    3 times the strokes, 1/3 of the power? doesnt seem that clever to me lol

    instead of 1 power stroke every 4 strokes theres 2 power strokes every 6 strokes, so surely theres more power

    and how is 6 strokes 3 times more strokes than 4 lol

    Check out

    www.sixstroke.com

    This guys been trying to get his invention off the ground for 20 years. He even pitched it to Ducati a while back but they stuck with their own valve technology.

    He's built a six stroke Ducati and had an ex Aussie ducati racer test it back to back with his own bike and while the rider felt he wasnt any faster, his lap times were apparently better.

    I saw this guy in Australia about 7 years ago and this thread reminded me about his work so I did a search and found his website. Seems as though he's still having trouble selling it to the big boys even though its a solid proven technology.

    Hope its of some interest.

    The article talks about doing away with the heavy radiator and cooling system, but as the volume of water injected is greater than the volume of fuel used for a combustion cycle it'll have to carry a (bigger) water tank as well as a fuel tank.

    Apreciative Guest

    Greetings from Melbourne Australia guys,

    Firstly, congratulations on a great Forum.

    Thank you Christos for your www.sixstroke.com mention.

    Your observations about Malcolm Beare's Six Stroke Cylinder Head are almost correct, the truth about this amazing invention having disapeared from circulation during the past 5 years can be found in http://www.sixstroke.com/truth.htm, the good news is however, that despite the legal challenges currently being dealt with, and regardless of the great lengths which some unscrupulous parties are stooping to in an attempt to stop Malcolm Beare from further advancing this incredible ICE breakthrough, Malcolm and his new support team are making huge leaps in progressive development of his invention.

    Some revolutionary lessons are being taught by this device, and some perplexing questions are emerging as a result of the unique function of this concept.
    Here are some interesting discoveries/questions: 1) during the full load stress of the latest Burnout filmed earlier this year, our AFR meters registered between 17-18 to one parts of air to each part of standard pump fuel? 2) the digital temperature probe pointed at the exaust dump pipe immediately exiting the cylinder head during the burnout, measured some 70 degrees cooler than the factory Yamaha 500 poppet valved bike under light load, being used for comparison? 3) the additional torque generated by the new Beare Head six stroke cylinder head tested totally eclipsed all previous power tests, the shear torque punishment this version was exerting upon the drive train during the slow rpm (750rpm) burnout under tire melting load, caused both the gearbox and clutch to spit the dummy.
    ( very rear for the normaly bulletproof Yamaha XT/TT 500)

    Stay tuned for more progressive updates about Malcolm Beare and his amazing Aussie invention.

    Let us all join hands in saluting the humble inventors of this world, lord knows that without them we would all be still riding donkeys.

    Thanks again guys,

    Steve

    and in my experience cast parts tend to disagree with suddenly being cooled and contracting. Seems like a poinless exercise to take it any further than the bench design he's already got. It will slowly destroy the rings, valves, water will end up in the lubricating oil. Flawed to say the least

    thanks for that

    I'll keep an eye on his progress. I've wondered about the Beare cylinder head a few times in the past year or so (usually whilst fixing the head on my Husaberg 650 thumper) but it was only when I read this thread that I thought to investigate again.

    I saw Malcome as a guest speaker a few years back at a small monthly gathering of innovative thinkers group in South Australia. He came across as a genuinely good guy and I really hoped he would succeed after hearing his story and seeing his efforts. All the best to him.

    where is the advantage here?

    So far :

    replaced a radiator with a water tank

    added moving parts

    cooled exhaust temperature (why are people heat wrapping if cool is better?)

    wetting the plug (something I'm struggling to get a grip on)

    Combined a two and four to make a six stroke, what element of the 2 stroke has been incorperated?

    surely increased the likely hood of seizure?

    enlighten me

    thats exactly what i was about to say, the life of the engine would be really short and reliability shit.The firs thing i thought when i read it was, what will happen to the spark plug, the oil will mix with the water and what will happen to a hot piston when you spray water on it...from physics a material changes its size when cold and hot, so what happens to it when you constantly heating and cooling it. it does not make sence.

    the first one was a diesle, so no sparky. i cant see why it could not work, wont be the best performance engine ever but it will cut the fuel consumption down.
