>>I just tested compression on the bike (just bought a guage) and it read 85psi (6 kg/cm2) is that normal for an A3? cant find compression specs listed anywhere in the shop manual.<<
Yeah, 85psi is about right, I dunno the exact specs either, save that it's like 9:1 (whatever that means).
>>some1 also posted here about cutting the air box and adding a larger main jet for more power, does this really provide that much of an increase? (is it worthwhile?)
since i have a Dellorto on my A3 and parts are easy 2 get im up2 doin it.<<
I wouldn't bother, it's way too much hassle for what little bit you'd get out of it.
You could get the same result but pulling the stock exhaust baffle.
