Okay, I've put a Big Gun head pipe and silencer on my new Warrior, I've also put a Pro Design Pro Flow adapter and silencer and drilled a few holes in my airbox. Everthing I've read on this board and other information advises to re-jet to my condition. I've checked the sprakplug a few times after I've ran full throttle through a few gears, half throttle, and just putting around. It pretty well looks good( not white indicating lean). It does develop a miss in high rpm's, possibly starving the engine, when it didnt before. This tells me the main jet needs to go up at least one size even though spark plug color does not indicate this. Any advice. I attempted to take the bottom of the float bowl off the other day and they must have had tools from another planet to put those phillips head screws in there cause I cant get them out. 'Spose they loctited 'em from the factory. If so what to do to get them out. I understand loctite is pretty much mandatory on a single cylinder four stroke. Is there a product out there that cuts loctite so you can remove small screws without stripping them?
