790 engine,air box removed, thruxton needles, no shims, 45 pilots, 150 mains , EMGO streight thru mufflers and Pro-Com Ignighter @8500 r.p.m.

I have been concerned about the air fuel ratio ever since removing the air box, and now its finally dialed in. Was fairly close, the only thing we did was remove shims from neeedles.

Very happy with final results, as you can see 61.5 h.p. at the rear wheel at 7,500 r.p.m. and air fuel ratio of 13.2 with a streight line across the r.p.m. range.
