Re: Lodge plug

I couldn't agree more Brian. I do use modern plugs, but only Bosch ones, because of the poor experiences I have had with Champion and especially NGK. I use the old Lodge plugs for exhibition purposes - and as the backup spares in the toolbox for when the modern plugs go down.

Re: 1948 KH

Hello Brian,
You have the wrong inner primary case - helpfully placed at the bottom of the photo. This is one from a single cylinder Ariel. The one for a KH has a step in the rear edge which sorts out your problem.

Re: Concentric carb on a Mark 1 square four

See:

about half way down the page. Have you got the slot in the gasket? It takes the undoing of 4 screws to check.

Re: BA Gearbox Problem

Look at the two pins which govern the selector mechanism, one of which is the end of the bolt which goes in through the kickstart cover. These pins can develop flats on them after time, which reduces considerably the overall movement of the selector. Look also at the plates which these pins bear upo...

Re: rigid crank versus swingarm crank

Wiser men than me - Bob Brassington for one - have suggested that the balance factor is different for rigid / plunger and swinging arm frames. That said, my original 1957 NH used to destroy cycle parts if ridden at 55mph. An extreme illustration of this was the rear section of the rear mudguard whic...

Re: New member, '52 VH500

It looks like a super buy. Further to my last post, advising you to clean the sludge trap, can I suggest removing the oil tank completely from the bike and cleaning it out with petrol and a bottle brush or similar. I think you will find a black gunge at the bottom which is best removed at this stage...

Re: FOR SALE : 1955

This looks like an excellent buy. Take the oil tank off and clean it properly, take out the sludge trap and clean that, get the mag rewound by Tony Cooper, fit new tyres and tubes and you may well have 10 years of trouble free riding.

Re: Armours fishtail exhaust

I have fishtail silencers from the Czech boys on my Square four. These have no baffles whatsoever in them so I have fitted Armours "pepperpots" in the ends of the exhaust pipes. These "pepperpots" are very similar indeed to the baffles in your silencer. The Square goes very well ...

Re: Pre 56 top yoke.

Drags are correct. The alloy yoke has 3/4" holes as standard. What you are missing are the stepped tubes which screw into the top of the stanchions. A glance at the parts book will show you these.

Re: Foot peg

Minor clarification to my previous post. I have completed restoration of the rear footrests of the Healey, not of the complete bike! There is still some work to do before the bike is completed.
