Ran with gas in the oil, how much damage did I do?

I have a 1995 Suzuki Savage 650, single cylinder. It has a 3-position
fuel switch: ON (which automatically becomes OFF when the engine is shut
off), PRI ("Prime", which bypasses the automatic OFF), and REServe.

I had it parked in the garage all winter with the switch in what I thought
was the ON (/OFF) position but it turns out it was in the PRI position...
that's what I get for trusting memory and not getting down there an
actually LOOKing, or RTFM'ing... :-(

As a result there was a LOT of gasoline in the oil by the time I got it
out of storage.

I checked the oil level and then took it out for a short ride (three or
four miles) to warm it up. It really wasn't running all that well... ran
OK while moving but wouldn't idle without shutting itself off. I then dug
out the manual (imagine that!) and discovered my error. Drained the oil
and sure enough, there was lots and lots of gas in with the oil, probably
more gas than oil, and the crankcase was seriously overfull.

I filled it with clean oil and removed the filter, and put the filter
cover plate and gasket back on (it's a filter cartridge that goes behind
a plate) so I could run it a bit with clean oil and without a filter and
without it leaking. Then I ran it for a mile or so and it seemed to idle
much better, actually runs now just as well as it always has. Couldn't
hear anything that sounded like rods knocking or lifters clicking, not
that I'd necessarily hear it over the normal noise of the bike.

My wife has gone to get another filter and I plan to run it for a couple
more miles and then drain the oil again and replace the filter cartridge.

My question is, how much damage am I likely to have done by running it
with all that gas in the oil?

Is there anything else I should do to mitigate any damage that may have
been done, and prevent any further damage, other than draining the oil
again and replacing the filter cartridge?

For example, should I run it for a short distance (10 or 50 or 100 or 500
miles) and then change the oil again?

Any problem with running it with no filter cartridge for 50 or 100 miles
and then draining the oil again and replacing the filter? I am assuming
that oil will just fill the filter compartment and run through the engine
without restriction, actually with less than normal restriction since
there is no filter.

Any kind of additive I can put in the oil for the next 50/100 miles to
help mitigate any damage? (I vaguely recall back in the 1960's when I was
pumping gas for a living, the gas station mechanic told me that cleaning
engine parts in gasoline causes oil not to stick to them anymore, reducing
the lubrication capabilities of the oil.)

I'll hold off on doing anything further until I hear from you guys ...
thanks...

 

Erk :-(

Wise move.

You *might* accelerate the overall wear on the engine by thinning the
lube, but it's the sort of thing that won't show for ages and ages,
and as you only ran it for a short distance and not flat out, you
probably haven't harmed it.

Nope. You've done the right thing already.

Don't do this. Really.

No. Snake oil, all of it. You've done the right thing already, and you
should be fine.

 

Thanks to all for your help... changed oil again, installed oil filter,
removed air cleaner per Albrecht's suggestion (no gas or oil in the air
cleaner compartment but the filter element is a bit dirty so I'll replace
it), ran it around the block a few times, guess everything is OK and I
dodged the bullet yet again.
