piston and ring size?
OK I have a leaky gasket on my front cylinder. I put some Bar's stop leak in it and it worked pretty well. Anyway after I (hopefully) get through the rest of this riding season I'm doing a tear down and rebuild and a bunch of custom stuff to the bike over the winter.
While I was looking at parts breakdowns I saw that there are 3 different piston sizes and three corresponding ring sets listed. Anyone here know why? I figured they might be for use after a cylinder sleeve re-bore but it doesn't give bore sizes and I'm kinda skeptical that those little sleeves have enough meat on the walls to even bore out. But, I havent seen them so I'm ready to be wrong.
Bike is a 99 with 36000 miles on it so the list of parts to replace is getting pretty long. The last thing I want to do is tear this thing down and only replace the gaskets and then have some old worn part break after putting it back together.
Anyway, any info anyone has on these 3 piston and ring sizes would be greatly appreciated.
BTW first small engine rebuild. All my experience is automotive/heavy duty.
