What size main jet will a #50 needle jet fit in? I live in Florida and the quad is popping like hell at about 6000 rpms. I talked to the dealer about ordering the main jets and he suggested to just put the needle jet at the last slot. i still think that I will need to re-jet the main. Does anyone live at sea level and can you tell me what your running? I'd rather not spend $30 on trial and error to achieve my goal. Right now I have a white bros slip on and a k&n inside the box. The box is not modded in any way. I ride through a lot of water. Any suggestion would be greatly appreciated!! Thanks in advance.

 

Come on!! Somebody has to know something.
