Can somebody tell me the difference in pin location between 94mm "A" pistons and "B" pistons? I guess that that is the only diff between them.
Thanks |

the only difference I can note about A&B pistons, is the A are for 69-74 stroke, the B is for 78-84 stroke

A pistons have a wrist pin height of 39.6mm from wrist pin centerline to piston crown and Bs are 34mm.

It also looks like the skirt is shorter on the "B" piston.
Thanks everybody. |

I has to be shorter. As the crank stroke increases, the piston is pulled closer to the crank at bottom dead center and the piston needs to clear the crank cheeks/counter weights.
