Default Re: Hello from California

In the video he says that the PK80s are 40 stroke and the GT5s are 38 stroke, this makes a difference. The 40 stroke ones all use the type "B" piston and the shorter connecting rod except the A80 and the half breed ones which are not very common. The GT5s use the longer connecting rod and are only 38 stroke.
