Singles / Re: Petrol tank internal cleaning / sealing
« on: Today at 10:42:31 »
If there is a lot of rust then chuck a hand full of screws, nuts etc in and shake to loosen the rust. The last screws etc can be fished out using a magnet on a stick.

Then fill with a dilute (around 5-10%) solution of phosphoric acid and let it stand (I go for overnight), empty, rinse well with water, this will neutralise any remaining rust.

If the tank then leaks you can consider a liner but if it is sound I would steer clear of liners.

Singles / Re: Cylinder through bolts
« on: Today at 09:24:48 »
I have seen the same problem on a friend's bike I worked on, the captive end just unscrewed when we tightened the head bolt and fell into the crankcase.

I have also had examples where the captive section was screwed on with a left-hand thread which at least meant it also tightened when the bolt was tightened into the head. The problem would then come when you undo the bolt!

It is just a cheap was of making these bolts and very unsatisfactory.

the washers need to be a very snug fit, inner diameter 5/8 inch (15.9 but realistically 16mm)

the adaptors available from Kiddiminster and others are not suitable for the earlier box. You are stuck with the 6 spring with the 46-48 box.

That looks like the primary drain plug. If it is leaking frm there you could try checking the seal (fibre washer?). Alternatively that is the lowest part of the inner primary case and any oil flying out from behind the clutch is likely to end up dripping off there. If the oil is originating in the primary, it is now coming out because it is being thrown about by the chain when the engine is running.

Singles / Re: B31 (1954) - how to fit side stand?
« on: 29 April, 2022, 07:20:43 »
that is a lash-up to limit the brake pedal movement upwards. Temporary until I can make something less obtrusive.  ;D

I have the clamp on type of side stand on plunger M21 and B31. They work well without welding (although that is a good option) as long as you get everything clean (degreased) before clamping. The angle of lean should also be only enough for it to work, the more lean the more pressure on the clamp and the more likely it will start slipping.

+1 for Julian.
The stand should be almost vertical in use. Yours has a fair bit of wear on the mounting lugs, stops, etc and it does look like the feet have been added to to compensate so meaning you have to lift higher to get the bike on to the stand.
You neeed to remove the stand and find out where the wear is and after fixing that you can grind off the excess on the feet.

I had the same problem with my B31.

I'm not familiar with the front wheel drive but I have heard of this problem before on the WM20 website. I suggest you post your problem there and I'm sure you will get an informed answer. They have helped me no end with my bikes  ;D
