I have a 99 CR250 and have the potential to pick up a damaged 2000 Cylinder and head. My question is can the 2000 be mounted up to the 99 case with out any modifications.
Why? Just to see what the bigger bore would run like.
I would like to be able to swap cylinders without any mods other than jetting.
Sorry, I should have clarified that when the cylinderwas repaired repaired I would have an over bore kit done....267-300cc??? I'm not sure what available yet.
Check out Eric Gorr's website. There is some information on using different year model cylinders on a CR.
92 to 01 all will fit on the motor just differences in port size and timing.
