Default Re: Curious about the engine, :question:

I only have the Dax crank. I bought it as a replacement for my FH engine thinking it was a 40mm stroke as advertised. He lists a 115 rod length in the add. Cant be with a 40mm stroke unless he has the jug to match. I suspect he is using the 38mm/110 rod/low pin type piston, but have no hands on to know. This engine I have in pieces must be a GT5 as the head studs are fine thread. If the piston on the long rod tops flush with the cylinder, then there is a GT5 jug. Its the only way it can work. The half breed engine in the 40mm jug and comes up 2mm short. Both SHOULD come up way short in the GT5 jug.

This is confusing!
