I am considering buying this kit for my GRIZZLY I was wondering if anyone has purchased one and how much of a differance it made if any.!!!

 

i bought one, it cost about 130 but to rejet it and install the kit , it cost more than i thought it would, it says it gives 10% more power or something, i cant really notice much, but i put mine on right away and didnt have the feel of the machine, i might put a pipe on and hope that the combination of the two helps more than either by themselves

 

I purchased one and installed it myself. Pretty easy installation. I gained no top speed, but I believe that I gained a little low and mid range torque--but rather hard to tell. I am also planning on putting on a new pipe, and will try the new jetting with that also.
