Hello gentlemen,
My recently acquired 4k mile '09 exhibits what I perceive to be CARB/DOT compliance tuning symptoms - more specifically a somewhat annoying fall-on-its-face between gear changes issue making seamless shifts frustratingly elusive. Depending on the degree of throttle opening, rev range and load where gear changes are made seems to be a factor. It just feels as if a slight fattening of the fuel map in conjunction with perhaps an ignition timing revision would cure the boggle. In steady state cruise conditions and roll-ons, regardless of gear position or road speed its faultless, no lean surge or hick-ups of any kind.
I'd like to keep it absolutely as OEM as possible, I.E. no piggy back devices. Even the exhaust system is perfect for my tastes as the quiet nature of the bike is a major plus so any modifications there wont happen.
Have any of you successfully remedied this boggle - perhaps a simple ECU re-flash would do? I thank you all in advance for any pertinent input.
regards,
