Wondering if you guys could help me out im bought a pipe for my 05 raptor 660 and after the first ride the pipe is turning Cherry red during high RPM so i was suggested to JET it out but have no idea what Jet to use...

Any information is greatly appreciated.

Thanks
Russ

 

Forgot to say that this is the only MOD i have done so far to the Quad.

 

If it's a full pipe and no mods to your air box then I would try 150/155 mains

 

150/155 sounds good to me also, I wouldn't ride it anymore till you get it rejeted though.

 

Thanks for the reply's i went to Recreational Leasure but they sold me the wrong kind of jet or something the one i took out was round they gave me a Hex head one. o well have to go back on monday.
