    2011 hesitates at clutch engagement and under throttle

    I bought a 2011 with 1900 miles at the end of last season. It was in mint shape but obviously hadn't been ridden much. Everything is perfect about it other than a hesitation when giving it wide open throttle. It is not accelerating as quickly as it should and if I back off a little it seems to then lurch a little like it wants to come out of it. Also a little stuttery right at take off / clutch engagement. Initially thought injectors from sitting around not being ridden, I've run seafoam and injector cleaner through it with no improvement. I bought it of the second owner, I thought maybe the original owner had an aftermarket exhaust and put the original back on prior to selling it without changing the map, but I checked and it's the stock map. Changed the plugs, when I took the airbox off I found it had not been seated correctly, half of one of the boots had been folded up. I thought that would be the problem as it could throw off the air mixture possibly. However no change.
    Any thoughts Definitely seems like a fuel/air issue.

    Did you do the 12 minute tune? That would be my next step.

    Crash is right. If it's been running with an intake leak for a long time, it may have adapted to it to a degree. The 12 minute tune will reset any adaptions. From cold, start the bike without touching the throttle, let it idle until the fan comes on then let it run for another 12 minutes, still without touching the throttle.

    Ok, update, just got back to working on it. I re uploaded the stock tune, reset adaptations and have tried the 12 minute tune. It won't make it through the 12 minutes �� stalls out periodically, which I'm assuming isn't ok, then stalls out and won't start without giving it throttle right about at the temp the fan will be kicking on. At this point in the retune I think the computer is so mucked up it barely runs at all. Sputters and dies, backfires, etc. Getting frustrated, any words of wisdom??

    Try waving an unlit propane torch around the air box connections and the vacuum lines. If it's a vacuum leak and it starts pulling in propane the engine should rev up.
