JUST INSTALLED A WHITE BROTHERS E-SERIES PRO MEG EHAUST. STARTED THE QUAD UP AND LET IT IDLE AND THE HEAD PIPES TURNED CHERRY RED IN COLOR. WHEN YOU RIDE THE PIPES COOL DOWN. SHOULD I ADJUST THE CLIP ON THE NEEDLE AND GET A BIGGER PILOT JET OR WHAT IS THE PROBLEM?

 

go a size bigger on the main jet.... and maybe one notch down on the needle....yea down I think to gives it more gas....you're just runnin too lean

 

THANKS I'LL TRY THAT TOMMORROW. TRX440EX

 

Changing the main jet and needle position will not cure your lean idle. Put in a 42 pilot jet and you should be alright.

 

yea thats true...

 

I HAVE A 300 EX WITH A FMF PIPE I ALSO HAVE IT RE-JETTED BUT THE PIPE STILL GETS HOT, I AM NOT SURE ON THE PIPE YOU HAVE BUT MINE DOES NOT HAVE A HEAT GUARD LIKE TH STOCK PIPE MY RIGHT LEG WOULD HEAT UP AND MELT MY PANTS ON THE PIPE, IT ALSO MELTED MY DAUGHTERS PANTS WHEN I TOOK HER FOR A RIDE BE CAREFUL, I JUST BOUGHT AND AFTERMARKET EXHAUST HEAT SHIELD IT WORKS GREAT (THE COMPANY I BOUGHT IT FROM IS JAMES LUCKY 1-800-233-2637 IT WAS $26 TOTAL GOOD AND SAFE INVESTMENT GOOD LUCK WHATCH THAT PIPE EVEN IF YOU RE-JET IT WILL STILL GET HOT WITH NO HEAT GUARD
