I purchased my 2009 Grizzly in 2-09 and have over 900 miles on it to date. No problem with boiling gas or stalling from day #1. Most of my riding is in the desert or mountains and the AZ temp is rarely below 40 so I have no idea what it might do in cold weather.

I bought mine with ITP SS212 wheels and 27" ITP TerrraCross tires, and had full skid plates installed as part of the purchase deal. Installed a Yamaha rear rack extension from Canada, CB radio and antenna, 1/2" peg risers, horn and lighted license plate frame and mirror (to be street legal), Warn back-up light, Thumb Assist PRO, and a heavy duty rear mount for a d-ring clevis.

There is no lack of power and it will go wherever I have the guts to go!
