I have a 2002 r1 and I got home from a ride noticed the bike had some hesitation and loss of power not much but some also after going inside for about 15 mins to take off my gear I came back out to a small puddle of oil under the bike after further investigation I found it was coming from the airbox leaking out of the front of the intake of the airbox so I inspected the airbox and found a puddle of oil in it the bike doesn’t smoke or anything so I didn’t think it was piston rings but now I’m concerned on what it could be

It´s not uncommon to have some oil in the airbox since that´s where evaporated oil will be routed to by design through that breather hose, just as excess oil will be.
Did you happen to fill up some oil recently? Or was the bike tipped over onto the side?

In any case i would clean it and monitor if it happens again since it´s quite a bit of oil there.
