I have roadriders on my B31. The grip is amazing wet or dry and the handling sublime.
If you square a rear tyre off you are not cornering fast enough

I make all my own cables. I always use nylon lined outers, they just need a squirt of WD40 occasionally.
I fit angled tubes to carb tops to stop the cable kinking, I also fit angled tubes to the twistgrip so the cable runs close to the bars instead of dangling
I buy the components here

I used to have a Cub with a blind grommet there, It was for access to the clutch cable

An insecure seat is an MOT failure as well as extremely dangerous

Will it still move carrying all that weight? I prefer to do my maintenence in the workshop. I carry an RAC card and mobile phone for emergencies

4" badges with BSA and a star background are available in Black, Green (A7SS) and Red (Gold star)
I have the black ones on my B31 with polished alloy tank, they look rather good

The red badge with the 3 rifles was fitted to all B31/33 with round badges. The Bantam badges with BSA and a star also fit

I would only change one thing.
I would fit a throttle cable with a bend at the end so it runs parallel to the bars instead of dangling

Via the condensor

The ignition coil body needs to be earthed (connected to frame) to complete the HT circuit.

No it doesn't

Hi, not running but I have managed to get a spark, I added an earth lead from the coil to the engine and also found some perished wires coming from the alternator which I wrapped insulation tape around as thought they may have been dragging it down, I'm planning to put a teaspoon of petrol down the barrel tonight to see if she will fire over.
Thanks for your help.


There should be no electrical connection between the coil and earth. The coil circuit from the battery - ignition switch - coil - contact breaker / condensor - earth

I had a wet sumping problem on my A50. I put in any anti wet sumping valve. 35 ish and a fairly easy job.  No more wet sumping.

I was against the idea to start with, but when I mentioned it here, several guys gave me positive results so I went for it.

It easy to see that it is working by watching the return pipe in the tank.

Worth a thought???

The A50 and A65 have an anti wet sumping valve from the factory. It is the ball and spring behind the oil pump. The valves that fit between the tank and the engine could cause oil starvation, pumps do not like to suck

BSA didn't think about that. One way is to hold the brake on and use a deep socket and rattle gun

Before you start stripping it down, put it in gear, pull the clutch in and press the kick starter. It should turn the rear wheel, if not the problem is with the kickstart mechanism, if it does then the problem is the primary drive.
Remove the plug, put it in gear and turn the rear wheel, if the engine does not turn over the problem is the primary drive

Sorry I cannot agree with you, thick treacle like oil is not a substitute for good surfaces and gaskets.
There is a common misconception that thicker oil has better lubricating properties. Bullshit, thinner oil reaches the bearings faster. Film strength and shear resistance are more important, additives such as zinc improve wear resistance on high pressure areas like cam followers.
