Impurities are cause of pinholes. Usually.

If the pin holes are as small as the filter mesh, just let it be. One thing is certain, not polyester. Had an at least 30 year old quick fix with that on my Manx Norton that started to leak.

Singles / Victor Special transfers.
« on: 09 June, 2021, 11:41:35 »
Bought a fairly decent running -B44VS yesterday. When put it aside my other -70 B44VS, I noticed that the tank transfers was different size. One was originally sold in USA and the other one in Sweden, if that matters.
#1 size approx 177x57 mm. #2 size approx 123x32 mm.
Which is correct, if any?
Second question. I believe that the B44VS I bought new in 1970 had a white BSA logo on the tail end of the saddle.
Half a century later, do I remember correctly?

My matching number 1970 VS starts with PD. Whatever that means.

It might be that the tyres are worn flat. You say 60% worn. If most wear in the middle, it will affect handling quite noticable. Experienced that on a modern Ninja. After a lot of long distance riding at a legal pace it handled quite bad at a track day.

Bought my first Victor new back in 1970. Sadly it melted in a barn fire in -83. Bought my second one last year. Don't remember any issues with them. Remember that 200 miles main road trips was quite boring. But a lovely bike on gravel roads. Sounds that an electronic ignition is a decent idea. Got a Boyer Mk IV on my B40. When done right, the Victor starts easily. Slightly different technique than on the Velo or the Vincent. Even my then girl buddy at less than 50 Kg had any problem starting the first Victor.

Living in an all metric country, I have problems with obtaining small quantities of imperial materials.
When ordering some tools from Chronos, I also bought some from them. They also has metric.

None to the left on neither B40 nor B44. Hard to tell from your picture if the left goes in or out, but I believe it's no crack.

I'm not sure that it's a crack. Looks like it is going up from the surface. It could be be from a form joint when casted. Similar to one to the right of the number.
I have the same to the right on both the B40WD and the B44VS but none to the left. Might they have used different casting models for the B44SS?

My B44 Victor Special is still happy with everything original. The B40WD came with a Boyer Mk 4, which works well. I've fitted it with a rectifier/regulator and a MC2 replacement from Paul Goff. Starts easily with or without battery.

Some minor improvement can be to make sure the nipple rotates freely in the the lever and grease it.

Singles / Re: B40 Clutch release issue
« on: 02 January, 2021, 13:43:40 »
As I'm in the process of fitting the outer cover on my B40 and have my B44 standing next to it, I might be able to answer your question.
The most likely cause is that the 7/32 steel ball is not in place. It shall be in the recess in clutch operating rack. So that the ball will push on the clutch pushrod. I think that some grease will keep the ball in place during assembly.
I assume that the clutch release arm can be moved out to five o clock.

One thing I've noticed is that many small chinese lathes can't make single point 26tpi threads. Worth checking before buying. Though most times you can make BSC threads with taps and dies.

I've used a high temperature silicone for head to downpipe on a B40WD and a RG250, worked ok. Also used it on downpipe to silencer joint on a Manx, a Vincent and a Ninja.

Singles / Re: First restoration project advice
« on: 13 November, 2020, 13:57:03 »
In my limited experience from having half a dozen old british bikes, mostly running ones, I'd say that even so called restored bikes need a lot of work to run well. A basket case usually miss some almost impossible to find parts. So I think you should consider going for a running one. Life is too short for not enjoying riding them. Yes, I'm a M.Sc. Mech. Eng. too.
At present almost finished work on a Victor Special  which I bought to replace the one I bought new and melted down in a barn fire in -83.
