2 Engines Twice the Vibration?

I'm thinking of mounting two engines on one bike. They will both be automatic clutch engines of the same type. I was wondering if the lack of linkage between the two engines will cause them to run in and out of ocolation with eachother poably amplifying vibrations?
 
That is entirely possible. You'll just have to use two throttles, and sync them up like a twin engine plane.
 
One of the cable splitters (1 cable goes in, 2 come out) used on 2 strokes with an oil pump will have them opening and shutting together. It's just a matter then of small adjustments of them to work absolutely together.
 
Recently I saw a show where a guy had 2 V8's in a hot rod, he said his biggest problem was syncing the engines which is extremely important because one engine can/will destroy the other. Now then,,if this would apply to 2 two cycle engines I don't know. he ended hooking up the engines together and were phased to fire opposite of each other.

FWIW Honda used a twin cable throttle control that was controlled by a single cable.
 
its easier for a car because if you start with marine engines because they come in both rotations you can make then counter rotate with each other
 
Well that's true but they have separate drives and are independent of each other.

I do wonder however that if the bike engines were hooked together 180 deg's to each other if vibrations would be canceled out.
