58 HP is pretty damn serious already.  I don't imagine anyone is really feeling the driving need to improve on that too much compared to the 50-52 they're used to.  The engine is so strong it could be a fairly competitive flat track engine in stock condition.

I would like to get rid of some of the engine breaking, not sure cams or a slipper clutch. Or both , I run 100 obtain fuel so might put a hi compression piston in
