Dished pistons were no longer available back in the 1960s. It's hard to imagine there are still any Flashes that still have them. Flat top 7.5:1 are absolutely fine.

Granny and eggs comes to mind but are you absolutely sure you have set the timing at TDC on compression? We have all been there...

Very true. Classic oils have higher levels of ZDDP than synthetic oils. Synthetics are excellent but are slightly compromised by having to avoid contaminating catalytic converters in exhausts.
Multigrades are fine, just don't prolong the oil change interval over much. In fact, the same advice applies to monogrades.
If you intend using synthetic oils, make sure your bike is well run in first.
There are strong opinions out there. As an old lifelong motorcyclist once said, if you were stuck, you would be happy to use melted butter.

Castrol XL is still available. I have 20 litres in my shed. Have a look at Morris lubricants website. They have oils for every possible use. My rule of thumb is straight 40 for roller big ends, 20-50 for plain big ends. Many people use multigrade for everything with no problems. It's a big subject with many strong opinions. Essentially, if you use a reputable oil and change it regularly you won't have any problems.

You could pick up a Smiths magnetic speedo much cheaper than a chronometric.

We all have tales of regret. The DBD34 I turned down for 80? The Vincent I turned down for 120? The Ariel VB 600 I turned down for 6. Even the Ariel 500 Red Hunter I sold for 80.
The good news is we still have the A10 (45) and A7 (also 45) so can't really complain. Now why did I pay 5250 for a Velocette? 

Twins / Re: A10 rev counter timing cover

The timing cover rev counter drive catches your ankle. Given a few years, you almost get used to it. That may explain why it was changed to an oil pump drive.

Smith's hasn't made an 8 day clock for many years. I found mine at an autojumble - possibly your best hope.

I suspect the nearest you will get is the Smith's 8 day chronometric clock. A fine match for the chronometric speedometer and handy for these longer rides...

Twins / Re: A10 Carb

The stamp these days means nothing - the carb will most probably have been rebuilt several times using any serviceable body. How it works is the important bit.

Singles / Re: A65 pistons

7:1 is absolutely fine for present day petrol which is rather lower octane rating than was around when A65s were produced. You won't notice the miniscule power loss.

The Star and Garter / Re: owning a British bike?
« on: 11 October, 2017, 14:41:53 »
An old bike is only as good as its last rebuild. If it was done carefully your machine will last for years and years with minimal attention. My Star Twin has never failed to get me home in 40 years of use and abuse and like Steve, I would happily take it anywhere. It is still everyday transport and used for time-critical journeys where I have to be at a certain place at a certain time.
The reputation for unreliability was built up in the 1960s and 1970s when the bikes were run into the ground and bodged by unskilled youths who thrashed them mercilessly. Guilty as charged, Your Honour. 

Twins / Re: A65 cylinder flange cracking?
« on: 07 October, 2017, 21:10:55 »
Yes. An A65 I bought many years ago had the barrel flange cracked. All the nuts seemed to be torqued up OK.

A can of worms may well be opened. DVLA seem to be going through a somewhat inflexible phase just now. Just possibly they might be helpful OR you may have to go through the whole tedious process of applying for an age related number - and losing your original registration.
Bring back helpful local offices.

The Star and Garter / Re: MOT changes for historical vehicles
« on: 18 September, 2017, 06:34:43 »
I think it is aimed at the Series 1 Land Rovers with coil springs and a V8 engine - nowt but the body panels left of the original. And claiming historic vehicle tax exemption. Will modified vehicles lose their tax exemption? It would make sense.
Locally we have 2 MoT testing stations. One does the fine tooth comb bit - even putting my 1913 Douglas on the brake test rollers. The other treats the elderly vehicles with a bit of sympathy whilst ensuring they are roadworthy The first mentioned MoT station was going to fail my Series 1 Land Rover on missing sills. Series 1 Land Rovers don't have sills.
It's this huge disparity in dealing with older vehicles that is indicative of the need for MoT exemption.
