I have just cleaned the carburetor and powervalves and I am trying to dial in my new bike. Does anybody know what type of jetting would work if I have an fmf fatty and a shorty silencer. I will be riding around 3000-4000 ft. The current settings are SJ #52 1 3/4 turns out, main jet #168, and needle in position 3.

Well, that sounds like it should be close but each individual bike may be different.You should do a wfo plug chop to determine the main & go from there. I have the same bike & my jetting is the same except the main, mine is 170 & a little rich. I will try a 168.

You can go to the fmf website under Tech Center and they will list the jetting specs for your bike.
Main: 170
Pilot: 58
Needle: stock
Air Screw: 1.5 turns out

Good Luck!
