hey have a quick question, im in the process of looking at a bike. owner says it was taken out of storage and

"...it started on the second round of cranking and sounded amazing..."

i have no idea what that means, i tried searching and google it, all i came up with something about flooded engine?
can someone clarify if this is normal after its been stored for a long time and it is the first initial start?

its a ninja 250 with 12-13km if it helps.

thanks!
