Hello I just overhauled a 1994 xr100r for my neighbor. the bike jumped time because of chain and gear wear. I replaced the chain and both gears,crank gear had to be cut with a die grinder and then knocked off with a chisel. Installing the new gear had to be driven on with a punch,no keyway just a press fit.reassembled entire engine.started on first kick then had an awfull rattle and quit. no compression so I removed the valve cover and the cam was not turning,upon more investigating the crank gear was spinning on the shaft. will sleeve and bearing locktight hold this on or do you think it might need a little spot weld? There is nothing that tightens against the outside of the gear just a seal next to it.
