Lost Washer PV to Clutch Side
 

I found that my washer and allen bolt that holds the PV lever on the shaft had backed out. I found the bolt back at the scorpion on gear shift shaft. I haven't found the washer. I haven't pulled the side cover yet but I looked with a mirror with no joy. I'm afraid its gotten deeper.
If I don't find it when I pull the side cover, any other ideas? any bets where I will find it? If I don't find it, ride and pray it stays on the bottom
of the gear case or split the engine?

Do not ride the bike.
You can have catastrophic transmission failure if the wash gets jammed between the gears.

No need to split the cases, the power valve mechanism is under the clutch cover. On my '03, I recall it was kind of a PIA to get the cover back on with the cylinder in place due to the cylinder to cover seal, but doable.
