    Hey guys,

    I aquired a mystery bike. Need help identifying it because it'll need new parts. Compression seems low. It runs for a few cycles then shuts off. Can't seem to get it to run consistebtly and I been screwing with the carb screws. Kick start is pretty easy to kick over also.

    The engine says 86ml. I suspect is a Chinese brand bike, check out the pics.

    "Engine Number" is 03053258 as stamped on the frame.

    Thanks!

    Definitely Chinese. If you need a new piston/rings most chinese 86/90cc motors use a 47mm piston (same as a stock stroke 70/72cc). The engine number on the bottom of the motor on the chain side below the sprocket will confirm this if it has a 47 in the first 4 or 5 numbers (eg IP47########).

    Will be difficult to tune the carb while there is no air filter on it, it would be very lean ATM. Bang a lightly oiled unifilter on it, and check valve lash before you go looking at the piston and rings.

    Thats the plan...
    It was in rough shape, but it turns over fine.
    My plan is to do the following:
    Valve adjustment
    Timing
    Spark plug gap
    Oil change
    and overhaul the carb

    I hope itll start after all this!

    I'm using a Honda CT90 Manual for reference. I'm not sure how similar it will be just yet.
    unfortunately, I don't really have a compression measurement tool. I'm not keen on buying one since Ill probably never use it again.

    Check your valves. The ones on my bike got tight you could kick it by hand. and wouldn't idle/ run on the bottom end.
