I recently ran into a problem with my '09. I installed a Woolich log box on the bike and started using autotune and everything was running fine. Then the bike sat for a week and I took it out for a ride and now when I'm in first gear and I go wide open throttle from like a 40/50 roll the bike will cut throttle at about 10k RPM and jerk violently, if I roll into the throttle it's fine, I just can't be wide open until after 10k RPM. I thought maybe it was running lean but I've changed the tune many times and nothing makes it go away, my chain was kinda rough so I change it for a new one, and I thought maybe the kickstand switch was acting up so I deleted it and it's still doing it. Just looking for some ideas or suggestions.
