    I was really surprised how my 660 ran the 11 pin sprocket on a cut down 36 inch bar to 32.5 inches and full comp chain. I really thought it would pull the saw down but the sprockets mass holds rpms well.

    Ok if the sprockets mass isnt acting like a larger flywheel then I really appreciate the confidence boost on the raw horsepower ability of the saw .

    11 pin full comp. Next you will probably cut the rakers down to .040. How about an 18 pin with skip chain? Try running at dark to see all the sparks! If you can run an 11 pin and not bog the saw, then you do not have a sharp chain.

    When viewing your YouTube video, click share under the video. Click copy link, then when you get back here, paste the link. Easy as that.

    I'm also wondering if the math on this site for figuring chain speed is correct. I'm very familiar with formulas for figuring speed and adjusting variable pulleys for a specific speed all those formulas take the diameter of the driven and driver pulley into consideration . The closer the driver diameter is to the driven the closer the driven rpms is to the motor rpms . A 2 3/8 inch driver diameter sprocket should be close to the bar nose diameter, haven't measured nose but will . Actual Chain speed was measured with a fluke 820-2 stroboscope. Stay tuned and your welcome to join the Facebook group kisin piston chainsaws. Thanks ,Mitch

    11 pin, 3/8.
    15,000 RPM is 10,312.5 FPM
    687.5 ft per 1,000 rpm
    68.75 ft per 100 rpm
    Your saw would be tuned just over
    15,500
    Over 120 MPH

    That's damn fast....raker height & inner top plate angle would need fine tuning. I'd be wearing decent PPE, 'chain shot' could be a micro second you remember for ever.

    It's much more dangerous than the stock setup, but it cuts way worse.


    Wait, hold on a minute...

    So you're saying it's the worst of both worlds?

    11-pin sprocket ... reminds me of Spinal Tap ... "Our amplifiers go to eleven. For when you need that extra, extra, extra push over the cliff."

    I want a 22-pin spROCKET.

    Yup.
    Double the speed is four times the energy.
