How much mileage is recorded on it now?
If it is over 20,000 miles, and as old as it is, it may need to be rebuilt anyway.

Have you run it with a stub cable and power drill to see if it works and does not have
the speedo needle 'twitch' we in the USA refer to as "Smiths palsy?"

Either way, a speedometer rebuilder can set the odometer to any figure you request.
If you are rebuilding the engine anyway, you might as well have the speedo rebuilt as well,
and begin both at "ZERO."

Charlie Barnes has mentioned to me that he had to bore the case and press in a steel sleeve to fix cases on his race engine.
Another possibility instead of electroplating is to use electroless nickle. No problem with hydrogen embrittlement.

Keeping in mind that the '67 emblem is plastic, and thus a lot lighter in weight than is the die-cast '68 - 70 emblem, you might get away with it.

The only question I have would be if the two emblems are the same size to look correct in the pocket of the tank where they are meant to be fitted.

Also: know that the '67 emblems had specially molded rubber pads under them to prevent cracking.

...the instructions say "with a rocking movement" to pass the recess in the tube when refitting but the rings are hard so do not do that movement like the O rings could do.
I am applying these movements are force but still nothing.
Evident that with dozen of times trying the edge of the rings will be dulled and possibly let me fit it but may be damaged...

Thanks for all your help guys......

I managed to free it up using WD40.....took it apart and cleaned it all.
Once I'd done this I understood (together with the above comments) how it works.

I assume this is not a standard Triumph part....or is it?
Never heard of one that can be adjusted like this before.

Hello, not an idea but in my 48 500 all four valves and seats are bigger than the stock small ones possibly due to easy to find car ones some decades ago.

BSA OIF Head Steady


That IS one that I saw... Actually THE one that I saw. I was going to let it sit a little while longer before making an offer. Folks seem more keen on offers if it's been up longer than 2 or 3 weeks and since I'm not yet really near the point where I need the head steady I guess I can wait it out a little! Thanks!

Is this question about this video? It is an introduction to my YouTube project, trying to break a UK land speed record with my Velocette.


I don't know! You wrote it in the last sentence in your blog. I'll watch the video as soon as I've posted this reply...

EDIT: Yes, I think that must have been what you meant. Looks a great project. Are you allowed a nose fairing? If so, and with clip-ons down by the bottom yoke and as much by way of gas flowing improvements, hot cam (Viper?), raised compression, tuned exhaust, better carburation etc etc, I bet you can break the 90mph barrier. I've never owned a Velocette but a friend had a Venom which was a superb machine. They're very well made and, I expect, pretty tuneable.

People used to race Nortom 16Hs after the war and the best used to get close to 100mph, and they're side valves!

My only tip is to read Phil Irving's Tuning For Speed - very relevant as written when people were doing exactly that with just those kinds of engines. It's a very readable book too.

Much like my approach to speaking French (or German or Spanish), where sometimes I can get a roughly-appropriate noun and present-tense verb into something like a sentence so I count myself as "functionally fluent."

Returning from the outback to batteries:

OK, that gives the possibility of having a huge battery. For a direct comparison where space is a constraint I went to the Autozone web site (a large chain of auto parts stores), entered the details of my Ford F350, and got a list of 11 batteries that are supposed to fit. "Normal" batteries ranged from 650 to 850 CCA with a correlation between price and capacity ($70 to $190). There also were four Optima batteries in the list, 2 ea. at 750 and 800 CCA ($225 to $275). That is, although much more expensive, an Optima battery wouldn't supply any more starter current to my Ford than a conventional battery.

Part of the price difference is due to Optimas being "maintenance free" AGM whereas the low end batteries at Autozone are simple lead-acid. Five minutes of "research" into this doesn't tell me how much of the rest of the price difference is due to advertising terms like Spiralcell Technology® and Pureflow Techology™, but a CCA is a CCA. Maybe even though they deliver the same number of Amps for 30 sec., perhaps an Optima would last forever and thus would be a better deal for that reason. Or maybe Trevor drank the Spiralcell® Kool-Aid. I don't know, but I do know that I already bought a replacement battery a few days ago and so for present purposes the issue is moot.

That's simply because battery capacity is lower as temperature drops and CCA ratings are at 0 oF while MCA at 32 oF. Different ratings make sense because Canadians still drive cars at 0 oF but not too many use their motor boats when the temperature of the lake drops below 32 oF.

[quote=dave - NV]And speaking of mag fitting .. What is a good seal between the mag and the case to prevent water and grit to enter the mag? I've used a thick O ring in the past glued onto the face of the mag housing with questionable results. Cut some from thick gasket material?

My mag has a cork gasket that is about .060 in thick. The retaining screw of the dynamo compresses it to affect the seal. Not being able to find a source for the gasket, I obtained some rubberized cork material and cut my own.

I won't pretend to know about your engine. From what I read, it is only suppose to have four studs out of the ten fasteners that hold down the head. You have said you have six. On the last two that are still in, could a washer have been deformed into the threads of the stud(s) as Gavin has suggested by the use of thin ones.
My eye are not as good as they used to be, so using a bore-scope has helped me looking into tight spaces. Mine is a hand held one, but I see that bore-scopes are available to plug into a laptop computer for a small cost compared to the hand held ones.
I have not used this method, but in other old bike magazines they have talked about using a grease fitting attached to spark plug threads and pumping the cylinders full of grease to push the head off.
