Will a 03 450 Flywheel fit on a 02 426?

I want to get a heavier flywheel from Trail Tech and they only have flywheels for 03-05 450s and I have a 02 426.

Will the 03 450 flywheel fit on my 02 426?

NO, it wont fit.

I had to buy the kit from Zip-Ty, and drill and tap the stock flywheel.

Did you have a hard time balancing it? How did you do it?

No, it didnt require any balencing.

Its is a machined product, so it should be true, but there mite be alittle mis balence but nothing noticable.

None of the WR flywheels will fit the YZ450/250... I know I've tried. A flywheel weight is the best answer for this,If its for bush riding I recommend the heaviest flywheel weight... 12oz... I got mine from Zip-Ty racing. It made the YZ soooooo much better in the forest... I also put a PowerNOW in,That also made Forest work better..... Now I wish I had the magic button also.... gghhrrrr.... My friend has a WR450 with the YZ plastic ( Front/Rear fender ) & he also put a YZ250F muffler on..... Its a great bike.
