I just purchased a new grizzly and so far am impressed with the power and size (sometimes need to ride two up for hunting). I have read about the High Lifter clutch kit and K&N filter for my GRIZ, and wanted more info about what improvements I might expect if I purchase them. I am not a "racer" but have noticed the "ABRUPT" clutch engagement, and wished it would hook up a little smoother.

 

 

Put it this way. With these two mods you will get better airflow to your airbox, more throttle response, a slightly faster top end, cooler engine, lower rpms, and a bigger smile that you decided to buy the mods.
