THE COMMANDO ISOLASTIC ENGINE MOUNTS: Dr Bauer designed a frame with engine mounts carrying rubber bumpers to isolate the rider from the vibrations of the large parallel twin Atlas engine. The unique thing about the bike and frame, was that the swinging arm was connected directly to the engine plates, and therefore the engine unit. While this arrangements gets round the problem of transmission snatch and windup from the rubber mounted engine with chain drive, it also creates its own problem, a 'rubber' mounted rear wheel. (That is, the rear wheel is rubber mounted through the rubber engine mounts to the frame).

Hmmm, sounds like you would need to replace with urethane or polybronze

They have good kits to either remove or detune the 'lastic part
of the isolastic.

If you get an old Norton - I hear the 850's are the way to go.

Norton cases were sand castings, I think, and could be porous. So the
engines are usually kind of grimy from the seepage. But nonetheless
very cool bikes!

WOW, an old roommate in college used to ride a 550 just like that. Had to teach the dork why he shouldn't have cross threaded the plugs. He wrecked on several occasions (small brain, no fear). The funniest when he drove off to a halloween party w/ a cape. We *TOLD* him it was a terrible idea. He apparently made it ~1mi before the cape wound up in the chain/wheel. Lucky it didn't yank his dumb ass off.

Good times, Takes me back.
