I agree...at sea level your main jets would typically be in the 270-300 range with the mods you listed. Your setup sounds very similar to my old setup and I was running 280 mains, 27.5 pilot, needle in the 4th clip from the blunt end. :cheers:

dont fell bad its not that simple you just have to try to get a feel for your bike i would start around 310 and work my way down that is what i did you may not need a pilot you may be able to adjust air screw good luck

my old setup was t5, v force reeds, no lid box at 900 ft

 

stock pilots 1.25 turns out, 4th clip of the toomey needle, 340 mains

 

 

if your at sea level you should be 350 or more i would guess.

 

 

also the guy with 220 your so lean it horrible

 

stock mains were 200 and you have mods so you need to go up to 300 easy i would say

220 sounds about right. I have v-force 3's, FMF SST pipes. k&n airfilter, prodesign head and boost bottle. I called two local yamaha dealers that both told me for those mods the pilot at 25 is fine. I coule switch the main to 210, 220 max. I ride sea level. 0' to 100'. So I hope this helps. I also asked if I should put the pilots at 27.5 and my main at 290. they laughted and told me I could it I don't want my bike to last. It is too flat for people who ride at sea level.

You have no idea what your talking about. On fmf's website they tell you to jet to a 260 main WITH JUST PIPES at sealevel. Im runing: fmf sst's and a k&n filter with the airbox lid off @ 1000 ft. above sealevel. Ive got in a 320 main and 30 pilot. My Banshee came from the factory with 220 mains :yank:
