just put my pipe on thursday and used 147.5 for main jet and 50 for pilot jet and it runs like a dream.

 

try a 150 main jet and see what that does..and then buy a k&n and see how you run.

 

is that what you run?

also do you use your airbox lid?

 

I'm running a Prodesign Foam Filter and 150 main....runs perfect...plug is tan..its excellant....but in this cold weather i put the 145 in and it runs perfect...I have the pro design intake so the filter isnt held on by the lid but Yes, I am still using the lid.

 

WHAT SIZE IS THE STOCK JETTING ?

 

145 main jet..dunno about the pilot
