It was AWESOME!

Once I had front friction drive and rear chain drive with different gearing.

Same engine, and they both had the same expansion pipe.

If both engines were idling, I'd sometimes start off on one engine. When I got to 15mph, I'd release the throttle on the running engine on the front wheel, then floor the idling engine on the rear engine!

It sounded EXACTLY like a single engine with a 2-speed transmission!
That was neat, but NOTHING beats the drone of twin engines. You hear the same drone on twin-engine commercial airplanes.
I don't know about twin engines so much but I do know my roomies twin cylinder Harley sure has a "drone" when he idles against the house to warm it up....

It's like when a bunch of souped-up mopeds pass by a hundred yards or more away.
