Does anyone have any suggestions on what to check for me. Here is the deal 04 Preddy 90 with the usual go fast goodies. It is having an occasional sputtering issue, Seems like the first moto it runs great second moto when it first takes off it sputters and acts like the choke is on, then it usuall clears out pretty quick, then just seems like at random times it will sputter again on and off. Compression is good, carb seems tuned good since it's just happening on and off. fuel flow seems to be okay, and doen't matter if the plug is new or old. Is there some problem with the electrical on these I don't know about that might cause this?
