    So my bike eventually started! I have ridden a lot on it! It had some problems so I had to re mount and must have lost the bucking bar. Does anyone know how to make a new one?
    I have a 80 cc motor bike
    I live in Athens/watkinsville Georgia

    Am 15 with a learners permit
    I enjoy making stuff like this
    can I legally drive around? (have been doing)
    Thanks!

    .duh.

    Not sure what a bucking bar is. Google says it's the block you put behind a rivet to set it.

    And most places require you to have a license of some sort, so check your laws. An easy internet search will tell you all you need to know. Also, make sure your ride is legal. SC law here says I have to have working brake lights when either brake light is depressed, a head light, tail light, and functional turn signals. Also have to have a rear view mirror, can't go over 25 mph, no more than 2 horses, and can't physically make the moped go over 30 on a flat surface.

    The bucking bar length is critical. That's the problem with making a new one without your original for comparison.
    As for making one; if you have a way to cut it, a 5/16" or an 8mm drill bit works well. The ends need to be slightly rounded and smooth. You can use softer steel but it will wear faster. The shank of a drill bit is best but you could also use a hardened bolt, grade 8 works well too.

    I don't have an exact length to offer you right now but something close to an inch and a quarter will get you in the ball park.
    If you lost the bucking bar you might have also lost the ball bearing that goes in before it. It too is 5/16" or 8mm. Both parts and the cam in the clutch actuator cover need to be lubricated with a good grade of bearing grease prior to reassembly.

    The bucking bars on my motors are 1.046" long.
    I also carry a longer bar that is 1.103" long.

    I wouldn't have thought 1" would have done it but we're sure glad you have it fixed.
    Have fun and ride safe.

    To post pictures from your phone you need to download a photo editor app, resized pictures to 1024x768 pixels will upload from my phone. After resizing the photo save it to your pictures.
