A short update on my Enfield:
I was growing really tired of the headlight bulb burning out pretty much every time I rode the bike, so I changed it for a high power led headlight (6$ from china, including housing. Good enough light (more powerful, but narrower beam) It has not failed in many, many miles).
I also had to repair and re-enforce the aluminum fenders. That's pretty much it, only other thing I did is some minor regular service.
It's getting some very, very heavy use. I take it to the single tracks in the woods a couple of times per week. It even gets some air time there....
