I picked up a 1999 kx125 recently for a Splitfire PC build, only to find that the cylinder is totally shot.
Im having a difficult time finding a new cylinder to replace it with -
my question is - the service manual groups 99-02 kx125's, but its my (limited) knowledge that the cylinder and pistons are NOT interchangeable. Is this the case? I have found a few bikes being parted out for sale that have 2002 cylinders. Simply put, can I replace my 99 cylinder jug with a 2002 cylinder, then install a '02 piston?
Really appreciate any expertise here!
