I won't make mention of my friend (dave) who wanted so desperately to do this same thing that he stripped apart out his entire '77 cb750k, sold the engine, and aside from a few bits he gave to me for free, has now sitting in/outside his folks garage. Poor bike. I do love dave, he's a great friend.
But, just to play devils advocate (and according to some on this board), that monstr-electr-osity is no worse than what some of us are doing to our bikes (eh ehm...me perhaps, just to name a a name?
).
...but at least mine will still burn oil
