Visited the show today, and spent most of my time nosing around the Royal Enfield booth. Lots of 500cc single Bullets on display, and several of the new 650cc twins, that are supposed to be available in the spring.
I thought the twins were quite nice. They are elementary bikes. Priced right. If ever a potential market was going to break loose with some $$ for a new entry level bike, this might be it.
Looks like basic valve adjustment will be simple. There are four bolts that hold down the rocker cover. The cutaway engine showed that valve actuation is via forked rocker arms and lock nut and screw.
The throttle body assembly appeared to me one cast piece containing both TBs.
Here's a few pics from the show.
