Old multi-cylinder bikes of the 50s to later on. Japanese, British, Euro, etc

While we are talking about emissions, the RD400 Daytona was a special American version, they got it instead of The LC.
they knew the emissions were worst on a closed throttle so they simply put butterfly valves in the headers , close throttle , shut pipes, passed emissions testing
Then the poor bastards got RZ350's with cat converters.

Um, dunno, can't see tank badge to see if its supposed to be an impostor. Kawasaki bought out Mellurgo (or someone like that) who made a fairly convincing A7 copy (I'm not that clued up on old BSA designs, maybe a A10), whatever. But about a Decade ago they released a retro version what did they call them? W6 or something (too lazy to google).

pretty close they did a 500 and 650 had a shorter stroke than the A10 and some had twin carbs, i think some even had a 5 speed likely an alloy cylinder as well. The lateast Kawa (muzzaB has one) is a totally different design with a bevel OHC (completed without googler)
thre was a Twin carb head on Ebay for about 40 US a while back i couldn't get Kicka to buy it for his a10.

i think there is a 2 sec gap between them on a big track .. i have rode both . the later bike over turns where the later one one will run wide but in saying that i think now i know more you could jak the ass of the nf4 and steer it better .. dennis Charlett did try to make a old model go as good as the later ones but even he could not pull it of .. good guy to talk to about it

It's a bitsa A W1 with a A65 tank

**husaberg** · 3rd February 2014, 16:14

I would have said an A10 tank around 59 with the chrome panels painted as the center bolt looks high and the tank looks long, but not so sure now.
either way looks better for it the Kawa never looked right..... just needs a better shaped seat now. plus the round badged tank i guess.
IMO the bsa's actually look better with the Suzuki GSX tank anyway.......Grump will have a pic of Howard's or Jungles. While i am f-ing off the purists.
Throw in A mo Harley frame with a couple of inches taken out as the A65 steered better for the missing 2 inches anyway......(Fing ugly engine though)

On the whole all Bike engines are all dirty.......If don't believe me compare the fuel efficiency and and emissions for a modern 100hp bike and 100hp car.......

yeah was kinda what I was meaning, the dirty Guzzi and Buell in the garage even tho FI would put out as much shit in the air as a well tuned stroker on quality fuels, as for a diesel engine... come on way dirtyer than a stroker I have the same as you YL on start up they stink like hell.

What frame? To put this tandem twin into. Or make one? Triangulated chrome molly tube perhaps?
Twin shock or single? I'm assuming bare bones look.

put the tandem twin in side by side, with a bmw or guzzi transmission inplace of your PSR , carbs forward like a reverse tzr , pipes could be vaugley reminisint of cx500, would be a cool bears bike

Of course I realise that with the big twin (say 1000cc there would be much bigger cylinders/crankases and pipes to deal with, but with simultaneous firing, could it be possible to use only one chamber, would two be necessary?
