Dropped my bike possible damages?

about 2 hours ago, i got on it started it up and "walked" it out of my garage, i stopped and went to put the kickstand down(to close the garage door) and i guess i leaned the bike so while the kickstand went down it kinda hit the ground and went back up, i didnt notice. i stepped off and the bike went down. again the bike was going 0 mph and not moving at all in a back or foward direction i was stopped

it was at 11pm so i couldnt really see anything, i held my iphones light up to it and as far as i can see the only damage is to the clutch leaver(it bent) when i picked it up i noticed that there was some liquid on the ground, directly under it. again i couldnt really see it was dark, but i know it wasnt their before. so im guessing the liquid was oil. after i got the bike back up i put the kickstand up and started it.

shining my light i didnt see any leaks or anything while it was running, turned it off and looked for leaks and didnt see anything.

so im wondering where the "liquid" came from, does this always happen when you drop a motorcycle? i have a 2006 Kawasaki Vulcan 750. i already order the new clutch leaver cause i rather not try and bend it back, to much work.

what could be possibly damage in the bike from dropping it while its stopped and running?
