Re: 10 w 40 oil

I wouldn't use anything with less than 50 at the top of the range and I'd also steer clear of 'modern' oils for an older engine 'cos they're cutting down on (eg) anti-rubbing additives. I'm going to use one of the 'classic' 20-50s in mine, certainly with an SAE rating no later than SF (Comma is SE) ...

Re: VH Valve question

Sack 'em and sue 'em. I can't see how they can pass an opinion on the end caps without having the engine assembled, valves 'made too long' by end caps would mean that fitting the end caps lost all the tappet clearance. The only time I've seen that happen was when the numpty doing the valve seats had...

Re: VH rocker box gaskets

I'm still working through my small stock of original gaskets, I'd call them thick but not particularly hard, they do sink initially but then stay pretty consistent (and with care I can generally re-use them several times, which is just as well as I've only got a couple left). They're grey and graphi...

Re: Square four rear brake

Bill - the brake rod needs to be bent, it's a feature of the plunger rear brake setup (not just squares) which had a few issues with 'self-sevoing' and consequently several changes in the method of operation. There's an article in Cheval Sept 2015 with some analysis of the problems ('Ariel Spring He...

Re: ariel sq4 duel seat !!!! or is it

Keith: I think there are several different brackets available for that type of seat (which looks very similar to the one I fitted to my rigid VH many years ago); it looks like you've certainly got something wrong at the front as it's too low - even on the later Squares it's much higher, check out so...

Re: Correct Tyre Specs for Huntmaster FH

Nick: I became a firm believer in modern tyres when I changed to more up-to-date rubber (Bridgestone BT45s) on my BM and it absolutely transformed it. And I reckon my Ariel looks fine on Roadriders but I'd sacrifice tyre looks for tyre performance any day. (Can't get BT45s in a 19-inch rear or I'd p...

Re: Correct Tyre Specs for Huntmaster FH

Oooohhh - tyre thread! :D You should have 19-inch rims front and back, I think they're both WM2 which would usually be a choice of 3.25 to 3.50 - most people put a 3.25 on the front and a 3.50 on the rear but the rim will accommodate either. Don't use vintage tyres use modern ones! (Which might mean...

Re: Australia's fastest Ariel: 127 mph on a 1938 Red Hunter

The Motorcycle Mechanics article was reproduced in Cheval Jan 2013, with an intro in the Dec 2012 issue.
(Very interesting although possibly not as technically informative as some of the threads in the forum :D )

Re: '57 Huntmaster - Rear Wheel Hub

Looking at the info on the Drags web site the Ariei/BSA sprockets are different (42-tooth BSA vs 47-tooth Ariel, also a few other things - mainly on the sprocket side, so it might be more than just the number of teeth) I spoke to John Budgen just after Bunners bought the last one. JB was getting his...
