Re: 1939 VH for sale by auction in the UK

BMW rear brake switches (on old airheads) work completely the other way round (ie mounted behind the pedal and it's push - as the pedal returns - for off).
But then they would, wouldn't they ;) :D

Re: KH alloy head

I picked up a very usable KH alloy head from ebay a few years back for £25 - at the time I was half thinking of trying to build a KH engine for my spare frame and it seemed like a good opportunity. I had a chat with Colin Reed-Aspley (ex-Twin Spares) about it and he said there's much more KH stuff a...

Re: KH 500 stanchions

John Budgen has stanchions, bushes etc listed http://www.johnbudgenmotorcycles.co.uk/parts_catalogue.htm Paul Goff has 'equivalent' BSA parts (although the bushes are in his 'upgrade' kits, not listed separately). All Ariel stanchions/bushes are physically interchangeable but the bushes were lengthe...

Re: Correct cylinder and head?

To judge from the prominent finning above the push rod tubes that's a '54-'55 head and with a matching 10-fin barrel, so at least it's authentic for a swing-arm frame! Steel push rods for a 350 shouldn't be too hard to come by, but there are different lengths (owing to changes in cam base circle dia...

Re: Correct cylinder and head?

Hi Will - welcome! That head and barrel will be fine (even if not authentic for the year). The only issue you might have could be the push rods, if they're alloy (ie as for the alloy head) the cold clearances will be pretty big and things could be quite clattery (this point has been recently discuss...

Re: VH500 ex valve lubrication

....However I cannot see how oil is fed to the guide. :? Pete - it isn't. I think those guides are for the pre-war engines that had exposed valve gear - they are effectively the same overall dimensions so they fit the later engines with enclosed rocker gear. I've had a few for my '50s iron-head eng...

Re: Identify a ariel

Clayton - welcome to the forum. I'm not familiar with the 1930s/early '40s bikes but I've not seen engine numbers without letter prefixes or just 'X' as a prefix for a rigid single frame number. Are you able to have a good look at the drive-side crankcase between the front engine plates to see what ...

Extremely good going for Eastleigh-Norwich I'd have thought. Maybe the M25 isn't mostly a car park these days!

Re: which carb?

276 for the 350, rather than a 289 I think, Will (remembering what my '53 NH had on it).
However, it might depend which end of 1954 the bike is from - 1955 model year (so late 1954) changed to a 376 monobloc!
