Yes It's pretty much a MUST to remove the AI. It is a small vacume operated pump uner the tank the runs to those tibes next to the spark plugs. It causes your header pipes to blue quickly and badly. It takes air from the air box and injects it into the engine. There is a vacume line at the left carb (if memory serves if not then it's the right one) that has to be removed and capped there is a hose to the air box also needs to be removed and blocked and the 2 lines next to the sparkplugs need to be threaded out and plugged. then under the gas tank the little vacume pump comes off with 2 bolts. It's an easy job.

I learned all I need to know about life by killing smart people and eating their brains.
