Non high compression pistons for 750GT

Post by rightsideup »

My GT is on the first oversize at the moment, compression readings seem low to me - 110psi rear and 100ish on the front. Should I be thinking of new pistons and the next oversize and if so, what recommendations for a 'normal' piston

Probably want to do a differential compression test first to determine valve as well as rings seal. Might save you a mort of work & $.
