I remember trying to stay up with (in a car) two guys riding two-up on a Sprint in '64 or so on back roads, so they aren't to be sneered at.
Good eye. That heat shield might well be the most valuable part on the entire bike, from a collectors or restorers (if any such exists for these things) POV. It's in surprisingly good condition, and I've never seen another one that wasn't mostly wasted. I'll see if I can track down some pics and post up something about the Bonneville racing stuff if you're really interested. I should make that a new thread though, since stretched out Bonneville LSR bikes are almost completely the opposite to desert sleds, even if they both run across deserts.Nothing says "raw power" and "narrow-focus track day tool" like a gray fiberglass heat shield.
Also, Mr. Bang, yes, matter of fact I want very much to know all you're willing to say about the engine's innards. Please. And about your LSR bike, if you have the patience. What class/es? What speeds? Thank you.
I talked to my buddy who owned the bike, he put it up years ago on VFT and actually connected with 2 people who knew that company, and in their brief existence it was considered a better frame than a C & J or Trackmaster, Redline or Champion at least in their opinion. As well another guy responded who worked there and believe he built it originally and gave Hal the name of the racer who rode it, but he wasn't a big name. Hal is looking for his notes.I was gonna say that's a Champion frame, but mostly by default (couldn't think of any other likely builders). The Cycle Factory sure has a familiar vibe to it but details are unavailable to my decomposing brain. That bike certainly does have a lot of the good stuff, yup. It's yours now, I guess? -- You did good.
Throw your photos up on vft.org (For Sale VFT). I know that's the site's For Sale page, but people post questions there about bikes' histories, specs, etc., all the time. There's a lot of deeply knowledgeable hillbillies in the vft clique who'll be happy to share what they know, remember, guess, or invent.
I believe they are Betor, or possibly "Metal profile" but will chk my parts piles as I took in some Betors off Bultacos and wheels ( alloy) for a upcoming BSA tracker project (64 spitfire hornet, too boogered up to restore so street tracker it is).Heh heh, nice. I wonder who made the blue bike's triple clamps. ... And are those Norton forks?
