Turning This $1400 YFZ450 Into a $4500 Quad (COMPLETE TRANSFORMATION)

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..

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 :)

I'd repack that exhaust. That packing is probably jacked from burning all that oil

[@billybonewhacker]

Yeah maybe he could put all the Drawers back in the carburetor as well. And the spark plug is missing its Sunday bowtie

[@giwrgosdiesel7932]

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)

[@alfredorodriguez4539]

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.

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.

[@ralatgonzalez]

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

[@ralatgonzalez]

if you have another yfz450 with the same carb, switch it to see what happens

[@rico6249]

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!

[@CesarDRK]

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.

[@travisharvey883]

Yea I had to do the same on my cr80

[@ALDA2479]

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

Try adjusting the fuel screw bet it cleans the poping up should of done that before messing with the jetting

[@johnscovel3170]

[@acerig4675]

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.

[@george31380]

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.

[@scottallman9324]

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

[@PiazzaWoodWorks]

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

[@staind288]

It sounds like the CDI isn't advancing spark upon increase of throttle / engine speed.. Might be why backfiring

[@steveblottenberger1097]

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

[@jeffperdigao1820]

Sounds like a vacuum leak between carb and intake spray card cleaner around there see if reves go up.

[@MAD450r2]

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

[@trose7620]

A bit snug is good just not jamming tight. Gonna run like a beast.

[@Derekmoss82]

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

Good 2 see u started lapping valves. Easy step while u have it apart. A lil added insurance

[@moegreenbl]

Incorrect he just destroyed his valves they're over $100 a piece and they have to be matched fitted from a machine shop. You cannot lap titanium valves you take the coating off then the valve begins to wear extremely fast. Unless this was rebuilt before and those valves are stainless steel and I wasn't aware of that. That's what most people do when they're titanium valves wear out they put a heavier chain usually a stiffer spring and replace the valves with stainless.

[@patverry8926]

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!!!!

Do you have to divide the clearance by 2, because the clearance on the side you are measuring is maybe 0.003 inch but the other side is 0 at that moment (because you push the piston against the cylinder). Shouldn't there be 0.002 inches clearance on both sides at the same time?

[@Carl223]

Should be using telescopic bore gauges and micrometres for a lot of stuff he does. Not feeler gauges and clapped out digital vernier calipers.... The list goes on. But I agree. Clearance should be overall not pushed to one side. And even if he had feelers won't tell him if the piston and/or bore is out of round in spots. He makes enough money from flipping them and KZbin to not be using claw hammers and old sockets to drive seals in. But splurges on tooling in other areas. Strange cat.
