Dave Coupe and his Elsinore are just about unstoppable in the +40 Expert class. Dave's engine is built by Sam Alexander and just flat hauls the bacon. (For a good picture of Dave airing it out check out RacerX online
http://www.racerxill.com/020604_AHRMA_BobbyM_1.cfm). Jim Dallas also rides a Sam Alexander Elsinore and last year dominated the 250 novice class. He got bumped up this year so we'll see how he does.
I've built a pretty good engine and suspension for my bike and I got the NW 50+ intermediate title. I really want to ride a bike with one of Sams engines to compare. Sam and I have gone round and round over piston port vs reed valve for several years now. All in good spirits mind you.
