I have a 2004 Foreman 450S looking for a close starting point on the jetting. Upgrades Include: .020 high comp wiseco piston, stock cyl. head, hmf Utility slip on, k&n air filter and 2" SNORKLE. (performance package from atv outfitters). I installed the 138 main for starters. Wot seems to be close. Extremly lean in the mid range, clip in bottom groove, even added washer under needle to richen a touch and still lean. Touch the choke and it takes off.
Back in my racing days we use to change the needle with more taper to richen the mid range. I'm not sure where to get a different needle for this carb.
any Ideas?
Thanks
