My 64 LR all original except for a repaint 25-30 years ago and the wrong front fender.(I Think) 3000 Mi on the odometer and I believe its true because I've had both engine side covers off and it looks new inside and doesn't burn any oil. Not as nice as yours but a good rider.
Wow! That's a very nice 64! Looks like a west coast model from the rear fender. East coast models had the valenced rear fender. Your front mudguard does appear to be a replacement, but a wonderful bike!
Have you ever had the VMCC run your s/ns through the factory data base? It is a worthwhile thing to do. If you need details, let me know.
