Okay, I have a bit of a problem. I have my carb jetted at 240. With the air box lid on it takes a second to accelerate, but with the air box lid off it has a lot more take off power. So I jetted it down to a 230 with the air box lid on. It still does not accelerate as fast. I don't mind leaving the air box lid off if I am riding around by house. But if I go on atv rallies I don't know if I am getting into deep water or mud, so I don't want to leave my lid off in that situation. Please if anyone can give me any advice it would be greatly apreciated.

 

from idle to takeoff is the pilot jet. not the main jet. try changing that.

 

i hope someone answers ya bud cuz i just put a 38 mm airstryker on mine and i had take my lid off and leave it off lol and still not getting enuff bout try a k&n but i go into deep mud too so im weery also

 

I threw my stock air box away the first day i bought my lt250( shoulda sold it on ebay). I also have a 38mm air stryker arent they great! i just have a outerwear which will bead away water, and dirt usually hits it and falls off. The carb side of the outerwear is kinda loose so i just use electrical tape and seal the K&N nice and tight. Youll need your airbox only if you plan to submerse the entire bike into water as outerwears werent designed to get soaked. I find this works really well just replace the tape and clean the filter/outerwear after each ride. The stock airbox helps hold the carb in place so id suggest buying some heavy duty hose clamps to keep your carb on tight.

 

thanks man will do and already have heavy clamps seeings it was a bi!@# to get the carb in boot even by heating it off to buy filter what size main jet u running and what kind pipe wanna see if im close lol
