Probably the spacer sleeve and bushes coming into contact with each other on full extension, due to poor damping, a design fault.

Singles / Re: Any good pictures of Sapphire Blue (063) Bikes ?

I found the Sapphire blue supplied by RS to be much to pale a shade.

Always hard from a photo but below are 2 shots of a new old stock BSA Sunbeam scooter tool box lid in finished in Sapphire blue.

All the books show needle in position 1.

But you will  need to experiment for best settings, using the Amal tuning guide.

2 stroke concenric have a pilot jet which screws in (but not the bushed one), so did some early 4 stroke versions.

Later 4 stroke versions had a bushed non removable pilot jet and did not use a screw in one (new premier concentric now has a revised pilot setup).

Beig the Spanish made item will also explain the lack of O ring, had one like it some years back.

You can find it in the Amal link posted earlier.

To get the best from your bike I think you need to change that carb.

Some gear oil specifications are not recommended for boxes with phosphor bronze parts - bushes.

Suggest see the Morris website for classic oils and read the technical information for the products they offer.

Using Morris 20/50 in my A10 needle roller box with no problems. Have also used Halfords gear oil to GL4 spec with no problems.

The need to show insurance to tax stopped at or near the time the paper tax disc stopped being issued.

The form used to apply for age related plate, the V55/5, is an application for first tax and registration of a used motor vehicle. You need insurance to tax a vehicle even though it is free.

The main thing is that you already have a V5C.

Just checked my V5C - only got date of first registration. No space for date of manufacture. If the 2 differ the manufacture date is usually on the front under "special notes"

Try the post office is good advice.

If your frame number prefix was not issued by BSA you will probably find it cannot be dated.

Your carb was set up with pre 1969 parts. Then the carb was improved and the needle, needle jet and jet holder were changed. The needle went from 5.79cm to 6.74, the jet went from 1.74cm to 2.06cm and gained a cross drilling and the jet holder went from 1.9cm to 2.2.

You cannot interchange the parts you need a jet and jet holder to go with your new needle. The pre 1969 parts are obsolete.

See this link from Amal which explains all.

Frames not quite the same, differences to take twin/single engine  but foot rests are.

The nearside parts changed for both for 1958 on.

The V55/5 only asks for an MOT certificate "where appropriate". IF you bike qualifies for exemption under the new 40 year rule then complete a V112 you dont need MOT to apply to register it. If your bike does not qualify under the 40 year rule then an MOT is required to register it.

You could try R K Leighton for a seat which fits.
