    I have a ~67cc China girl from boygofast with about 1000 miles on. I did a tear down because I knew at least one bearing was bad, turns out both are bad. I'm also doing some port work while I have it apart.
    I measured the inside and outside diameters, and they look to be about 15mm and 35mm. I really don't know much about bearings and which type would last at least 3000 miles.

    I don't see on their website where they sell parts. This site is selling them for $15 a piece plus shipping, too much for China parts.

    I think you're right misteright. I thought it meant 2 are required but this is only one item.

    I just bought 3 of these 15x35x11mm ball bearings on ebay. I had to heat the case to drive the old ones out.
    Thanks for your help. Half the fun of a motorbike is working on it.

    The bearings you bought on Ebay looked sealed. Are they stock bearing sealed?

    Yes they were sealed but I was still able to grease the old bearings by forcing grease into the hole that the clutch cable holder screws into.
