Today should have been my dream day. Me and my dad went bike shopping and came home with a 2001 CR125. It's awesome and I couldn't wait to ride it so I got it home and hopped on. Everything was great and like I expected, at first, then I was on a straight and all of a sudden she just died, just like that. I couldn't keep it running after that. It just would not stay started. I don't know what I did. So I took it home and first tried the plug. For one it's not the plug listed in the manual and for two, the gap was way off. So I had another plug of the same mode, an NGK, and I reset the gap on it and put it in but it didn't fire up right after that either. So maybe the plug isn't hot enough. Could that be it? The bike is bone stock and looks like it's never been ridden. The dealership said it was bought there and only gone for a week. What in the world do you think could have happened, and has it ever happened to anyone else?
