    Real nice job on the modification. Would you be able to tell me what the ratio's of your current clutch lever are? I'd like to know distance between the pivot and the cable barrel, and also distance between the pivot and right around where your ring finger would be on the lever. Curious to know how close your ratios are to the EZ pull lever we sell.

    Sure. Lever pivot to cable barrel around 1.065, pivot to ring finger 3.753 or so and clutch center to cable stop barrel approx. 2.835.

    Thanks for the info. Here is the specs for our EZ pull lever:

    Distance between pivot and ring finger: 5"
    Distance between pivot and cable barrel: 3/4"

    The EZ pull lever gives about 6.6:1 ratio between movement of the lever and rotation of the actuator.

    Your setup without the extension provided a 3.5:1 ratio. With the extension, you're at 7.7:1.

    I'm sure that given your low power output, the 7.7:1 ratio is a huge advantage.

    I just received my new levers from 3D Motorsports. Quality is tops. One has a locking button for the clutch and I'm using the regular one for more leverage on my front brake, plus they match. I'm going to try to install a spring on the lock out lever to return it to unlocked position so it will snap back on it's own instead of having to push it the opposite way to release.

    I modified my new lockout clutch lever with a return spring and will be installing it soon.

    Here's my new lever. Much better fit and improved spring return.
