drink

I have a Husa 08 550. it took a drink of water this weekend in a river crossing. I managed to get it started and back to the truck, it was not running well at all but got better as i got closer to the truck. Apart from changing the oil and the filter, I'm not sure of all the appropriate steps...

i usually run my bikes on Avgas because of the crap fuel we have here. Will it be okay to run an 09 on Avgas or are there catalytic converters, or o2 sensors that the lead will ruin?
