I got my 95 CR500 CA Plated. It was a lot of work and money.
I started off with an E-Line External Stator (200w) Call Baja Designs, they were making a copy that was as nice if not nicer, and it allows you to actually run lights. Stay away from the 35w add on stator. Thats only 35w at MAX RPM. . . on a 500? - otherwise it wont light up your front fender. . . even with the proper bulb.
I then bought their XR400 D/S kit with their LED Tail light. It has a battery in it. (they have a new kit that is all self contained)
I then registered it in AZ. Then you have to wait a year, and transfer it to CA as a "trail bike". The odometer had to have over 7200 miles on it . . . (use the Vapor model)
If I were to do it again, I'd use Baja Designs new LED headlight. It takes a lot less power to run and is B R I G H T !
I have pictures if you want. EM me and I will send you them. BTW - If you go to Ebay and check Completed Items? you can see it - the guy I sold it to just sold it for a little over $4000. . . (he super moto'd it. . . I sold it to him as it came, just with lights)
LATE!
