still more jetting problems

2 posts in this topic

I turned out my pilot screw 2 3/4 turns and changed my main jet to a 160 as the FMF site says when running their exhaust. I thought this would take care of my idling problem. Anyone else running FMF exhaust? What sort of settings are you using? Thanx!

The jetting specs FMF supplied were ballpark figures. If you provide an in depth description of your woes, you would get much more help and discussion about your problem. You make no mention about whether you have turned your black idle adjustment knob. For some reason, many 400/426 owners won't use that knob/adjuster at all.
