The metal cylinder might be a pin that is intended to hold a shift fork or shifting cam in position so the bike will shift into first gear?

  That would be my bet....  the roller bearing or pin in the shift cam.

1. Can someone please explain in plain English what you think the likely proper function of this retaining pin is? Is it as Arizoni said yesterday?

The shifting mechanism has a disc attached on top of a rotating slotted cam that moves the shifting forks back and forth that engage the gears together. The disc has four pins like the one you have in your hand.  There is a Wide U-shaped hook that is attached to a bar that is pulled back and forth by the shifting levers engaged by the shift lever. As the U shaped hook goes back and forth, it pulls or pushes the appropriate pin to rotate the disk and cam which moves the forks.

I see what you mean Bare. I will amend my guess to one of the shift pins, i think you nailed it.

If I was going to guess, the discovered pin is the "First Gear Pin". :)

If it fell out, all the lever moving in the world wouldn't put the transmission in first gear.

Also, if our guesses are correct, riding the motorcycle long distances would be totally safe as long as first gear wasn't really needed.

@Rich:

You may want to call CMW to see if they have the parts in stock.

Part Number for the roller (#25 in picture below) = 550075

If the ratchet plate (23) is bad, then whole cam plate will need to be replaced.

Part Number for the gear shifting Cam Plate Assembly (22 and 23 in picture) = 570216.

The crankcase will have to be split open to do the job.

Rich,
If for no other reason, getting the warranty service on this will also determine whether the other pins are loose. If one already ended up in your sump, the odds are good you may find another next time. No point in letting it go for too long.
Rather than have a homeless person for the holidays, I decided to stick with ham.

Don't you worry. I'll definitely have a dealer look at it as soon as practical... I'm adventurous and incrementally more risk-tolerant than some people, but not crazy!

Happy to report I've just gone 185 mi in 3.5 hrs (NYC to White Marsh, Maryland via turnpike with no problems. Bike is running beautifully on the new oil. And if I'm not mistaken, I've seen a small improvement in MPG. Is that possible?

As the bike breaks in, it will usually get better mileage. As the parts are fitting together properly the internal drag goes down.
