i wanted to see if anyone can help me out with what main jet to use. i have heard 3 different opinion a 150, 155, or 160. my set up is pro circuit head pipe and silencer, aftermarket air filter, end of snorkal removed. i am leaving the lid on the airbox because of the conditions i ride in, but have considered drill a hole like i have seen others do.

 

altitude?

i'm pretty close to sea level running a full CT system, K&N, snorkel removed, 3 2" holes cut in top of lid and run a 160 main.

 

I am at 1200' and running an HMF slip on with snorkle baffle removed and a 2x2 hole in the airbox lid. I am using a 165 main..

 

Hey what filter you got!! The brown truck is bringing me a noss billet adpt and a uni for 60 bucks from e bay. Ive been running my stock one with the lid off.Your main jet is close to mine any probs or air screw adjusts.

 

Call PC and ask them what *they* recomend for there pipe!!! I run with a K&N and adaptor w/outer wears...and the air box lid off...160 main jet...stock needle lifted 2mm...and the air flow screw out one turn...with the stock pipe. Killer mid range punch!!

 

I have the Noss adapter with the Uni filter and it is a sweet setup..I am running the stock needle and stock setting on the air screw setting. The machine runs like a raped ape!

 

i got the job done today i used fmf/dynojet kit 155 jet, needle set on third knotch, and air/fuel mixture 3.5 turns out. procircuit said use it that way or leave stock setting and 160 jet.

 

rec6397,
Is that the third notch from the top? That is what I put mine on yesterday. I just got the FMF power bomb header and the power core 4 pipe, K& N filter. That is the notch the guy from Alba suggested I start it on! I also have a 155 main.
