AndyH Posted February 4, 2014 Posted February 4, 2014 (edited) Jones 1942 supercharged two stroke (!!) flat four. The Norton colours are misleading but maybe a Norton frame?

Found this link: http://www.eriksbikeworld.com/index.php/bikes/vintage-racers/25-supercharged-period-4-cylinder-racer Blimey! He's a fair chap. That is special . Wonder what power it made? Funny how many innovative designs there were around over the years here in UK, but nothing really stuck in mainstream British manufacture & factory racing - whilst others (Italian/German etc) were doing all sorts of stuff. I mean we were racing singles still against the Gilera multis etc & stuff that was innovative never really got a good run - say the Roarer or whatever - but then I suppose the same could be said of Guzzi with the V8, so maybe it's not just us. Longterm, maybe mainstream is the only viable product, & innovation just dripfeeds into that. Sometimes it gets me pissed when you see every week in MCN the latest "special" from some boutique custom shop, which is a few is chopped parts & a paintjob.
dangerous Posted February 5, 2014 Posted February 5, 2014 having had turboed bikes and being a stroker fan... I fail to see how forced induction can work on a T2. A 2 strokes fuel mix cirulates the crank bottom end if that was under pressure shit could go bad, also the way a chamber works needs to happen naturally, ie: fumes exit the port with the shock wave the next batch of fuel follows the shock/sound waves bounce of the revers cones and pushs the fuel back in to burn the fumes excaping.

I think the blower replaces the crankcase induction of your normal two stroke. Exactly how, would take a better engineer than I could ever be to explain.
luhbo Posted February 5, 2014 Posted February 5, 2014 Search for split-piston, u-cylinder and other terms you'll find in these findings. As you said, a standard stroker can not make any reasonable use of a blower. But looking at the pictures of the crankshaft of this particular bike I guess without a blower it wouldn't have made one single burp at all. It would be interesting to read something about how he managed to start it. Nice peace of craftmanship, nonetheless. Hubert
dangerous Posted February 10, 2014 Posted February 10, 2014 ok, so just back in from a bike rally way down south... found this, what is it?
Admin Jaap Posted February 10, 2014 Posted February 10, 2014 That's a Guzzi Falcone (ex army) from the 60's/early 70's
Baldini Posted February 10, 2014 Posted February 10, 2014 It's a Nuevo Falcone. 500 single. Made 69 -76. Quite a few about here, mostly recent imports I guess.
dangerous Posted February 22, 2014 Posted February 22, 2014 and this . . . ? MG LeMans 1380cc 140hp... well thats what they reckon, dont think its real yet. I like it but the skinny arse end that is typical these days be good to bring the LM name back but would be a bugger in one was as mine wouldent be the very very last LM any more.
AndyH Posted February 23, 2014 Posted February 23, 2014 I saw the stuff on this and I was intrigued. I particularly liked the rear shock position concept but in practice it would get filthy right next to the rear wheel.
AndyH Posted February 24, 2014 Posted February 24, 2014 A bike spotted at a local pub hangout last summer. MV 750s America, but whose signature is that on the tail piece?
