I replaced the oil pan because the previous owner stripped the threads of the other oil pan and helicoil didn’t work. Apart from that the bike has been running good, starts right up clutch engages properly and the only thing it has is a tune. It did have original oil pan because there were no signs of previous replacement unless the motor has been dropped. And the pin was all the way at the bottom of the oil pan, it was visible through oil drain hole. My best guess from looking at diagrams it’s a pin from the clutch starter
 
A Time-Sert probably would have worked but the kit is expensive because of all the parts and you really need a specialist to install it. Anyway you're past that.

I think this is your idle pin:

It sounds like the previous owner was working on the starter and/or generator, removed the pin for some reason - dropping it through the nearby hole in the crankcase, and decided to let it be. He must have replaced it or the starter wouldn't work. It's the work of a master mechanic.

I was thinking the same thing. It’s good to know I wasn’t far fetched. Over winter I’ll probably open the starter clutch to see if everything is good, but currently bike works great. Thanks for your help and reassurance.
 
Here's a pic of the left side of the crankcase:

The large hole sits above the rotor. The connecting rod would be visible through it. The boss for the pin can be seen above and to the right of the big hole. The hole is easily big enough for the pin but anything that falls through it has to deal with the crankshaft and its counterweights. There are several smaller but still significant holes that are lower and at least partially obscured by the rotor. Many, possibly all, are big enough for the pin but the rotor and starter gear might be in the way.

P.S. If it's not obvious, you could remove the generator cover and check how much clearance there is between the starter gear and the crankcase for a dropped pin to slide down en route to one of the holes.
