YZ 450 crank mod

4 posts in this topic

I ride a YZ426 and i noticed that the bore of the 426 is the same as the bore on the 450. They only differ in stroke. My question is this: can a 450 crank be installed in the 426 theoretically making a 450 dependant upon the height of the jug, cc's of the dome on the head, and, of course, the length of the piston. Anyone with any information please let me know. rwintyr@msn.com

thanks

Ditto . Falicon has the best set up cranks for our bikes. You are better off getting more stroke before over boring for a larger piston. The standard bike is way over bored for its stroke for ideal performance. :cry:
