I'm a fairly new rider and want my f3 to run well again. My problems started when I had the notorious charging problems with her, I replaced the rectifier and new plugs as they were burnt out, it kept draining the battery, I then replaced the stator and it's plugs were burnt plastic as well. Fixed that and started charging and running again. I had to pop the tank off and in doing so I misplaced a plastic connection from the vacuum line to the adjacent hose, i replaced it with a simple connector. Anyways when I rev in neutral it redlines great 1st and 2nd are good too . 3rd and 4th seem to lose power completely at 9 10g Rpms, 5th and 6th do the same but at even lower rpms around 7-8g. I'm wondering if it's maybe the spark plugs, air box or a fuel starvation error? I just wanna go fast again.
