So I am helping my friend with his bike. It's a 93 zx6. It feels like the bike hits a wall around 5 or 6k. Not sure what rpms because there is no tachometer. Also this bike does not have a stock exhaust. It's a Honda can. My geuss is that the honda can allows more air flow and tr carbs stock jets cannot not supply enough fuel. Will a jet kit solve this? Which kit should I get. There's a dynojet kit for a hundred or am I better off buying bigger main jets.
