tootall, I have been a honda fan all my life (that is all I owned other than one kawasaki but it was a gift and a POS). As for honda here is what I have owned:TRX90, TRX300, TRX450, TRX500 "Rubicon", TRX 650 "Rincon", XR250 Dirtbike, and the kawasaki bayau 220.
My opinions so far on the grizzly (100 miles on the grizzly) are that it has more power on demand, better suspension of ANY honda for rock crawling (and is ajustable), and bottoms out much less. It also has as good if not better engine breaking as the rubicon along with a locker on the front for those sticky situations and even an override button when locked in low 4x4 with the diff lock enganged you can over-ride the rev limiter. My wife says that it is much easier to steer than the other honda's. If you want something that will perform really well in the rough stuff I would suggest either the Rubicon or the Grizzly. The Grizzly has the better options/ride though...
As for the gas boiling that issue was fixed with the "finned" plastics to let air out. I have run mine in 90degree weather all day in low range and stopping to cut trees alot and it NEVER overheated. The fan stayed on alot and it was warm on my legs but the light never came on and the radiator never boiled and the fuel was fine...I belive yamaha has fixed this issue
