There should be an oil filter in the tank but the 1958 version is very different from the up to 1955 version. It will fit the 1" hole you have but at the bottom, has a cone with a hole in the narrow end which fits over the end of the delivery pipe in the tank. So the late version filters the oi...

If you find which dealer the bike went to, and hence the likely registration authority, and if the registration records have actually survived, you may be able to make a good guess as to the registration number if it was the only Ariel registered by that dealer at the relevant time. Very few registr...

Sorry, I got that wrong. Make that 3 for me.

You should go back in to production of these Vincent. We all say that we are giving up making things from time to time but in the end the demand becomes too much. I need 2 please.

Re-whitemetaling the old bearings was commonplace about 30 years ago and presumably can still be done by those companies who re-whitemetal big end bearings, etc in classic/vintage car engines. I knew people who did it themselves but I don't think any of those are still with us.

I think the only person doing girders these days is Jake Robbins down in the south-east. You could try Chris Williams at Autocycle Engineering in Dudley who owns Percival and Webb but I think his man who used to do the work is no longer active.

As I understand it, the Morgo oil pump for the Ariel singles was produced for the Trials boys, who tend to operate at low revs. That makes some sort of sense to me. Of course, people then put the Morgo pumps in standard road going bikes which operate at much higher revs and found the consequences of...

Mid - January and John's funeral was today. The Gloucester Branch managed 5 Ariels to escort him on his last journey, a1926, 1928, 1929, 1937 and a W/NG fitted with 500cc engine and tele forks. 3 other AOMCC members were present, although not on bikes. We left the ceremony to the sound of a song, re...

Wow! How fantastic! I doubt we could achieve anything like this in the UK, even if we tried to in Birmingham.

Is the mainshaft bent?
