I heard that the 2013 model fixed a TB issue that the 2010-2012 model's have causing one to want an Injectioneering fix.


Does anyone here have knowledge of this?


BTW what a fun bike!

Good question. You could see if the years take the same throttle body part # or call injectonengineering

I have heard opinions that the '13 was considerably smoother off idle than the '10, but I don't know for sure.  Less smooth than a well tuned carb, but it's something that you can get used to.  There are regulars here who own them both ways, wait to see what they say.

I have a '13 and it is fine for me in stock form. I can't compare it to a '10-'12 however.

What mods have you done to it? What kind of riding are you doing?
Thx, Russ.
