6 grand? With a stock Zuki and no PT&T...or did you bore the carbs? Those numbers are similar to the modded Zuki's w/ PT&T from this area. I bet you could sell some of your tuning secrets, like getting around the rev limiter, to some of the guys around here. I was told it kicks in around 5800 or 5900; but I don't know that for a fact. I guess you are expecting 38-40 mph with the PT&T? I'll let you know how much hind tit mine will suck in a couple of weeks.
