I'm looking into this, you'll have to change the sprocket as most aren't designed on the same pitch as a bike chain, you'll want to leave the centripetal clutch intact as it will allow you to idle at stops etc... It would be best to use a multiple speed bike to allow for some leeway in sprocket sizing and torque conversion. The part where I'm stumped is determining what engine size will give me the best speed and climbing ability with my weight and allow the engine to operate in it's power band. Other wise it's going to require some welding skills as the tubular frames of bike are typically very thin. My idea is to build an adjustable cradle around the engine and weld the cradle to the bike and use a bike that has at least two speed changing sprockets in the front, this way I can leave the rear dérailleur system intact, and use the second sprocket in the front to run my power chain to. You can purchase extra brake cables at most big box stores, and bike shops, with a little ingenuity you can hook this to the handle bars to control the throttle with, the other controls should be located directly on the engine, IE choke engine stop and primer.
Input from ChetsJug: Besides the fact that there are several forums that cover conversions, I went into a local bike shop today and asked them if they knew anything about this. The guy had helped a few other locals and knew the sprockets to use and some tips on mounting platforms. Try finding a local bike shop that can help you not have to "reinvent the wheel".
Hard to tell. Sometimes a bigger motor run on a smaller throttle will use less fuel than a smaller motor run all out.
It all depends on the motor and battery that you use
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
all the electrical machines can be run either as a motor or as a generator. but dc machines, A motor can be run as generator and vice versa with little modification
The motor simply wont get enough fuel to run properly.
Why get rid of the excellent BMW shaft drive and use a chain? You should sell this classic bike (even if it doesn't run) and get a bike with the engine removed (called a "rolling chassis") at a junkyard. The price of that BMW will likely finance your project.
If a motor is designed to run on different voltages there will be a wiring diagram on motor plate for 120 volt wiring. If not you will have to use a step up transformer to convert 120 V to the higher voltage.
One would assume the chainsaw requires 120 volts or more if you want to run it with an inverter. If your chainsaw uses 16 amps at 120 volts then your wattage is Volts (120) x Amps (16) and that would be 1920 watts. So you will require a much larger inverter to run your chainsaw.
start the bike let it run for a few minutes kill the bike there is a dipstick in the oil tank that's attached to the frame in front of the motor
No. More people run on the bike path by my house then ride their bike on it.
if you have a 4stroke dirt bike you run straight gas ,if you have a 2stroke dirt bike you run mixed gas
