Read the prophets of doom in previous posts.
Your sump holds circa 4.5 litres of oil.
Have you ever poured 4.5 litres of oil onto the floor?
the mess is incredible. Your description suggests it is unlikely more than a litre ran out, or you would have noticed the total mess.
Since the engine will happily run with as little as half a litre of oil in it, and you stopped it without hearing any rude noises or seeing an oil light, why should it be damaged in any form?
Just tighten the filter, top it up and ride away.
Some of the doom mongers are also imagining the bike can suffer damage from ticking over from cold for 10 minutes.
Can't think why.
The engine has a large collection of fins to shed heat. At a tickover these are more than adequate to shed the heat generated by the minute quantites of fuel being injected to keep the engine running.
I was a judge of fact at a rally last weekend, and conditions were very foggy - & cold. I was on bike, with a front lighting load of 231 watts, which I kept on, facing oncoming traffic, whilst sitting at side of road for over 35 mins at a time, with engine running. (Arrived with hot engine.) After this time, temperature had just risen above mid point.
After 45 mins, at 3/4. Rode 200 metres. Temperature back down again.
So: Prophets of doom, Is my engine wrecked too?
Can't think why. Just parked bike up for winter. Will go out at end of February, switch on, hit starter button & go for a long ride, without checking oil level, which I haven't looked at for the last 2 months. Might kick tyres, but if bike is not all over the road, should be ok.
O Ye who are obsessive, relax a little & ride the damn things. Quit worrying & enjoy yourselves.
