I used to "recycle" the six hole washers by cutting them into three pieces, so there were other edges to knock over to secure the bolt head. This of course depended on the area around the hole not being too damaged. However, drilling and wiring the bolt heads is a better course of action. ...

If it is free to rotate, you will eventually end up with little drive and a lot of noise! It should not be able to ride over the top of the sprocket cam, although different spring lengths (including a worn/old spring) might allow this to occur. I used to tighten the nut until it bore hard against th...

I had a problem in the past with blowing from the head/barrel joint when mating a VHA head with a new make alloy barrel. I think the head had been lapped in too many times, as there was alloy to alloy contact between the head and barrel, rather than liner spigot to head contact. I cured this by dela...

I can't answer Q1 or Q2, but would advise the piston is of the type used in the wartime WNG model, and if using it with three compression rings, it is advised (elsewhere on the forum) to use the earlier oil pump with a smaller feed plunger, to avoid oil making its way into the combustion chamber. I ...

Thanks for the feedback, I'll try using a hybrid synthetic/vegetable oil, and aim to remove as much of the current oil as possible by removing the sump plate as well as draining/cleaning the oil tank, and then keep a good eye on the oil tank return filter to see if anything untoward appears.

When I purchased my all alloy VH 2 years ago from the widow of a club member I knew, she gave me a small folder of information relating to the bike. He was into competition singles, and amongst the notes was a comment that the bike was run on Castrol R oil. Having eventually sorted out some incorrec...

I had PM'd you, but message has not been picked up yet.

I have now looked at two dynamo ends, believed to be NOS, and both have a 2BA thread to retain the end cap. They are the latest type of end, for use with the one piece metal end cover, so whether the thread was changed to suit the more robust endcap design,I do not know, although looking at a used e...

Perhaps it is a reflection on the state of many threads I have encountered in this area that a 2BA screw will invariably fit, even if it was originally a smaller, finer thread. I will take a closer look at the best condition end I have, to see if I can ascertain exactly what the thread size is, but ...

It's 2BA, commonly available. I can supply a length of 2BA studding (cut from a longer bolt) plus a couple of nuts, for the cost of a stamp.
