    Hi, thought I would share with you the test rig I set up to test an engine out I recently built up.
    Just used an old road bike frame & found I could start the engine by just manually turning the rear wheel with the clutch already engaged so I did not need chainwheel/chain or clutch lever/cable which I have since removed.
    Thought it would also be a good way to run in new engines without having to go out on the roads at low speeds.

    That's pretty neat. what kind of repair stand is that? I've been lookin for a good one that'll hold the weight of a MB lol.

    Anyone done something like this as a dyno?
    Loading up the back wheel with a fan or generator or inertial weight and some sort of sensors to record RPM vs time would give a comparable HP curve.

    Stand is just a regular bicycle repair stand that I use to repair my push bikes.
    Weight ain't an issue as there is only the frame,rear wheel,gas tank with small amount of gas,engine & exhaust.
    Reason I did it was to enable me to see if a repaired engine was a runner b4 I spent valuble time in fitting it to my proper bike only to find more problems!
