    https://1drv.ms/a/s!AinqmFaefNIciRuiMDt8JORZyUk6 Not ever having a Facebook account I didn't know about any other mini bike site than this one, that was created for and focuses on vintage builds; not so much on custom or muscle builds. Here is one that does...

    newly built motor fail, need advice

    Every thing scrutinized again and again and cranking again and again til my shoulder is sore. The plug fires outside the cylinder, then after cranking for a while starts to get wet. It feels like it has the 11-1 compression it should have, and tried at 34* and 28* timing. The cam-crank dots are...

    taking exhaust outside the box

    I would like my new motor to be muffled a good deal. Even if it loses some power. This is the top of a stock GX200 muffler and I wonder about the circle shaped structure there. Would that be a good place for a second outlet? Has anyone drilled a stock muffler full of holes and it still sound...

    Here I am in the land of giants

    I would like to build a dragster, rear-engined , with the motor and operator on the same plane, the operator directly in front of the motor, not above it. Think Top Fuel dragster but shorter... This will never happen, but I can dream large; would the group settle for a stretched doodlebug? Or...

    cam lobes

    This is an Isky 260/220/104 with many many hours on it. Will someone tell us what the heck is going on with both lobes losing their integrity? Is it repairable or has it lived out its life?

    timing and acceleration

    I just read this on another thread: " My advise is install a 4 degree offset key to back your ignition timing from the built-in 32 your billet flywheel has that was engineered to run @ a continuous high rpm in narrow power bands on racing engines to a more acceleration friendly 28 degrees...

    NSFW: lewd, obscene images

    The Outlaw Minibike Scene Of Detroit, Michigan - Roadkill Says one guy has 27 minis...I'm afraid if I started on another one besides my beloved Hillbilly Deluxe it would cause hurt feelings and she would become hard to start and maybe develop slow leaks in the tires. Also, all I want...
