ive been pulled over at 52 on a garelli noi polini, 6p, ported, case matched, gearing ???, 21 phbg blah blah blah...
stock ported, 17mm, high gearing had my minarelli v1 sebring @ 40-42 depending.
the polini had it running 50 at 3/4 throttle ... couldn't get it tuned to not four stroke and die at full throttle without being way too lean everywhere else :/
the new polini (after a selling the old one a while back) has its hitting 45 at half 3/4 throttle all day... still breaking in and have to re tune afterwards.. super rich :/
not that confident in my gps tho... but im passing cars one 45mph streets :/
