    I have a problem any feedback will help ok I installed this 80cc motor on my mountain bike. Witch has no paint on it ok.. ran fine I decided that I wanted to put it on a cruzer .i did just that it has paint .ok so I sanded a spot and grounded it to the frame since the other frame had no paint an was grounded .the motor will not start ..and all I did was switch frames and added old inter tube for vibration to dampen it ... I took the ground off still nothing grounded it back won't start .it's got spark it's getting fuel has good compression. .and ll I did was switch the frames what would keep the engine from running I can't figure it out so any feed back will help .thank you .

    Do you have a ohm meter to check for ground? What type of metal was the old bike? What type new Bike? check both at the same place, may just be a difference in material. Should show continuity. The meter that Harbor Freight is good and cheap. Hope this helps.

    I have an 80cc 2 stoke motor on a mountain bike, its great just going to relocate the gas tank as while peddling to get the motor going led to my inner knee to get bruised from hitting the gas tank, but definitely fun. thinking about adding another tire at the back for more traction

    Can you help me build a motor bike

    Two cycle engines are PIGS! They pollute in one hour what a full sized car does in one *year*. There are lots of hustlers on craigslist who take an old bike, throw this cheap cina-made 90 dollar 2 stroke engine on and try to re-sell for 500. bucks to some moron. If you want to power a zero-polluting bike, at least use a battery driven motor. This is their heyday - tons of choices - and no jerky oil-gas to mix.

    sadly, battery technology doesn't provide the longevity of the internal combustion engine, but has much higher torque, with weight being the downside. Why not use a 4-stroke engine?

    So, there are no instructions?
    We need instructions to do this.
    It looks great, though.

    If no large motor is nearby and you are not handy with tools a model aircraft engine of 1.5cc preferably greater cc. coupled with a fixed skate board wheel bearing directly down on the back tire will move you along at a surprising pace.

    ya i have head of many people doing that (chainsaw) using a friction drive or a belt drive, a chain drive would probably work also, but you would want to make sure the gearing is just right because chain saws have high rpm's. you might want to check out some cable throttles that have a twist grip, if you look on motorized bike websites, you can buy just the throttle assembly which with a little modifying could work pretty well.
