Was out twice now with a 250 kaw and at the begin of the day it goes thru water no problem ,but after 3hrs of riding and coming back thru same water holes it quits... spark plug was dry when took it out...air filter had no water in it but did notice and little wet with gas. After sitting for 10 mins will start up. hit next water hole and it quit again. anybody had any similiar trbls?
