Singles / Re: Frame powder coating
« on: 23 February, 2022, 10:06:53 »
Hi Geoff
One of the problems already mentioned I want to emphasise. That is the need for ensuring all oil and grease is properly removed. I had a frame coated about 10 years ago and there must have been a trace of grease or oil somewhere inside a frame tube as it ran out during the baking process and ruined the finish on the coating. It had to be stripped off and re done!

Have you considered other options ?
Some of the newer 2pack acrylic paints give a high quality finish.


Singles / Re: Crankshaft shock absorber nut

It is a lower ball joint socket for a Peugot 405 and some Citroens. Available on ebay from various sellers.

It is a snug fit and will not go on it the nut has got burrs from use of a drift. It takes a 35mm spanner or socket.
Cool, thanks Julian

All the 1948 models except the A7 used nut 65 2520, which was in use for many years on the singles ncluding on the DBD Gold Stars.

The nut on the left looks like 65 2520, the one on the left who knows.

Photo show a new old stock 65 2520, regret shown with the tool but you can see what it is like.

The tool looks interesting Julian. I had a devil of a job getting the nut on and off my 1949 B31.
Is it a tool thatís available to buy or is it one you made?

Bottom banjo removed and drilled to match the top. I managed to remove the bolt once I had loosened the three bolts that hold the front of the inner primary to the crankcase. This gave me just enough room to remove it. I might shorten the bolt slightly when I refit to enable the bolt to be removed in future without having to loosen the primary case again.
The small hole (same as my feed banjos) was around 3/64" but the large was 5/32", if not slightly larger, but I drilled the bottom one to 5/32" to 'match'. I measured them trying different drill bits in which I measured with a micrometer. I had to poke the drill down the main body of the banjo bolt too to open that up to 5/32" as well. I quickly cleaned up the 45 degree sealing faces on the lathe as they were quite stepped and rough feeling. Hopefully it's all sorted now!
Letís us know if it solves the problem - for future reference.

Interestingly Poiseuille's law states that the potential flow in a pipe or through an orifice is proportional to the radius of the pipe/orifice  to the power 4 .
So a pipe with a radius of 2mm will have 16x the flow rate of a pipe 1mm radius!
Hard to believe !! and we would have to assume pressures would be equivalent to test that.
So you what Iím saying is wouldnít need to open up the lower oil drain much to make a lot of difference.

When this principle is applied to carburettor jets and especially partially blocked pilot jets  and worn needle jets it make you realise that very small changes make big differences.

Well Calum at least youíve found the problem. I must confess that I drilled out the apertures on all those bolts on my B31 as 1/64th seemed to me to be too easy to clog up with a bit of debris. I did open up the lower ones more so. I havenít found it to flood with oil yet or smoke. If it does smoke more as time passes Iíll renew the rocker box ones, they are easy to get to.

Singles / Re: Aftermarket indicators
« on: 20 December, 2021, 15:07:04 »
Hi Drew
Ive fitted indicators to all my old bikes now. On my B31 rigid i opted to use Paul Goffs compact indicators with fitted LEDs. I think there are a bit less obtrusive on the smaller bikes and are not really out of place from a style point of view. I have used a left sided combined switch on the handlebar, incorporating the indicators, dip/full and horn ( as on the later Triumphs T120/T150 etc) on mine

I look forward to hearing your findings Phil, we all learn from these things.

Hi Phil

I can not see how that could be grease. From what i can see from the tracks and the way its run its got to be oil. I would be convinced by the way it feels to touch under your finger.
At these temperatures (? 5 deg C ) in the garage this time of year grease would feel very waxy and firm under the finger but oil will still run and actually look like oil and glisten on the finger.
It looks like oil from the fork to me.

The Star and Garter / Re: Yer Tiz new BSA
« on: 05 December, 2021, 10:09:23 »
I think a new 650 single is a great development for this rebrand. Yes its not a Ďrealí BSA but Triumph owners went through this angst with the launch of the heritage Bonneville models 20 years ago.
It looks like a nice bike and if it goes and handles well and has modern reliability and service it will fill a gap in the market.
I for one wouldnít want a 650 twin ( I have enough of them already ) but a 650 single perhaps so. Probably really easy to service too.

Hi Phil
I suspect youíll need a new one. If its the original one from 2011 its done well!
I use the gel mat batteries now such as Motobatt. Ive found they hold their charge in winter much better than the traditional ones.
I expect youíll be able to charge it and it will work for a while, but if its already 10 years old I cant see it will have much life left now.

I think its wise to take the plug from the bottom of the carburettor and see what falls out.
Also undo the banjo bolt on the carb and see how much crud is in there?
Next to consider whether any fuel in the tank is worth keeping?

Thatís a great looking machine you have.
How long is it since it has been running?

Hi Phil

Iím not sure it should come through both holes EQUALLY as they serve different purposes.
If you spray down the air screw hole and block off each of the exits in turn then i think youíll find a good jet should emerge from each hole in turn?


The Star and Garter / Re: Waiting for a V5
« on: 28 October, 2021, 09:49:11 »
I bought a bike a while ago and forgot to chase up the V5.
After about 6 months I hadnít received it. I phoned DVLA and they said it had been sent weeks ago. I hadnít received it and must be Ďlost in the postí.
I had to pay for a replacement that arrived within a week!
