was riding today and after a couple of hours I suddenly lost a noticeable amount of power and the bike would sort of sputter (the power would come on and off in quick succession). I looked at my header pipe once I got back to the truck and noticed the retaining socket cap bolt had fallen out. Do you think this would decrease the seal enough to lose compression and create the problem I'm describing. I should mention that I wasn't using a header gasket (dumb ass) -- but I've never had the problem before. Other possibilities I could think of would be the decompression lever (the one mounted to the engine) got stuck open somehow? Or maybe I've got a dirty carb (although my dad and I cleaned it not too long ago). Your thoughts and suggestions are appreciated!
