I took the 426 topend off today to put a crf cam chain in since it was getting noisy. Im going to have the head/valves done while its apart and also want to rering it.

Wheres the best place to get the rings its a wiseco. Do i need to get them directly from wiseco ?

i would that way you no your getting the right stuff or from trinity racing

you should be able to order the rings from anyone that carries wiseco as long as you know that you have a 426 for sure

I need to go pick up a mic or take it to the shop to be sure but im pretty sure its 88mm

I dont live far from wiseco and ill be there this monday anyway so ill probably just drop by w/ the piston and have them set me up w/ some rings

Thanks for the replies

Yes, its a 426 for sure. Unless you have rode it a bunch, it shouldn't need rings yet, although you do have that head off, so it wouldn't be much trouble. Cylinder looks good doesn't it.

ya the cylinder still looks good had some carbon buildup at the top where the rings dont ride but i cleaned it up. still had a some crosshatch visible. I figured while it was off might as well rering it.

Its a wiseco piston right?

Yes, wiseco 426 piston. I had the bore fit a tighter tolerance on the rings as well so thats why I was sure to tell you to let it warm up. Higher compression as well.
