Jetting.. once again.. Only a little problem. Installed JD kit, zip ty screw, hotcams in/ex, and a FMFq slipon. Everything works great.. Going with 170mj, blue needle 4th clip. The rest is stock. But when i am riding at normal speeds on the road, say 40-50mph, the enginge miss a little.. Almost as a plug/spark problem.. Every 10-15`th second it get 1 little miss.. a little more throttle, and nothing`s wrong.. Great response as well.. Is it the needle that needs to be down/up 1 clip, or do i need to change pilot jets or something else?
