i just picked it up and it needs to have the top end rebuilt. im looking for a high compression piston, and a nice clutch. also has anyone ported and polished the head? and maybe the valves? any help would be great im not looking to dump alot of money in to it but while its apart id like to upgrade.

also i heard that the rod and rod bearing are weak so if you up the compression the rod cant hadle it.

i run it with slightly modded and stock blasters so i need to keep up. any help with cheep mods would be great
