I have a 2001 Banshee all stock. I am going to put FMF SST and a Pro-Flow adapter plate with a K&N air filter(air box lid removed)on my shee this weekend. My question is what main, pilot jet should I run in it? I do most of my riding in the sand dunes(Gordens Well).

 

I'd start with three sizes fatter on your mains. If testing indicates too rich, then drop down one size. At sea level, I'd bet that three would be about right. Get the mains jetted before doing any further changes. If a problem occurs in the 1/4 to 3/4 part of the band you could then raise the needles to the 4th position from the 3rd. Since the pilot circuit only controls from idle to 1/4 throttle, I wouldn't think you'd have a problem in the dunes with the stock pilots.

 

My friend has FMF fattys And he had to go all the way to 300 mains.
