Hi,
Give yourself a good slap !, I'll bet there was plenty of muddy water sucked in the inlet,
Pull it down and get the crank and rod dismantled,if there is no wear/damage, just reassemble, with new bearings /seals before you ride it again , make sure the water drain in the air cleaner is not blocked.
the shortcut is usually the most expensive route in the long run.
cheers
