Hi all. My wife just bought me a 2003 plated WR450 for Christmas. The battery is shot and won't hold a charge but it starts right up with a couple of kicks. Went for a couple hour ride Christmas day and my only complaint was a bad mid range flat spot. After searching this forum, it sounds like it is more than likely a partially clogged jet. I also noticed on this forum that the 03 has starter problems, so before putting in a new battery and pushing the button I wanted to fix the problem. Before buying parts I would like too know if this has already been done, the guy I got it from has no idea. How can I tell if this has already been done?
