Turn a 2HP into a 3HP?

[The Muffinator]

Other than changing the crankshaft, what else would you have to change to make a 2HP a 3HP?

 

[Richard Trotter]

The rod and the head.

The rod and the head.

Oh right, forgot about the rod. The head is different too?

I think the head has a little more volume. Keeping the 2hp head would give you higher compression. I know this is true for the 7hp and 8hp briggs. The heads are interchangeable but the volume is different.

I already have a Predator 212cc motor on another bike. This frame is too small for that size engine.
