    here is my photo bucket thumb

    please click
    then click next to get 2 more shots


    i'm thinking of mounting a 49cc motor on that solid rear frame in back
    and shim it to maintain chain tension
    the rack measures 4 3/4 " center of tube to center of tube
    rack tube diam. 1/2 "
    rack length aprox. 16 "
    min rack to seat clearance 10 "

    i want to run the chain inside the rack using Staton's rear 36 Hole 12 gage Hub (w/ left and right hand threads).
    i'd like to use a bump start /centrifugal clutch, kill switch and governor

    is this possible?

    how about a 2 stroke with a comet CVT? any recomedations?
    how big of a left sprocket?
    i don't know if i have this logiced out right...
    i hook a kill switch to the brake and when it's aplyed the motor kills and i slow down. i let off the brake, the motor bump starts, and i resume speed.
    i was thinking of two throttle settings one for dirt roads and town and one for hardtop...

    Hi and welcome, If you go with a 2 stroke realize that most of the ones used on bicycles have a shaft smaller than the 3/4" usually required for a comet CVT. You will likely need an adaptor or shims to fit the driver on the output shaft plus the CVT back plate uses a bolt pattern designed for the 4 stroke engines. You can fine small scooter CVTs that will bolt to most engines with the 76mm clutch. These reverse rotation and drive on the right.
    The kill switch on the brake would be a nightmare, at slow speeds it would be too much drag,doesn't sound like a fun way to ride at all. Keep us posted on what you do. This place is full of new ideas and experimentation.

    Oh, I forgot to mention, Comet went out of buisness. You can still find comet CVTs but they are pricey now. The american made copies are good. The china made copies are said to be of lower quality. Go figure.
