ok, I had an exhaust leak around the header gasket, but the cruiser was running good....now I got new headers, new gasket, no more exhaust leaks, but the cruiser is sputtering when I give it some gas at high rpm's. I just got a new roll cage built and the fuel tank got drained and taken out...so I thought it might have been the fuel filter, but replaced it and still the same problem.....could my carb be out of adjustment now that there are no more exhaust leaks? any ideas? it was running really good and that's the only thing that changed! thanks
