Howdy Bman. I have ridden in the a lot around NY waving at cops thinking I was legal. They never bothered me. There are a bunch of NY MBers here and I hope they join in. If your a going wild and force their hand, I think they would make an issue. But tooling around, stopping at stop signs and not jumping curbs, don't think it would be a problem. I would have my license with me at all times though.
NY is the only State I know of where they have that catch 22 has to be registered but you can't register it. Drives ya crazy, eh? But typical of cops in the North East, you don't annoy them, they won't go out of their way to bother you. I mean that as a compliment to our law enforcement. Found a thread on some NY grass roots stuff. http://motorbicycling.com/f17/new-york-laws-1474.html
Hope it helps.
