Off idle stumble when in stop & go traffic
« on: August 15, 2009, 08:23:32 PM »

I had the SERT & dyno work done, has anyone experianced this stumble when bike is hot in stop & go traffic, 1500 miles since work, need to have some info before taking back to dealer, hopefully just an adjustment. you really need to slip the clutch to keep it from doing it. removed cat & Reinhart slip ons.

I experienced the same thing. Took it back to my tuner and he "fixed" it. Todd G. @ Century H. D., Medina, OH.

Sounds like you have a hole in one or both VE tables.
Hole being a low (lean) VE cell or two at low TPS and low RPM (off idle).
Use graph mode to help spot the hole.

Too lean or too rich will cause a stumble.
