Thru my 16 years and 150,000+ miles of riding I have had the privilege to own 6 street motorcycles of my own (along with countless other dirt bikes, ATVs, snowmobiles, etc....) and though I wouldn't consider myself a Kenny Roberts, I would say I am above average on riding skills. Of my previous bikes, none have had this kind of "jerk" or snap when coming off of a closed throttle position.
My reasoning for asking the question is to verify that the machine itself is functioning correctly, so I was looking for some technical information on how everything could be verified prior to considering something is actually "wrong".
I'll be quite honest in the fact that I don't ride around looking at the tach, so I am guessing the RPM level is around 2000rpm. When I ride, my eyes are forward looking at the end of the corners and not 3 feet in front of the bike, but given the poor overall condition of the roads here in Minnesota, you have to make changes and correct mid turn. I haven't had the privilege to memorize every corner within 100 miles of where I live, so sometimes the commitment made to the corner has to be changed, because more often then not there is a pot hole, crack, or length of highway crack-patch that I'd rather not risk crashing over, so correction is required.
I am actually suspect that the ECU is unable to hole the flies at a low throttle position, thus leaving a "gap" in which one can actually modulate the throttle in a position in which the flies are non-functional. Several of the threads I have read about people removing the flies / Guhl flash have actually said this phenomenon goes away. Thus leading me to believe that there might be something to the theory. It is also why a different cam profile on the throttle tube could improve it or correct it.
