Atvs are real popular here in Southern Arizona. I have had a couple of friends with big bears, and they have been bulletproof. I have had a yamaha bear tracker in the past, and currently have a grizzly 660, and a Banshee. We only buy Yamaha ATVs,as their drivetrains are the best in the industry. Its hard to find a good deal on any used Yamaha utility quads here, the rental /trail riding businesses buy them up. Sport quads are plentiful, and cheap though. Like someone mentioned on adding a fuel filter, great idea, especially if filled from gas cans. I think you will really like the Big Bear!
