My yz450 died a horrible friction related death last week and I have to replace the rod, crank pin, crank bearing, cylinder, piston, rings, etc... I am thinking about making it a 502 :laugh: with their heavy stroker kit and a 2mm overbore. Keep in mind that I ride hare scrambles... I'm thinking the heavy crank will help me there and make it a very tractable and very powerful motor. Any thoughts?
