Re: Club Rods are tight

Anyone else has this problem? What should my next move be? Hello John, Yes, I had that exact same problem. It has been a few years now and I can't remember exactly but old crankshafts have a different radius on the journals than newer ones. I'm a bit too busy right now to dig into my records for th...

Re: Burman rebuild

Wade,
Don't some Vincents use the CP box? I remember their club spares supply as being quite comprehensive. You could give them a try.

Re: Tank rubber knee grips

Hello Alan, I don't know when Ariel changed the style of knee grips. I believe the knee grips on my 1950 NG are original. The one on the right is the same as the lower one in your photos with the John Bull words and numbers moulded into the lower left. The left hand one, as shown in the attached pho...

Re: BA Gearbox Problem

End float of the selector drum is not easy to adjust and the question always becomes which way does one move it, so I've just put up with it. Hello Nev, Thank you for the reply. I've measured about 13 thou of end float for the selector drum (camshaft) without a gasket and I did have a gasket fitted...

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 up...

Re: BA Gearbox Problem

You can get wear on the pins that are in the selector forks and wear on the fork faces themselves and excessive end float. Anybody have any specs for camshaft and layshaft end float? I think Waller states between 1/32" and 1/64" for the mainshaft but I don't think he mentions the two othe...

Re: Removing old tank sealer

Good! You're lucky. I guess times have changed. Why don't you buy a litre and try it? Don't neglect to take proper breathing and skin protection precautions. I understand it can be dangerous to one's health.
