hmm ok, interesting discussion but a little OT
as of late i've been building most of my bikes on the conservative end of the spectrum, i've got a polini'd za with a leovince that barely goes 52, i've got a TSM with a SHA and a 70 airsal and a stock exhaust, the ciao is fun and quirky and i love it but with 20 mph gears and a malossi 43/proma setup its turning 10k rpm at 45 mph and just not any fun to ride, it shakes out your fillings and breaks your earholes.
i want to build bikes that i like riding, that are reliable, and reflect the character of the original bike. I got a couple blasters in the works but for the most part i'm digging on simpler stockish builds that will stay running for more than one season.
