The hesitation on my bike was there when I bought it new from the dealer, so the SAS/Canisterectomy didn't have anything to do with it.
I did make it a bit better by installing the crossover hose between the rear cylinder/left side plug and the front cylinder/right side plug that I said to remove and replace with bolts.
That being said, the only way I found to get rid of the hesitation completely was to use TuneECU.

Yep. I put on a set of Wings and didn't need it so I figured I'd get rid of everything while I was at it. I put the Wings on it because the stock exhaust got so hot I honestly could forsee someone being burned on it very badly. You could feel it radiating off the exhaust cans.
