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.
In other words, do put enough miles into the two years.
Warranty issues in my case were: solenoid, sprag clutch, rear wheel bearing (2), rear sprocket, low fuel sensor (2), RHS mirror and a few cosmetics. All within 7200 miles.
Others: chain replaced at 7000 miles, 2 of the small bulbs, 1 bolt heat shield.
After a run through the forest the coupler of the small light in the casquette used to disconnect, not any more.
Currently at 11000 miles, two months from expiration warranty.
Original twin spark still going strong, as does the battery. No complaints there.
Whether in front of the convenience store or at a park people step up to make a talk. Oh, can you rely on that! Do like it. Often yields good stories and inside tips of whatever subject. You meet interesting people standing by an Enfield.
It took me well over a year to adjust. From a matter of fact approach I've moved to a more 'empathical' relationship, if that makes sense to anyone. It's different, but feels proper.
