That's funny. You've obviously never seen me ride. The #1 was a Maty Smith tribute, it now carries #522 also for Marty Smith's first title year. The '77 cylinder and GEM reed that was on it I'm now running on another Elsinore with a DG pipe, picured and you're right about how it runs. Your bike now has a '74 cylinder I boost ported to the specs GEM used to send with their kits and it has a yamaha RD350 reed block welded on. I cut the original mid-silencer canister off the Protopipe that was on it and routed the stinger inside the frame to get away from the pass through hole in the number plate, the silencer now exits through a hole in the inner fender like the Mugen pipes do.
Man the memories are coming back to me.
YEAH that WAS a 75 cylinder on it because the first engine I built for my friend he grenaded at the air strip he rode at in Sandusky, put the rod right out the bottom and wasted the cylinder. AHRMA put the nix on any elsinore cylinder that didn't have an opening through under the exhaust port. The 75 up castings in that area were solid because of the bigger exhaust port.
I had to whip up another engine for him to race at round 1 in Florida where he got 2nd.
I have my boost ported cylinder somewhere.
Should have seen the bike when I had a shinobi water cooled head on it.....fastest snore in the country at the time.
As for where that pit picture was shot, I havn't a clue, its been a long time and several concussions later, my mind isnt there anymore.
