LBC--Well, I prefer the PK80s to the GT5s personally. They have the shorter caged connecting rod and the lower wrist pin location on the piston. They allow for a smaller squish gap and more compression. Also, if you notice Duane can call his 69cc instead of 66cc, with a 40 stroke instead of 38 stroke. They are just better engines. Also, Duane checks them out before sending them out and uses decent bearings, plus, you got to respect a man who answers his own phone and is more than reasonable to work with. Watch these 2 videos from Fred at CRMachines that explains the differences:
