His motor does not have a longer connecting rod.

The 40 mm stroke is 2 mm more than a 38 mm stroke motor because the lower connecting rod pin is drilled 1mm closer to the outside.

His motor needs a PK style piston with the lower wrist pin hole.

A Skyhawk / GT 5 piston has the higher hole.

Who knows what a Flying Horse motor really is as some vendors call any and all of their motors by that brand name.
This might help ya
