    Crude 1 night bike

    Did not go as planned and just rolled with it. Nothing is square or even. It's got character. Evan williams and impatience led the way. The hazard fraught pipe folder did exactly that. Long as the forks, motor, and rear wheel's straight, she'll be right. Needed something tall enough for a...

    A slippery subject , oil weight

    Oil brands and synthetic vs conventional oils have plenty of opinions associated with them. I get it, and that's not the direct focus here. Typically 30 weight oils are what's dumped in predators and the likes, as I have done for years. Stock or hopped up, 30w seems to be the "norm" I see...

    190cc Honda swapped 125 Pit bike Manual

    Totally not clickbait. Dumb idea, use blade stop clutch from a honda hrx217 hxa style push mower as a cheap 3d motorsport style manual clutch :P And preform mad wheelies and peels??? Took a junk gcv190 OHC vertical shaft with a bent crank, and swapped the crank from a motor that pushed a...
