    2-valve 750 dyno?

    Has anyone done it? I'm mostly just curious, more about the torque curve than the peak numbers. I've seen some 1000 2-valve graphs and an 1150 that have a fairly flat torque curve, is the 750 the same way?

    The advertised peak numbers seem all over the place depending on where you look. Maybe 70 hp?

    I've done it on my GS750. Any performance gain was secondary to me wanting something more reliable to the original points. To be honest, any performance gain I may have noticed would have been due to my inability to precisely adjust the old points...

      You don't still have the results do you? Or remember how flat the torque curve was?

      I think I might be the only one that doesn't mind the points. I've checked mine the past 3 oil changes and the timing hasn't moved at all.

        I found this from Cycleworld. Rear wheel HP and dyno model is listed so it looks like it was their own test.

          He's asking about power and torque output, not converting to Dyna setup.
