on one hand.....
I need to make a decision about the direction I want to take as I modify a four stroke thumper. My bike, KLX 650R, has a nikasil jug. I can either overbore,and line the cylinder and get a big bore engine( and lose the coated cylinder), or I can get a
high compression piston and a stroker kit. What should I be looking at to help with the decision?
