fmf sst jetting

[03banshee04]

I just installed a set of fmf sst with titanium silencers, also have fmf reeds on stock cage and clamp ons with +4 timing adv,put in a 30 pilot,4 th clip on needle with 310 mains,havent run it yet. was just wondering if this sounds too rich,at about 400 feet above sea level,also running a champion 8332 plug,with amsoil 50-1,just want to now if this is a good staring point? thanks

I have SSTs with K&N no lid and stock reeds. I have stock pilot, needle in 2nd pos and 310 mains and the thing is perfect. I started with 3rd clip on the needles and it was sputtering so I put it in the 2nd and it cleared right up.

That sounds good to me ... try it and let us know what you found out. I recommend you do the plug chop method. If you do not know how to do the plug chop method, well, go to

I think that if you are 400 feet over sea level without airbox lid you are very close to the correct jetting. Keep in mind that every machine is different and you may need to got up or down a few sizes.

310 mains for 30-50 degree weather, needle 4th clip from the blunt end, stock pilots have always been the best combo on fmf pipes that I've found. Your very close, and I'd run it to try it out, then try the stock pilots and determine which ones work best for you.....This jetting is also for k&n filters w/ modded air box covers or no cover at all..

the richer pilots will richen the needles as well. If you try stock pilots, then richen the needles as well to compensate.
