Re: Twin Engine Rack Mount
Twin engine gokarts were common years ago. You just had to get them running close to the same RPM at any given throttle setting. We used two cables to one gas pedal.
If the engines are identical getting them to sync isn't that difficult.
The problem I see is mounting. One engine will need to be mounted way off center to get chain/sprocket alignment. On a gokart it was not hard. One engine drove a wheel the other the live axle. On a bike you don't have the width to play with resulting in problems with sprocket alignment. Some guys modified the engine to run in reverse to drive both rear wheels.
Removing the pedals in most states will make your bike a motorcycle in the eyes of the law. You might want to explore that before you get too far into your project.
