Glenn is probably right, 5 ozs of water in the crankcase is a very humid environment, not to mention the 'unfiltered' creek water. IF there was terrifc oiling going on you might get lucky though- at this point you have 2 choices- tear it down and look or fire it up and LISTEN CAREFULLY---ALL THE TIME !!! If they start rumbling then get them fixed.
I run any stiff desert rated knobby with TuBliss inserts at 6-8 psi. Tried the trials tire route and it just didn't suit me
