All very true, and if I had a 350 in the US I'd certainly want to try to get it bored out to a 500/535 if possible...110kph running flat-out just isn't the kind of performance it's probably worth the trouble for. But no one in the States seems to know much about the 350 UCE, as it's never been available Stateside, so I might have kind of an orphan bike, too.
It's just that I'm getting the bike set up exactly the way I like it now, and I would be sad to leave it behind. Then again, maybe I can bring the specific parts I like back with me (bars, mirrors, fenders, exhaust, whatever) and build something similar on a US enfield, too.
It'd just be cool to have one from India with my story behind it, though. Guess that's why I remain dedicated to the idea, however impractical. And I was figuring customs on an over-25-year old frame is pretty much the easiest way you could deal with importing any motor vehicle, as it's exempt from federal requirements.
I also dunno if I'm headed to the US at the end of 3 years. Might be able to get another African or Asian assignment that suits us...
