    As some of you know, I am the new owner of a 1987 TW. I replaced the CDI, got a battery, got another carb, and voila! It ran! Noisy thing. One sound was like marbles rolling around, so I searched and learned others made the same remark. The answers to the noise ranged from, "buy earplugs," to"that's the way they are." After riding around the woods for a while, I stalled it, and tried to crank it. It wouldn't crank. I tried the kickstart, and it wouldn't move. "Frozen," thought I. I opened up one side today to discover:





    Apparently one screw had fallen out, and was rolling around, followed by one side of the stator, after being ripped out of its place. I have one broken screw, and a plastic part around one magnet loose, but the motor now is free.



    What are your suggestions?



    Thanks!

    Wow. That redefines "ugly". The really hard part might be getting rid of all the shrapnel.



    Might be able to help. Check your mail.



    I can explain it to you, but I can't understand it for you.

    Powdercoated '87 frame, extended swingarm, YZ fork legs, ATV tire, 14/55, XT350 tank, spliced quick-release seat, disc brake conversion, beeg headlight, beeger rack, Lizrdcooler, Lizrdventz and bunch of other stuff all covered in invisible ink.

    The fun part was trying not to get the tweezers drawn to the magnets! At least the stator assembly is shared by a number of years, and not specific to the '87. MY

    Slightly off topic and I don't mean to critise but this illustrates perfectly how difficult it is to diagnose engine noises on the internet.

    Some people think all engines should sound like a Swiss watch while others think imminent destruction is normal.

    Anyway I hope you can fix it soon.

    Imminent destruction isn't normal?



    I must be riding too slow.

    I've used Grade 8 bolts and Loctite the last couple of times since the Philips just looked puny.

    You are convincing.
