I also made the transition from sport quad ('00 banshee) to a 4x4 'ute('03 rincon) and it is a hard one to make, indeed. To add to this, the rincon is alot more stable in off camber situations than the grizz, (but the grizz's ground clearence is the culprit, and well worth it) so I can imagine it was tough for you. I like to play on boulders, logs, ditches, etc. all the low speed (crawling) stuff that makes it want to tip. I did soften my suspension and set the mud lites to about 2.5 psi and this helps alot, man the grizzly will will go over anything! The way I ride and obsticles I like to tackle are the reasons that made me switch to the grizz from the 'con in the first place. The front diff lock, low range, and almost 2 more inches of ground clearence really make a difference. I sold my 'con to a buddy whom I always ride with, so I really get to analyze the two machines head to head. I am constantly waiting for him when he gets hung up on a diagonally fallen tree branch in a creek when the only front tire spinning is the one in the air! He has titan 589's so it holds it's own in the mud until my ruts get too deep.
On thing you will learn, and probably already know from riding a sport quad is that body language makes all the difference. When traversing a side hill, if you can approach it with the right side of the bike on the high side, it's cake, you can stand with both feet on the right side floorboard and literally dangle your body weight off the right side of the bike, hanging with your right hand on the grip, operating the throttle/ front brake, and your left hand hanging on to the rear rack. Of course I recommend this only at very low speed, and not on a hill that is simply unreasonable to traverse. Hills on the opposite side (left side high) are more tricky, 'cause you have to reach all the way across the bike to operate the throttle, but, you can still make quite a difference by standing with both feet on the high side. Try this once, it works for me and I'm 6 foot 200 lbs. you should be able to make the bike want to roll UP the hill! lol. My solid rear axle buddies (kodiak, arctic cat, polaris scrambler) laugh at me 'cause I need to do this, but, I get the last laugh when I need to pull them off of logs, rocks, and out of the mud! Be careful and have fun! Later, Clint.
