i would guess that the 280 would most likely be about right, see what others have to say before you try it, but I run 300's in my banshee with the mods in my sig. Its safer to be rich than lean. Did you adjust your pilot jets at all?

[SpeedDogz]

no olny air 2.5 out

[SpeedDogz]

with 280 jet and 2.5 turns out for air it is a dyno jet stage3 kit

[SpeedDogz]

and the needles on #3 so it set up 280 jet air is 2.5 turns out and new needles on #3 sound good or bad www.dynojet.com say to setup like that but just did not no what jet to use pl help kit only come with 3 jets 2 needles and 2 clips for a low prices of $95.95 mmmmmmm hehehe but it is fun

somewhere around this forum, there's a chart for jetting. if you are running the lid on your airbox, most likely the 270 will be too rich. it seems like i was running a 250 main jet with my lid on, and it was just right with t5's.
stock, i believe is a 200 main
pipes, you bump 5 sizes on the mains
removing the air box, bump 5
putting vents and removing the snorkel is somewhere between 0 and 5

maybe someone can link you the table with this info in it

that sounds pretty decent to me, its a lot of trial and error to figure it out. Didn't fmf give you some jets with the pipes or suggest something for the jetting

[SpeedDogz]

no
fmf only give me pipes card kit from dynojet
