Here's why I'm confused: when you say "run the chain forward" are you talking about driving the front wheel? If so, won't steering become a problem? The other issue is this: when the engine's drive sprocket is on the left, it and the rear wheel turn counter-clockwise. If you mount the engine backwards with the drive sprocket on the right, no matter which wheel you power - it will still turn counter-clockwise, meaning that on the right side of the bike you would indeed go backwards, i.e. in reverse. Unless you rebuilt and modified the engine to compensate.
Might I suggest a jackshaft to accomplish something similar.
