NEVER SATISFIED Posted March 11, 2005 Report Posted March 11, 2005 I'D SAY START OUT AT 300 MAIN.. 27.5 PILOT.. AIRSCREW 1.5 OUT FROM SEAT NEEDLE AT 4TH CLIP... THEN WARM IT UP ... TAKE A FEW RUNS... PULL THE CHOKE OUT HALF WAY AND IF IT RIDES WORSE THEN YOUR RICH AND YOU CAN BEGIN TO LEAN IT OUT.... IF IT RIDES BETTER THEN YOU NEED TO RICHEN UP ... YOU CAN DO THAT TO DETERMINE THE NEEDLE ...THE PILOT... THE MAIN... 0 to about 1/8 throttle is controlled by the Pilot jet size, and fine tuned by the airscrews 1/4 to 3/4 throttle is controlled by the needle taper & length, fine tuned by the clip position 3/4 to WOT is controlled by the main jet size DSICLAIMER: TAKEN FROM JETFACT Quote
ellison445 Posted March 11, 2005 Report Posted March 11, 2005 I am running Toomey T-5s with no air box, Toomey 2into 1 filter, Vforce reeds and I have in a 280 mian stock pilot and almost the same elevation and it is perfect!!! Good Luck, and do a plug check! Quote
richybanshee Posted March 11, 2005 Report Posted March 11, 2005 (edited) Remember: Wave propagation, and air flow, between different pipes is ....different. So jetting for FMF pipes will not be equal to jetting for, let's say, T5's. I had FMF pipes so: Depending on temps, main jets should be around 270 -300. Needle may need to be adjusted depending on the main jet size. pilot jet should be around 25-30. Try the 280 main, needle in the 3rd clip position and 30 pilot jets. Down size on the mains if needed. If you take off the airbox lid completely I suggest 300 mains. Edited March 11, 2005 by richybanshee Quote
