No ammeter on OIF A65 headlight shell.

Should not really need it but if it leaks you could use some.

I would renew the o ring unless I was sure it was good.

The small level screws are usually OK with a new fibre washer or a dowty seal washer.

For things like fork drain plug washers just measure it - you should be able to match them cheaply on ebay for a small sum and have enough to last for years. The later A65 parts books do have some thread details but also remember that the fittings in some locations - fork pinch bolts head bolts etc - are high tensile steel.

Looks like access to the plug could be difficult - this extract from factory issued parts bulletin G31 of March 1965 shows that  the spot facing was increased in diameter to enable a box spanner to be used to remove it.

It will depend on which lobe of the cam ring and which cylinder you time it on.

Before buying a tool I suggest check if you can get a drift on the race from the other end of the headstock tube and simply tap it out.

Some of the repro races do not have the threads.

3/8 inch drive sockets can be quite useful, 1/2 inch drive often too thick for some of the spaces on our bikes.

Possible someone put a cable for an 8 inch TLS on it.

Contrary to what you have been told these brakes are excellent, light and powerful and by far the best of the BSA drum brake.

Below from the 1969/70 workshop manual detailing how to adjust the tie rod.

There was a change in the distributor in 1963. From 15 degree to 10 degree.

But in the past 54 years it could well have been changed.

The service sheet gives some detail, though I would not use the retarded timing figure they give.

It has, helpfully, had the Lucas part numbers added.

The 3 arm method is difficult - the shoes slide so may not both be in the best position.

Turn the plate over and adjust the rod so that the end of shoes are on the flat part on the cam. When bedded in dont adjust the rod as the shoes will then need to bed in again.

The switch, when fitted, is on the cable and cannot be removed (or added) without removing one of the nipples.

These brakes are also quite spongy - you can usually pull the handlebar lever back to bar when bike stationary, but try it on the move, when the shoes slide on the brake plate, and you will find it is a superb brake.

Some pattern shoes may not be quite the same dimension as the original items.

Cables are a sort of average, the originals were made to suit Amal levers with  7/8 inch between centre of cable nipple and centre of lever pivot screw, many repro levers are 1 1/16 centres which does have an effect on cable length.

Cables which are too long overall dont help.

Many of us make our own cables so that they are always the right length for our bike.

Worth checking that your centre stand will still function - will be long enough - with larger wheels.
