Re: 1936 VB

I don't think that is an Indian tank. All the indian tanks I have seen have the curved top profile used from 1938 onwards. This has the flat top profile used to 1937.

Re: 1938 4G; Is it positive earth, or negative?

It's whatever you want it to be. Mine is negative earth, because all my bikes are to prevent confusion. Get the bike going and see what the output is using a suitable voltmeter. If its the wrong way round, simply reverse the field coil connections and it will be the right way round. At that stage, y...

Re: MO1 Magneto Question

Bob,

If you want to borrow my puller, let me know. I should be passing your area on Friday but the Royal Mail are pretty reliable in any event.

Re: Square 4 wheel rim size.

I think Chris might have found the only reference to use of a 4.00 x 19 WM3 on an Ariel rear wheel. I can't find one in my books, but I don't have the 1939 book Chris refers to. Presumably it will fit, or can be made to, but the speedo will be slightly inaccurate, unless you have a front wheel speed...

Re: Powder Coating frames !!!!!!!

I am interested in why you think powder coating is bad for the frames. I was sold on it when I bought my MkII with a frame which had been powder coated some 30 years previously and, as a result, was in perfect condition despite being used intensively by a rider whose pride was to say that the dirt f...

Re: Front Forks Mk 1 Square Four

Please can I correct you Keith. BSA fitted Ariel front forks, not the other way round. Son Rob has the Paul Goff kit fitted on his VH so over to you Rob.

Re: 1938 ARIEL SQUARE FOUR SOLEX CARB

Don't spend too long on it Ralph. Once the bike is on the road the carb is not too noticeable and usually has a certain amount of oil on it anyway. If you rechrome the choke lever bracket and the petrol pipe, you won't notice the carb colour at all.

Re: NH camshaft in W/NG

Ray, Having looked at the very same F cam whose photo appears in the article, it is evident that the two lobes are slightly different with the one closest to the gearwheel having a broader crown. The article states (and notes on my cams confirm (unless I got it all wrong)) that the lobe next to the ...

Re: Brackets on rigid frame lower rails

Sorry to have to add to your answer Lee but you need to notice the difference between the two mountings. The one on the left side of the frame does indeed take the square head of the exhaust mounting bolt and its U shape prevents that bolt from turning as you tighten it up. There is a lot to be said...

Re: MO1 Magneto Question

Removing the outers is usually all too easy. I have had more than one see fit to come loose without my permission. It would surprise me if you couldn't remove them by means of a jeweller's screwdriver suitably and carefully applied. The paper gasket gives you the room to get the tip of the screwdriv...
