I recently got my ECU flashed and now the throttle response is VERY jerky. Jerky to the point it's dangerous to try and feather the throttle while in a turn because you can't turn the throttle without it feeling like it's going to buck you off the bike. It's worse in the lower gears at around 6-8000 RPM's. Here's the kicker, it only happens about 3/4 of the time. Sometimes the throttle response if perfect. Any Ideas what could be doing this? And just to give you a heads up, I've been riding street bikes for 30+ years. I'm not Marques but I definitely know how to ride.
