Re: Grease box

Concerning the amount of grease, I read that the CP was filled 1/2 with grease when new and the content should not fall below 1/3.

Re: fun clip

Back in the days when you had to remove all the insects from the goggles after a day's riding, on a small country road I saw a small dark cloud ahead of me. I expected midges. It was a swarm of bees. It felt like heavy rain. Most bees died on impact, except for those between the open helmet and my c...

measurements single lobe cam followers

I have a pair of single lobe cam followers that must have been refaced at some point. One pad looks suspiciously thin, but overall measurements are almost the same as the other follower. Are there any measurements of new cam followers? I vaguely remember having seen a drawing.

Re: float chamber lock screw

For future reference: It is 6BA. The later top-feed lids, including those sold by Drags, have larger lock screws, but I think they are all post-war.

float chamber lock screw

I have a top-feed float bowl for an Amal 76. The brass lid has a tiny hole for a lock screw, which is missing. I checked the Amal catalogue and the part number is 3319 for a "1/8" Lock Scew for Float Chamber Cover". Can anyone help me with the thread size for the missing screw, please...

Re: Flexible petrol pipe

In the RH500 road test from 1937 in the document repository there is a close up of the engine. The pipe looks like the second you mention, Brian. But it's a low-res black and white picture. The 1937 catalogue specifies a "large bore tap" without reserve for the Hunters. In the picture abov...

Re: Flexible petrol pipe

In catalogues (e.g. 1936) Ariel specified "Petroflex" pipes for the Red Hunters, but not for the de luxe singles. I don't know whether there was really a difference. In period pictures those Petroflex pipes look like the modern braided pipes without any coloured stripes.

Re: SAFER RUST REMOVER

Yes, there is no way to drain it through the filler neck. The panel tank is really a complicated construction. Access to the other half, just for checking what it looks like, is really tricky.
