Dennis Jones article

Nice....
Youre going to make me dig out the different article i have now

[Michael Moore]

Here's a couple of shots of a head casting for a Jones single being machined by John Stevenson. This was done in modern times and I think he had a couple of of Jones' bikes for awhile.

cheers,

Yes Husa that was exactly the bike I was talking about!

An excellent road machine concept, expensive maybe, not a racer and very good, but as always, if it's not the fashionable thing to have then it won't succeed.
Unfortunately it's not the people who know the finer details of machinery or are expert riders, who dictate the terms, it's more the short sighted "image" guys with fat wallets looking to buy this year's something or other (anything to attract attention) who actually make or break a company!

.... and, yes of course I'm a silly negative old fool ..... as usual!

You and me both, mate. You just described the Harley-Davidson philosophy.
Why invest in technical development when all you need is leather saddlebags and a spud-sound (you know that distinctive H-D idle: potato-potato-potato-potato).
Harley even tried to patent their sound, but they didn't succeed, so now most Japanse marques offer 45° V-twins with the same firing order and with tenfold reliability.

Returning to your 'excellent road machine': that narrow-V six-pot Horex is not really my cup of tea. It violates KISS: too heavy, too complicated, terrible piston shape.

I know it's not HD technology (really meaning the colour of the saddlebags), or anything ever so refined, but this one makes VW's Dieselgate look pretty mild really.

Pretty sure that all these were 4 strokes:

Today, a great pall of black smoke combined with high pitched screams (70,000 rpm or more) were seen and heard over the industrial suburbs of Perth in Australia and simultaneously over the green fields of New Zealand's Waikato. (Said to come from top secret experiments with HCCI and a new type of throttle).
Could these incidents possibly be connected? - no doubt we will find out soon.

NB: we have been assured by the experts that it is very unlikely to have been caused by a two stroke engine.

UPDATE: There are also unconfirmed reports of links to the Netherlands.

Good reason to carry a CO2 fire extinguisher - empty it into the intake and smother the damn thing.

Something like that happened to my brother-in-law's truck and as far as we could work out it was running on the contents of the sump sucked through a bad turbo seal.

Most of the 2T Detroit diesels I worked on had spring loaded flaps poised over the blower intake. Knob in the cab pulls the pin. Was maybe 2-3mm thick plate, and I once had occasion to use one on a 671 on a dyno. It came out later looking like an ashtray.

Problem is Willy that the crankshafts and 70 mm con rods keep breaking, however the STRIKE Ozzie made piston has survived through all the testing to date
