I just bought a set of FMF SST pipes and PowerCore II silencers. I'm running a K&N air filter with the airbox lid on, but snorkel removed. I typically use a 32:1 premix, ride from 0-1000 feet above sea level, at an outside temp of 70 degrees. I have found some various suggestions for jetting, but I just wanted to see if anybody out there has the same or a similar setup, and what settings you've been successful with. FMF's website suggests the following settings (but they don't get into detail about what pipes or silencers they are using)

 

Main Jet - 260, Pilot Jet - 30, Stock Needle at 3rd position, and 1.5 turns out on the air screw.

 

I've also heard people say 280 main jet and 27.5 pilot jet for this. Anybody have any first hand experience with these pipes that could give me a good starting point, or does this look like a good place to start? I want to have the pipes on for memorial weekend, but don't want to get lost in the jetting and not be able to ride! I'd rather deal with the stock pipes for another weekend than be lost on the jetting and not be able to ride at all! Thanks for the input!!!!!!!!! :blink:

I'd say start at least with a 280, maybe a 290 or 300 and a 30 pilot. Start out with the needle in the 3rd, but once you take it for a spin, try it in the 4th and see if it's better.
