In post #46 davidd showed John Surtees with a Norvin. I have a couple of questions. First, the Vincent name on the timing chest is in script. Any thoughts on this? Second, can this photo be definitively placed as 1954 or 5? This is in aid of dating the early existence of the Lyta type short-circuit tank.

Regarding the Norvin for sale in Austria - in my experience high level pipes can get mighty warm.

The timing chest logo looks like the Firefly tank transfer.I recall seeing a photo of Ted Davis with a similar one on the front of his helmet.

I sent a BMW logbook to the DVLA , together with another change on another bike , they made the change on the other bike in about 6 weeks but NOTHING for the BMW. I contacted them and they said they never received it. Although I pointed out the BMW book was sent in the same envelope as the matter they had dealt with they continued to assert they had never received the BMW logbook, and I should send them £20 for them to issue a new BMW logbook. I told them I would see them in hell before I paid for something they had lost, and that I would contact my MP the press and anyone else I could think of. There was quite a lot more agro for a while, and then as I was cycling through Reading on holiday (Don't ask why we were holidaying in Reading!) my mobile rang, and when I answered it a girl enquired what colour I would like on my replacement logbook (No apology no admission they had the logbook all along etc) I told them the THREE colours of the bike only to be told they will only put TWO colours on the log. I said put whatever you like, and they sent me my ORIGINAL log book back a few weeks later.
Like my local council, the HM Revenue and Customs, and one or two other organisations, who have A LEGAL RIGHT to extract money from you, and who HAVE NO COMPETITION. they can, be, and are totally inefficient. but what the heck it keeps someone in employment:(,
Colin, u r not alone: During corona times, u hv to ask for a visiting date IN THE INTERNET over here in Germany. I called instead, got a date on the phone 3 weeks later and was there in time. But, their monitor did not show my date, so I adressed someone, working there and was adviced: " Go in without, they do not
bite." So I did. The office with 6 employees in front of their monitors, no other customer in there, me adressing the first to the right. Had all my papers, being customer there since 40years, by now, the
person behind the screen refused to deal with me, because I had no date! I had nothing written, no proof
of my phone call - went home, lost battle, new attack in the net, new date, new try 2 weeks later, same
scenario, success!
Don´t worry, after u hv made them function, u don´t see them again!
Don´t argue with idiots!

Looks like I never uploaded a picture of mine, still the same but going to fit a Vincent straight absorption silencer this spring in an attempt to make it a little quieter, the "Goldie" on it is a bit too anti-social.

Chris, this one looks like a nice bike to ride! Contrary to many others, who still use the standard kickstart,
which they fit at half-way of its travel, to maintain knee-grip to the tank, or maintain full travel and loose
knee-grip. Moreover, you have a touring handlebar fitted, which delivers a much better wheight distribution and rider´s comfort compared to clip-ons. The oil tank looks a bit small to me, although I know, that I experienced repeatedly on mine a very low oil-level in the tank after some riding without
checking, but never had problems by low contents. On mine, I am using BMW K100- footrests, which very
effectively keep vibrations off yr feet. A much better rear brake is a Grimeca 200mm dia (also 220mm avlbl.), as used on several Italian bikes, like DUCATI GT750 bevel. It is still availbl. new and lighter than the
Norton one plus including a rubber shock absorber, so softening drive forces until yr primary chain.
From the compression of yr front forks I guess, that you are still using the standard springs, which are
too soft for the bike´s weight. (a Manx weighs 60kgs less!). If you are riding, the chrome rings will dissapear completely in the upper cover tubes, so leaving only a very small rest of fork travel.
This, plus the steepening of fork angle by compression delivers an impression of front-heavyness, which
feels lorry-like, especially when braking into a bend. You will be much more happy by using the distance
tubing on top of each spring on one side only and add a new one on the other side. Much better comfort
and quicker reaction to direction changes.
No doubt a real improvement to the standard Vincent motorcycle, if nicely assembled!

Michael I’ve been unable to find one of these hubs, I have one fitted to my Egli which I borrowed from a Laverda - I’d like to buy a new one if you can tell me where to look please?
I’ve fitted a modified Honda 750 kickstart to the Egli using Ernst’s splined shaft which you told me about and it works well.

Little Honda, it has a Norton box so doesn't need a long kickstart, with the touring bars (Suzuki Bandit) and a big belly I'm positioned well back so there's less weight on the front, I'm using progressive springs and 20w/50w oil in the forks, they work really well. The oil tank is bigger than it looks from this side, it's well forward behind the carb and I've never had it get too hot., The primary's an open belt with Commando clutch and a crank mounted Lucas 3 phase alternator.Chris Launders bikes 077.jpg

It has changed in minor ways since this was taken, guard on the top run of the belt, Mikuni's, passenger footrest and plate gone and another rear chainguard.

Looks good and good-working. When I see the open primary, I am immediatly remembered on my teenage years long ago, riding a fan-cooled 50cc Kreidler moped to a disco, some 15mls away. ´T was
cold, and I had dressed to impress the ladies, not to say, didn´t have money for motorcyclist´s leathers.
At the disco, my right foot felt like a piece of ice, as the fan of the cylinder cooling had eaten the shoe
lace of my new and polished low shoe, so effectivly blocking my dancing abilities!
Back to subject: No main stand: Do you always start her with yr left foot on the ground? At 70+ (some
of us r) this will become a problem.
Enjoy!

For hubs/brakes speak to Howard at Disco volante moto.
good advice, Normski. On the spot, I found fllg. at ebay: 273779221975, 283431152229, 132409164769,
273996490453.
these r most scnd hand parts. Look for FALCONE, which is cheaper. Sometimes, there are new compl. units.
Otherwise u hv to collect. Also try other Falcone parts seller´s adresses by asking them via ebay.

Yes I do start it astride but I'm well behind you, I'm only 67, the motor only has 7:1s in it and combined with the MK2 cams and the Norton box and primary gearing turns over easily, slowly but easily that is, it usually takes 3 or 4 kicks to start, I think that's more to do with getting enough fuel in with the Mikuni's as it has coil ignition. You will notice there's a toe guard on the brake lever and the Commando clutch doesn't have any protruding sharp bits, also I wear safety boots for riding.

No, I tend not to ride it off road, and with being on the left anything thrown up by traffic is on the other side.
I've had a Triumph for 30 years with an open belt drive that's probably 1/2 as high off the ground and that's not had anything in it either in tens of thousands of miles, the only times I've actually known someone have that problem was with rear belts, notably Harleys where of course your own wheel is chucking debris about along side the belt.

On my Egli Comet the belt is tucked away behind a modified standard cover. Front air scoop with gauze exit at rear of clutch
(good example of reusing scrap the ESA had eaten away the dome on this cover I found on the scrap heap)

For starting I am going to try what T.T. says, Prime the cylinders before starting,
Turn it over a few times on the vale lifter,
I have been doing it with the Comet, No Valve lifter, So Put it in gear and Push and pull back a few times,
With the Comet it makes first kick instead of 3 ish from cold with Amal Mk2, ie No Tickler !.
The Comet has an old Mag', I worry it might fire and take OFF :D .

The Comet is not really a problem, But the Old L/ning is getting too much for me.
