I recently switched from a completely built 2whl Honda CR250 to an 02-660 Raptor. I added a Race series super trap pipe, Pro taper Bars and clamp, and some other crap, but no motor work. What Id like to do is add a stage 1 cam but am not sure what else I will need to do. Id like to keep the stock boor. Cash is not a big problem, Im more concerned about somthing that is going to run well, and have a little more midrange. Do I need new valves? Springs? etc. Id appriciate any suggestions.
