Re: pictures of multiple engine bikes i saw
Since i was the only person from this board so far to see the bikes and talk to the owner , I thought I should I should chine in.
My understanding was that all the motors were direct drive to a jackshaft with one lockable hub. That hub has a sprocket which drives the rear wheel. When the hub was engaged , while being towed at about 25 mph, all motors(hopefully) fired up and have one throttle that controls all the carburetors. There are no clutches needed.
I hope that clears up some confusion
