It's really not much hassle. And precisely because the bike is so gutless that you have to look for ways to make it better. And I think 33HP was measured at the ad brochure, not at the rear wheel
No one says you have to do anything. I'm just trying to share what little I know.
In the old days, when someone would come to the shop and complain that their bike wasn't fast enough, I'd put them on the back seat, take it out and redline it in all gears. Then I'd ask "At what point was the bike to slow?"
Usually the person was scared half to death by that point and never mentioned how slow the bike was ever again.
With these bikes, it's a different story. They are legitimately slow.
All the bikes with the over-stretched cam chains are running cam timing so retarded the valves should be traveling in a little yellow school bus.
Nice to be figuring out how to make the bikes a bit snappier. Preferably without major work and bucks.
