I've been using those as an option for a couple years on 1100's. Guys that like to idle around in the trees like them as the 4s has enough torque to get it done at low rpm. Some say it makes it seem a little more laggy, which it could feel that way because it is a lower engagement spring, and that makes it a greater rpm range before you hit boost at around 6k.
