Hello. I'm new to this forum. I just bought this big bear. This thing is show room condition. Now I haven't had time to dig into it so it might be easy to fix. But the guy I bought it from said it needs a CDI box. Now is there away to test these to see if it's bad? I see they are hard to find. Any recommendations on batteries? Any help would be greatly appreciated. I'll get back with results one I get time to look at it.
