Easy step while u have it apart. A lil added insurance
Bumper gotta go ASAP lol
Well you just answered my question if I would have continued watching
FFS Joe did you really only do 2 of the 5 valves also it is the inlet valve seals that can cause smoking issues not exhaust Pistons are oval and tapered so clearance is mesured at bottom of skirt 90 degrees to the pin also do not set ring gaps in line with major and minor thrust faces that pushes the gap ends harder against the bore a little education on basic principles goes a long way !! also backfiring on overrun is caused by the header pipe sucking air at the head or muffler joint DONT BE LAZY!!!!
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%
Can't go wrong w/YFZ450s! Nice work.
Always change your sprockets when putting on a new chian otherwise its pointless it just restreach to the old shitty chain good vid tho keep it up
The more it gets broken in the better it will run. I was hoping you did a rip down the road.
He did . lol u ended the video to soon my g
Another one saved 👍🏼👍🏼
Nice rebuild!
24:40 That thing has a loud tick how can you not notice it?
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.🤟
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
I've been having trouble with a raptor 660r dual carb tuning
I believe the silencer is rotted out change to silencer
Are there any cracks on the intake boot.
Try changing the muffler packing for the backfire
outstainding info ..ty so much
New sub .bro I'm really liking ur clips so far dude I'm gna have to back track and catch up 👍👍
Metal to metal on the piston and cylinder haha lol errr
Could be still running lean. Start it and rev it up and pull the choke out to see if it still backfires.
I didn't see a rod bearing when you put the piston on
A bit snug is good just not jamming tight. Gonna run like a beast.
New piston and rings. You have to hone that cylinder. You can hone a nikacil cylinder bro. Its so hard the hones barely even leave a cross hatch. But its good enough to seat the rings. That glazed cylinder is going to screw you
If the valves were leaking the vaporlocking effect from the leaking headgasket may have bent the valves?
nice work
Wiseco piston company's been out for a long time that's the first I've hear you say you hearing bad things wow
lap the valve after you abraid the valve seat.
Wish I had your lucky finding a yfz450 for $1400
I don't think you should have lapped those valves ... they are titanium and all you did was remove the coating. You should have just lightly, fine wire wheeled them, to just remove the carbon build up. I hope it works out for you ...
well seem like it is. and seem like he knows what he doing he get them running every time I think he pretty good mechanic
@@funtyes1970 he doesnt. He makes loads of mistakes every single video. But i respect him for trying. But you watch a video where the ATV runs for an hour all together maybe and you ignore the advice of someone who very clearly knows more than you?
@@krotchlickmeugh627 I don't know seem like he is doing something right with over 250k subs. compare to your 24 subs. lol
@@krotchlickmeugh627 and if he was doing so bad fixing them dirt bikes and ATV, he wouldn't be selling them. to me he is doing pretty good for himself just got a new house, sound like to me you are very salty for some reason
@@krotchlickmeugh627you think he reads all his comments and you also think he hasn’t learned from his comments considering he’ll ask his viewers questions? He also is like what 30 and still learning… there is more than one way of doing things… you’re way or the high way may work with your wife and kids but in the real world there are many proper way of doing things not just the way you learned…
It is a nice quad
Nice man!!
My son same thing about wiesco piston. He hates them so on my 2010 kx85 I went with prox high compression piston too
No backfire riding is good, it's under a load!
bro put a cp piston or wiseco, prox is trash
The backfiring is unspent gases, as long as you are on the gas it doesn’t pop its when you let of the throttle, any time we change the exhaust on our track bikes(sport bikes) it needs to get tuned or it pops like crazy, on my superduke ive seen the resonator can explode on the akra exhaust system, i could definitely be wrong but id say you have carb issues.
Just me or does that have a pretty loud ticking sound.
I was wondering the same tbh not hating or bagging on his work but I did notice it too
@@bobbyhill1176 Yea almost sounds like valve ticking or piston slap.
Those quads are lemons . but when there brand new and mint there a beast ..just to many problems ..everything has to be perfect
Backfiring is usually related to a timing issue.
Idles perfect to me.
Break it in it'll subside usually.
Hi back fire is almost for sure because its a little Lean on the jetting not much But a little Nice work man
The 06 needs a oil line added to the other side of the head. Yamaha fixed it on the 07.
I don’t know about a 4500$ quad. Like 3-3500$
I liked that atv
