    yz400f clutch arm mod

    I just bought a 1999 yz400 in very good shape and remember seeing a mod in one of the magazines for lengthening the clutch arm on the engine for an easier pull, any body remember that -Thanks

    Thanks for the info, I think I know what your saying. I tried to get the pictures but it wouldnt let me. I hope the yz400 has the same lever and perch as your 426's

    The only drawback to the lever mod is that you fall a lot, or at least I do, and tend to break them. I have access to a machine shop so I can modify levers whenever I want. If you do the clutch arm mod, you are done with it and don't have to worry about it.

    cranky. I have a 98 YZ400F I just bought and I have the magazine that gave a step by step on how to do the extention to the clutch arm on the engine. The mag said to only extend the arm 5mm's. This easy to do trick made a BIG difference and I also use a CR clutch perch. If you want I will try to find the mag. I can scan it and email it to you. email me if you want. crboy@nightowl.net
