changing front forks on a cr500

You can go online or to your local dealer and order a maintanence/repair book for your bike. It will tell you step by step how to replace the fork seals and clutch plates/springs. The fork seals will run you approx. 15-30 bucks and fiber clutch plates will cost in the 7-50 bucks depending on quality. The book will cost 20-35 dollars. Clutches are very simple and easy to work on but i would get someone else to do the fork seals/I have never done that before.
