I am going to be doing some practice at the local track on my wr426f, and I was wondering if anyone knew what gearing to run inorder to compensate for the wr's wide ration gearbox??????? I basically want the overall gear ratio to be like a yz426. After all they are both five speeds, so it can be theoretically done. I'm thinking like 13/52 or somthing. I already have my bike set up exactly as a yz (tank, no lights, stripped everything down, yz timing etc) minus an 18 inch rear wheel. I know my wr/yz hybrid is up to the challenge!!!!! Help me out!
