    not really, take it up to 70 and it's a good size for running high end power

    still no mail from tweak

    using a kwak z650 with z9 (900) carbs as a guide, oversize carbs are a liability if you take them too far. the bike in mention does about 20 to the gallon, smokes like it's a 2 stroke and won't rev. all because the carbs are too big. this is a bit extreme but re-jetting a 21mm carb to a 50cc barrel willmake the mix in wrong. can't think how to explain really.
