Picked up an 81 GL500 project bike recently with a seized engine. Got the bike torn down and most of the engine torn apart. After cleaning the cylinder walls I was able to get her to turn over and I didnt notice any pitting in the cylinders walls. Bottom end of the engine looks good and internals all very clean. Am planning to just do a quick hone in the cylinders and rering the pistons. I pulled the oil pump today and managed to get one piston removed, but was not able to remove the other yet due to that damn clutch hub. Are there any tricks to removing that clutch hub nut, or is the special socket required? Where could I buy that socket if its absolutely needed? Anyone know a good place that I can pick up new piston rings and gasket sets?
