Jetting Question.....

[WingerDingerEX]

did a search on jetting for a HMF slip on and got some info.
Mods:
HMF slip on
K&N Filter
Airbox Lid off

They said to run a 150-152 main jet
Pilot jet?
Needle position?
:confused:
Thanks in Advance!

I'm no jetting whiz but with what you have I would try this;
1. #155 mj
2. #40 pj
3. Needle clip in the 4th slot (counting from the top).
4. Air/fuel (pilot) screw 2 turns out from the seat.
This set-up seems to be where mine runs best at (except I have a #158 mj).
I just recently tried putting my clip back in the stock position (#3) and 2 1/2 turns out on the pilot screw and it feels really doggy especially on low end (up to a quarter throttle). I'm definately putting it back the way I had it.....................:cool:

I would say to try that except maybe a 42 pilot to aid with cold starting.
