    And defiantly don't do that. He was an Aussie cocksucker.

    But they never wen away. Been out on my dirt bike today. Nothing like a 2 stroke coming on pipe exiting a corner Wheeling and sliding the rear at the same time making that beautiful noise and producing more torque than a poxy 4 stroke.
    Don't you look at my accountant.
    He's the only one I've got.

    Ryger finally bought a dyno a couple of weeks ago.
    Where those supposed 70HP came from? They were just calculated.....
    The new dyno seems to be a real bad one.
    As it shows far less HP than expected.........
    New explanations will follow: have patience! as always!
    The 50cc version seems to give 14HP I heard.
    The world record attempt will have to be postponed a little.....

    The problem with calculators is if you add bullshit numbers in you will always end up with bullshit results.

    Yes they are making huge inroads on the 2 stroke engine,

    Just looking at the new Evinrude G2 150-300hp engines I know its a boat motor but!!!

    The E-TEC G2 delivers up to 30% more torque and burns up to 15% less fuel than competitive outboards. Delivering best-in-class torque, best-in-class fuel efficiency and the lowest total emissions.

    The E-TEC G2 engines are cleaner than competitive four-strokes.
    100% Global Compliant, so no matter where in the world your
    boating takes you, the Evinrude E-TEC G2 is welcome.

    I think the issue with bikes (especially dirt bike 2 smokers) is weight and generating enough power/pressure to run the injectors etc with direct injection?
    They dont have that issue with boats extra few Kg no issue, on a dirt bike big Issue.
    The other manufacturers might not. But pretty sure KTM would do it if they could, they still have a 2 stroke heart.
    The rest just wanted to go four stroke because everyone in the food chain from manufacturer to Mechanics make a shit load more money out of four stroke sales, parts and engine/valve reconditioning.
    This pollution thing is a crock of shit! You could start all the 2smokers in the world up and make fuck all difference to the pollution, its about money.
    On a Motorcycle you're penetrating distance, right along with the machine!! In a car you're just a spectator, the windshields like a TV!!

    I totally know what you mean, dropping the Vespa PX 200 into 3rd going up Parnell Rise...
    DeMyer's Laws - an argument that consists primarily of rambling quotes isn't worth bothering with.

    Awesome clips, brings back some memories, was a flag marshal at the Wanganui meeting, I remember Don Cosford working his RRRrss off with running that.

    Something special about those sounds, always remember as a young fella chucking castor oil into my 2 smokes for the smell affect.

    According to what i have read a lot of the problems with these were down to leaking crankcase castings as wel;l as a poor fuel map.

    89 Lawson, Rainey, Schwantz, Doohan, Spencer. Sarron, Chilli, Magee, Mamola, Gardner must have been injured?

    That's an mbx50. Some of those sound pretty dreadful. Especially the scrooters. But the old race bikes sound great.

    1.33 MBX wheels but it sure looked like a MB5 frame.
    I never watched it all.
    One of the first ones looked like it had a 4t MGP look a like scilencer on it.
