Does anyone know what would be entailed in rebuilding a 02 zr 500 into a zr 600 if it's possible? I was told the lower ends are the same. Obviously I will need 600 pistons and cylinders, and need to re-jet my carbs. Has anyone ever heard if this is possible or if anything else needs to be done? I have to replace 2 pistons and thought if the jets and cylinders were the only other extra costs, I figured I would try this. Any input? Thanks.
