A guy I know kinda sorta dropped his WR450F in a stream. (Really a guy I know, not me.)
I'm not sure his bike hydrolocked, but it did quit and lots of water came out when they turned it over.
I think its been run since it was dropped, but it hasn't been ridden.
What would you check on this bike before running it ?
What service work would you do before taking it on a ride ?
If you took it to a dealer, what would they do ?
