I would accept the consensus here on the H120 engine's BHP but hope it's from a dynamo as the info on the net ranges upward to 110 or 120 but it's not clear whether that's at the flywheel, rear wheel, or just what.
I don't see how the improved flow and raised compression could have produced less than a 10 - 15 percent gain over stock BHP - but I'm a rookie at this
