  1. engine problems

    General Pocketbike Discussion
    So i bought a bike for $65, so far it's had many problems, they include: it leaks petrol out of the carb, for some reason black liquid gets into the clutch area, a lot of vibration, enough to unscrew the spark plug. Also when you go WOT the engine cuts and this is the same when you give it none...
  2. Replacing an Air Cooled Motor ?

    Air Cooled Pocketbikes
    I have a Chinese copy/replica of the Origami B1 which is air cooled and not Water cooled. I'm wondering if it's possible to take out the Air cooled motor and put in a Water cooled one. Would I be able to do that, or would I have to buy a certain frame or anything, or just a new bike total ?
