My bike had been running lean and missing/popping above 5k, so I adjusted the needles to the 4th clip setting, which helped some, then to the 5th. The bike doesn't miss or pop much now over 5k, but you can feel it losing power. I put new jets in it earlier in the year and just found the kit I used. The main jets are #102.5, so I'm planning on rejetting soon. Where should I start if the only mod to the bike is a 4 into 1 header? I have VM26s with the accelerator pump. Sorry to keep posting about this issue, but I know now that I need to rejt, just unsure where to start.
