I did them on my buddy's '02 CR 125 last summer. It wasn't too difficult. If you are thinking about doing it yourself I would recommend picking up a Clymer Manual for your bike first. The instructions in them are pretty good, follow them step by step and you'll be back on track in no time. If your not up to the task yourself I would avoid Honda Extreme. Although I have never had anything fixed there, their prices always seem way to high. Let me know how ya make out.
