Warrrior jetting

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?

FMF says with just an exhaust, 150 main. If KN filter and open airbox, 155/165. Try it out and check the plug.

As for the float bowl screws...for the first time, just take the carb off the vehicle, and get a good phillips screwdriver. Hit it with a hammer as you twist.


Got sand?

Re: Warrrior jetting

thanks cleartoy and WW, I got the carb off and with a little tapping, i got the float bowl off. Replaced the stock jet with a 152.5. Seems to have even more bottom end and I havnt got to get out and let it breath yet (kids are napping, big gun much loader). I discovered why I might be getting a false plug reading, the little clear rubber doohickie on the bottom of the airbox was full of filter oil. May have gotten a little too much filter oil on the filter. Thanks again for all your help, I cant beleive how much more power those changes gave me.
