Hey guys I have a red lion 2Ralg 79cc 4 stroke and the crankshaft seems to be 5/8 without a keyway, I really need a 3/4 in shaft q type. Any suggestions?
You can by a sleeve 3/4" to 5/8" with the key way cut into it, and also 3/16" by 1/4" key stock. Just find a machine shop and have a key way cut in your engine.
