From: R P on 14 Sep 2009 13:45 Is the 990 going to remain the spec for next year? Is there still a twin cylinder limit & a multi-cylinder limit?....or is it 990 across the board? Are there any more endurance races [motorcycle] I mean that are left. Like LeMans,.Bold'Or,.Spa & such? Ya never hear about them any more. Never hear about side-car racing either? I've heard it still goes on in Canada,..but on a very limited schedule. Ron

From: R P on 14 Sep 2009 15:27 man has it been three years,..I thought this was the [change-over] year,..??....then I heard talk that they weren't going to? What ever happened to the K/Roberts / Petronas engine?....V-5 I think. It's a shame we lost someone like John Britten....& I don't mean that in a selfish way either. But he was genius! Ron

Unlimited tuning is an expense problem; if it is truly unlimited, then you're talking about prototypes. Gotta have limitations, I think, and for national-level racing, rather low ones. 675cc triples, sure, and also 750cc twins. > But in the long term that may > not have been in the best interests of the sport. Not following you there.
