Yes it's true.

Removing the system completely is a little more involved but just stopping it from functioning is easy. Down by your shifter there will be a short section of rubber hose in each of the lines. Remove the hose and replace with 4 high temp silicon vacuum caps. Problem solved and easily reversed if it should ever be necessary.

Are your pipes and jets still stock? If both are and your getting backfire, then you may have a bigger issue then the AIS.

Nope sorry my mistake. I think I spend too much time on message boards that I don't even "see" the signatures anymore. But yes an AIS removal took care of most of my back firing issues. That with a PMS adjustment, got rid of it completely.

Over the years, I've always felt that the stock pilots in the 650 were a bit too small. If I ever do another one, instead of messing with the AIS, I'll probably just change pilots and re-adjust the PMS.
