I am glad to have found this forum. It has been helpful already and I have hardly ridden my 2002 Yamaha Bear Tracker YFM250 ATV. I just traded for it in a swap for a couple of older snowmobiles. It wasn't running. It's cold here in Maine and I don't have a heated place to work. It didn't have spark so I spent a lot of time tracing wires and replacing most suspicious components. Finally success. Now it won't stay running, I am about to get reading all the helpful advice from the posts to see what the problem might be. Happy to be part of your community. Thanks
