Thought I might as well post my dyno results. This was a tuning exercise so the graph shows before and after. And the numbers are AT THE WHEEL.





Keith,

Could you post your set up? Displacement, needles, shims, mains, pilots, etc etc. Thanks for posting your run.

I'm really beginning to wonder about my seat of the pants jet sizing ability. Full throttle runs, backing off on throttle to notice if bike accels or decels, checking plug colour, comparing to others who have posted is all myself and many others have to go on (no dyno).

I'm guessing I'm too rich. Why do the Bonny riders with 360 engines all seem to run 110 pilots, smaller mains, and more aggressivly tapered needles (Thruxton) but have higher stock HP.....Cams????
