I would go back to the Foreman 500 with foot shift. They are more dependable, with less to mess up, especially in the cold temps. I am a Honda man, but I agree with quadracer, the Grizzly is a nice ATV. I like the diff lock that Honda doesn't offer and it is true they will really pull hard. They also have a great ride. I don't know about reliability with the Grizzly, though. I'm not saying that they're not reliable. I'm just saying I don't know if they're AS reliable as a Honda.
Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!
You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.
