    Correct wheel bearings for minis

    Flanged bearings are for low speed use. Snap ringed bearings are generally high speed precision bearings. With that said the quality of any bearing is the buyers responsibility.

    If your chain has a loose or tight spot or is bent, it is time to replace your chain. Rupp did offer a chain tensioner for the Bandit, so you are already on the right track with your added tensioner.

    Mystery ‘68 Rupp Build

    It would not have a two speed as I now see it has the 60 tooth sprocket. It would be a XL-500 or XL-350. They use a jackshaft with 2 sprockets on it. Here is a link to the 1968 Rupp parts catalog: http://blackwidowmotorsports.net/1968_rupp_minibike_part___catalog.html

    Mystery ‘68 Rupp Build

    It's either a TT-500, XL-500 or XL-350. Since it does not have the original engine there is no way to tell.
