In the process of rebuilding my 2000 426. Was looking forward to this video. Hopefully I can replicate your results. Thanks for taking the time to film the process
I'm trying to find a machine shop to rebuild the crank. Anyone find any? I tried some local places and they said no. Tried some online places and got no response
Damn this is looking dope nice job on the project been watching since you started re building engine inspired me to make a start on my yz450f 2005 engine getting the block back next Friday dropped them off for cerekote orderd a new transmission up so all been well will be nice and simple we will see
sick build man, popping off throttle could be lean pilot jet, could also be fuel screw isnt set properly. my 450 had a tiny bit of popping and i rejetted and spent some time playing with the fuel screw and the popping went away
Silencer for 03-05 yz450 which I used but it is out of stock right now: www.fmfracing.com/products/powercore-4-044222 You might have to just find it on ebay or something, I think that's what I had to do, because I think they stopped making them... Just look up: FMF 044222 I couldn't find the header anywhere and I think they stopped making them too.
The popping could either be the pilot, the ac pump squirt timing, or both. Believe it or not it could even be the needle clip position even though that controls more 1/2 to WOT
Out of curiosity; How much did the whole build cost you? Now finally seeing it finished, it may also be a brand new bike with customized powerparts... Not even the 426's on the pictures from Yamaha look this clean, god damn!

Respect for the build bro. You did great.
Motocross game changer. The bike that made 250 2 strokes cry 😅.
Nice work. Great editing. Good reference if ever needed for my 01 wr426 minus the bling. 😊
Full fmf exhaust pro taper handle bars gonna be nice I can’t wait!

Great work man
Damn that’s a sick build
I’m building 2000 yz426 have new weisco piston new jug, head everything ready to be put back together just waiting on a new crankshaft to come in

The popping just went away after the engine got broken in. It's got like 50 hrs on it now and runs great.
@@brodyfontenot awesome!
can i get a link to the exhaust please?

@@brodyfontenot thank you
Is that the stock tank or an aftermarket tank
Clarke desert tank with custom mounts

Looks odd with the 3rd gen plastics IMO but otherwise great job man
Looks good, about how much cerakote c did it take to do the frame?
I think it took like 6 or 7 oz.
Cool build! I'm just genuinely curious why you picked a carburetor model 426 to rebuild?
It has been my dads bike since 2002 so it meant a lot to keep it, wo we decided to build it.
@@brodyfontenot that's awesome!!
Did you put hot cams in this engine?
He did. It's in episode 14 of this build
Yes, but only on the exhaust for now, we might get the intake cam at some point.
I did this on my 01 recently so much nicer without having to use a decomp lever for starting

Thanks, I haven't figured out the cost yet... I'll probably do a whole video on it at some point.
