Finally found the problem on '87 Indy Trail

I figured today I would pop the heads off and see what my troubles were. Last year it would move about 10 feet and bog down with no power at all. Well, today I found out the problem. It seems that the edge of the LH piston has broke away and chewed up the rest of the piston and head. When I checked pressure before I took it off, the LH had about 10 PSI and the RH had about 120.

Bad piston:


Good piston:
