You do need to be careful not to let any blasting medium inside the air box.

BSA A10s used to bias the mixture to one side. I don't think anybody actually knew why but ISTR that a slightly skewed manifold gasket / spacer was available to "correct" it.

I made a puller from a length of 1/2" UNF stud which previously saw service as a Commando clutch compressor, a box spanner and a chunk of flat bar (also from the clutch compressor). Turned down to 7/16" for an inch at one end and screwed into the top end of the bearer rod, it actually slid...

Yes, leaving it as a rigid has been suggested but I won't admit defeat (yet.....) In fact, I deliberately chose this model for the plunger suspension. I did try the grease gun but the threads of the nipple are so sloppy the grease just squirted out of the side even with several wraps of ptfe tape. S...

I'm starting to get down to some work on my 1952 Norton ES2. I did have a feeling the rear suspension wasn't working and have discovered that the alloy slider on at least one side (all I've looked at so far) is seized onto the bearer rod. After slackening the pinch bolt and freeing the taper the bea...

I would imagine Achesons produced them and either overprinted the Ariel logo or gave them to Ariel to do. I wouldn't actually think colloidal graphite was an ideal substance to use when running in myself.... Interestingly, Achesons still exist as a subsidiary of ICI and produce something called Aqua...

You should (theoretically) use 5K resistor tyes to avoid radio interference although this is a lot less (maybe nil) with FM rather than AM radios.

I used the dark red NGK hard plastic ones with rubber seals. Maybe not original but better than those reproduction rubber ones.

Remember main jet only comes into play at wide open throttle so it's usually not a problem to go too big. Too small on the other hand can limit the flow through the needle valve at smaller throttle openings.

Yes, there are a lot of fakes. I've just reported a 30s side valve Norton starting at £1.22........

I always add separate earth wires on all my bikes as especially when bits have been painted /powder coated the standard earthing is suspect.

That description from Roger is superb.
