okay im sure this is probably a repost or something but,
I am rebuilding the motor in my 400ex with a wiseco 426 11:1 piston and stage 2 hotcam. the kit also came with all the top end gaskets n such.

My question is what else do i need? ive been reading all over the internet of guys that are putting aftermarket carbs and jetting and all this stuff on there to go along with the 426. do i really need this or is it just a good idea? also what type of fuel will i need to run and how do i get it/ mix it?

thanks

Put a crf450 cam chain in it. Much better chain, and also cheaper.
