[QUOTE="Eric Kropp, post: 1387664, member: 119385"] I would probably replace both seals and since you are that far in I would pop the top end and check the piston for any scoring and that pretty much forces you to replace the head and base gaskets, which can also suck air, 'specially the base gasket. I would check the carb mount for cracks(very likely). If the carb mount has cracks I would buy a new one if they are available and maybe a second one if you plan on keeping the bike. I would check e-bay for one to. They are very hard to come by for some older bikes like yours and mine(IT465). I have three for mine. Eric<>< [/QUOTE]
