290 Main FMF Fatty 30 degree's

[DirtDiggler]

I have a 290 Main in it now , pretty big think I need to re-jet ? LMK

sounds pretty good if there is no lid on the airbox, if thats what u were running in the summer, i would step it up to a 290

im at 290 with no box at all so im thinking it will be ok , im probably 1 jet higher than what i should be for my elevation

i would do a plug chop just to make sure...

I was running a 290 with f7 air box and vf3's and it was just a bit rich
