03 accel pump stalling

OK, I've got my o3 450f working very well. BUT, this weekend going up a very slippery hard pack road the back spun and stepped out big time. I reacted by backing off the throttle and then rolling it back on. poof, fire went out. I figure it is the accel pump flooding it out. Anyway to slow it down from squirting at low rpms?

The AP doesn't react to RPMs. It reacts to how quickly you open the throttle. It can be tuned and generally needs to be on most of these bikes. Unfortunately no one fix for all. So you need to do a little diagnostic work and then some trial and error. See the following links for more info.
