what piston rings are you guys running in your 125hp force engines? iver seen frank talk about 2 differant types of top rings and i am wondering what i should use for the motor.
I put a set of Wiseco forged pistons 4 years ago in my 1988 125HP motor that use the semi-keystone rings. So far so good. Compression has not changed at all since the initial break-in and the motor runs great.
