baird4444,
Thanks for the link to "tinytach".  I guess REs have one spark for each revolution(wasted spark on the exhaust stroke).  Right?
Thanks,  Jim

I think that is correct but don't quote me. I never bothered remembering that one cause I didn't plan on ever getting the tach.

   I'm going to bet that the Bullet does not spark on every stroke. Why? Because if they did,then when you used the method of parking the bike with the piston at TDC on compression stroke, said method wouldn't work.You apply the compression release, and turn key on.Ease the kick start over till you see the ampmeter needle go to the far left, then a bit more till it comes back to the right. If this thing fired a spark on every revolution, then this method would not find TDC on compression stroke--but just TDC period.
    Someone smarter then me tell me if I'm right or wrong please.

The ratio of crank to  cams and distributor is 2:1.  Dist turns half engine speed.

I have an xls spreadsheet calulator for this. With a 17t sprocket, I get 4200 rpm for 65mph, 3800 for 60.

dead on, balls accurate?

That's Marisa Tomei's line in My Cousin Vinny. She's the daughter of a mechanic who clinches the mystery of an armed robbery at the end of a lost-cause trial.

Ah, my friend, I got the reference. I was hoping you would give me the follow up: "It's an industry term."

Alas, my own memory of the sketch was not up to par!
