Maby...

 

I've had the same issue with my f4i, where the battery connection got loose, and my bike was stuttering when giving it constant throttle. Nothing as extreme as yours, but definitely noticeable. Not sure if that will completely solve your problems, but hopefully it will address some of them. Good luck.

 

the only reason i am convinced is because it did the hesitation over bumps, other then that i guess time will tell...another question, where your positive and negative connections are, is there a nut underneath of the little tab that you have your grounds to? or is a welded nut underneath? i just dont know how to secure these things down so this wont happen

 

Your talking about the battery connection... yeah, there should be a square nut there. I think you can get them at any parts store.

 

Sounds like you're running lean. JMHO

 

I love it when i, or anyone else believe they have a serious problem and discover the dreaded loose connection. The wave of relief is refreshing.
