I'm trying to get a feel for where I should be on my jetting. I have FMF pipes and a Pro-Flo filter with the airbox lid removed. I currently have 30 pilots, stock needles-clip in stock position, 300 mains. Let me know what you are running.

 

I'M RUNNING .280'S WITH K&N/PRO-FLOW,STOCK PILOTS, NEEDLE IN CENTER/ STOCK POSITION, WITH TOOMIES, GOLDEN SPECTRO @40:1 ONE BOTTLE FOR FOUR GALLONS OF PREMIUM, BEEN RUNNING GREAT SENCE NOV.88, VERY FEW FOULED PLUGS.

 

Im running Fmfs and I have 35 pilots and 340 mains...I also am running the duel K&N s at sea level...with a bunch of compression..Hope somehow this helps..

Sik you are running the correct jetting for sea level with FMF fatty pipes and powercore II silencers with a K&N filter with proflo filter adapter and the airbox lid removed. Alba Banshee's come with the exact same set up as what we are both running... I know because I live 3 mins from them and I got all my stuff there including my Banshee.

 

Im just recently put in Pro Circuit pipes, Pro Filter w/K& N filter, Boyseen reeds, reed spacers, boost bottle & no air box lid.. I'm running @ sea level also with stock needles and positioning. I also posted in here for advise on jetting. The advise I got was to run 300 mains & 30 pilots jets.

So far I have only made (1) trip (Pismo Beach) on this setup and it seems to be okay (hauled serious a$$). I'm not sure if the jetting is 100% dialed in as yet, but it is real close. I did call Alba's service dept to pick their brain and was told that they run the same main size, but slighly larger pilot jets (32.5). They also run their own design needles in the 4th clip. So the setup were running is real close. Anybody try running larger main jets like 310's or 320's with basicly the same setup? If so how did it run??
