    They suffer from massive bore wear just below tdc where the piston rocks, even just as an air compressor.

    Yeah, I had misgivings about how good that thing would have turned out! I'd say that the transition from one ring to another (as I see it) would have been akin to using a scraper on the bore, - looks good though!

    Yes, windscreen with wiper etc. but no roof,( earlier uglier model ) not sure what year but had been used on a golf course for years without the fairing etc. on it. - they are all the same basically but later ones have different front suspension, some models have teleforks, early ones leading link, the newer ones use trailing link (as in most scooters) and have 'prettier' plastics changes.

    Don't want to get too far away from the original theme of the thread, but worth a look here:-

    Not that I ever wanted to race it of course, but looks like fun - note the ordinary three wheelers don't get around as quick as the Gyro, even with it's narrow track!

    I believe it is a narrow gauge, dad had owned this tractor since about 1995 I think, did it all up as new, paint, stickers and everything. I thought it came from Feilding way.

    Cool.
    Sold mine about 05 06 I think, so not the same one. Rejuvenated a D4 after that went, it had been sitting out in the rain for 13 yrs with nothing covering the exhaust so I had to smash the pistons out with a big hammer and resleeve it. But got it running fine and used it for a year before moving it on and getting a TD6 and Td9 to play with.

    That'll be good to see, I've never seen the internals of one of those. I was thinking that they couldn't all have disappeared and there must be quite a few scattered around the country, at least we now know where 5 of them are!

    I have read that a TS3 engine was used in England in the development of a super economical engine - not sure of the results but I do have the article on it somewhere and I'll try and dig it up later.

    The Norton Kneeler

    http://www.motorcycle-usa.com/289/16...n-Kneeler.aspx

    Although this is an American site, they seem to have the best info on this machine. It had a relatively conventional Norton 350 Manx engine, yet managed 146mph in 1953!
    I can actually remember it's first race at the NW200 - Went like the clappers but ended up parked up someone's driveway half way round the circuit, after it overheated and stopped on the second lap!

    We called it the "Eggshell Norton", aptly named maybe but everyone was waiting to see it. It did have some real potential, or at least would have had if they had been allowed clutch starts in those days! - can you imagine trying to bump start that thing off the grid, then trying to clamber aboard!

    Heres a MODERN oddball motorcycle

    A 1400cc parallel twin 4 conrod twin counter-rotating cranksaft turbo diesel motorbike made by Neander motors

    www.youtube.com/watch?v=gL0QyScysQk

    One write up i read said it works well if somewhat noisy typical of a diesel motor
    It can run on just about any light oil like the diesel motor was originally designed to do.

    Maybe it'll get nowhere in this form but the principle is very interesting just the same!

    For someone to get it to this stage they wouldn't have been smoking at all, ie judging by the state of some of the apprentices I (tried) to instruct - they were smoking, but in their state, they certainly could not have thought up anything like that, useful or not! - all they could ever do was wreck machinery!

    Quite surprised this one hasn't come up yet!
    The Duke engine is well into it's development now and this has been happening right on my doorstep here in Auckland just a few miles (Kms ?) from where I live.

    It seems to be a modern development of the 'axial piston wobble plate' engine used by Bristol Tramways between the wars and with modern metallurgy, it should meet with a lot more success.

    It is now well advanced and working quite well it seems and I hope that they can break into the automotive or aircraft market (a daunting task).
