If problems are going to occur they are mostly likely in the beginning and well within the warranty period. It is really rare to have any kind of fuel injection or engine problem.
BTW there's a gorgeous '52 Enfield in a shop window on Market St. in SF. Fully restored with (they claim) 3500 original miles on it. $7500 (cough cough) though the website says '55/$8000. I guess it got cheaper and younger at the same time. If only I could do the same!http://shopmulholland.com/the-roadtrip/motors/royal-enfield
Thanks to all. I just spoke to my local LE dealer, and set up my purchase for this summer.
