I've got a '83 KZ750 L3 that I'm boring to 810cc; I do mostly high RPM highway riding and I've got a Bassani 4-1 pipe. The bike wasn't jetted to the pipe and has always run lean. I'm looking at a Stage III Dynojet kit and ditching the airbox for K&N pods to remedy the situation (I realize it'll take some tinkering to get it tuned) but can't figure out if I should buy the 82-85 KZ750 Stage 1 / 3 Kit or the 82-85 GPZ750 Kit (Stage 1 and 3 come separate). I've got the Mikuni BS34 4-bank stock carb on it currently. Can anyone point me towards the right kit to buy?
