both the 350 and 500 have the dished plates. memory tells me that the dishes face inward to the center of the clutch.
That's what everything I've read said, also, which is why I was surprised when I took apart my clutch for the first time. I promptly brought the whole thing, hub and all, to the dealer. (Not to the parts shop who sold me the clutch which I gave to the "mechanic" which may or may not be the one which is actually in the bike, since I didn't watch him take it out of the box and install it, mind you...)
The dealer's parts shop assured me it was correct and that this was a new style not yet in the parts books. I saw another clutch come out of the box this way at this parts shop, just like mine and the OP's.
It's India...this could be one of many things and I may never know. So many people regard mechanics as a matter of voodoo, and reaching accord in a conversation is far more important than getting what might be known elsewhere as "facts" or "truth." But I don't put it past RE to change a design, either.
Edit: Kevin or any CMW people reading this, care to comment? Underhill, did you contact them and what'd they say?? Maybe they'd know about a quiet design change the rest of us have not been privvy to.
