I know it's still early days with you and this forum, Andrew !

I wish someone would taalk and show pictures about their motorbike..

Here you go Paul, a picture of my Harley Davidson Superlow 1200T;



Unfortunately at the moment I am unable to enjoy a ride out on my Harley as the bike is in temporary storage in a safe and secure lockup due to us replacing our old dilapidated 30+ year old garage. This was leaking water whenever it rained and had a asbestos roof. It was permanently damp and cold in the winter months and had to go. We now have a new garage and I have just painted the concrete floor with a specialist garage floor paint that takes 7 to 10 days to fully cure. So I am unable to garage my bike in there until the end of the week when I can recover the bike from storage and hopefully (weather permitting) get out for a few rides before winter sets in.

Nice

One for Baggo.

A short YouTube clip of a Nimbus being started and revved up. Sounds nice.

[Baggy Trousers]

Thanks Philip.

At the end of this clip is a YouTube thingy for a Nimbus sand racer. The interviewee here is my chum Bo Nielsen (who owns the green bike in your clip) and this gives an excellent oversight of the aspects of the Nimbus which make it such an interesting machine. Bo is keen on sand racing and is a regular competitor in the UK and at the famous Rømø meetings in Denmark.

Frankly, I have never seen the attraction of hotting up the Nimbus engine. It's notional output of 22hp from 750cc is hardly dramatic but adequate and the torque is more than enough; the 3-speed non constant-mesh box is slower than a Burman on a cold day. If I wish to relive my adolescence, I can wheel out the XBR500. Besides, the 2-bearing crankshaft is hardly ideal for souping things up but I have to admit that it fares better than the 1.125" Austin Seven crank which was subjected to numerous power increases in the 'twenties and whipped like a paper clip. Incidentally, apart from the crank, the Nimbus shares another feature with the A7 (not the BSA!) and that is gallery jets aimed at drillings in the crankshaft which admit oil to the big ends as a centrifugal reaction. The OHC driven via the vertical dynamo at the front comes from the Wolseley-engined Morris Minor of 1928. Nimbus adopted the idea in 1934. But Peder Fisker (the Nimbus creator) was not a copier - he had trailing link front suspension and a swinging arm in production in 1919 - and had many other patents in advance of industry orthodoxy.

Did I mention that I'm rather enamored of this very individual and thoroughly engaging motorcycle?

I rode the Puch Maxi to a classic vehicle gathering yesterday...


It was a superb turn-out with some awesome vehicles there.

But this really stood out




A 49cc Fantic moped chopper. I'd never seen one in the flesh before but do remember seeing them in pictures many years ago.

49 eh! I 'member the Honda 50. Killer!

[Mike H]

Fab Dave!

I've a honda c114, ir was the early uk motorcycle version of the Honda 50 step through..unfortunately still in bits and only part restored

[andrew Ivimey]

Better get on with it then, Steve ! -sounds great.

[jack]

I had a Honda 50. Still have nightmares about it...

[andrew Ivimey]

I didn't and I don't. Buy I had a chum who had a utilitarian attitude that was hard to fault - he git to be where he and others wanted him to be!

Sammy Miller motorcycle museum autumn workshop update.

I think Baggo will revel in the content. I found it very interesting.

[Mike H]

It was interesting. He's still going!

The disc valve reminded me, some years ago I read or saw something about torpedos, not sure who's and I think it was sometime during WW2, anyway the propeller was driven by a little IC engine with a conical 'disc' valve, the cone shape made a cone shaped combustion chamber space in the head. Longevity, or working life, wasn't an issue, as it only had to keep working for the couple of thousand yards or whatever it was to reach the target.
