Riding home from a trip to Melb this evening, I got caught in a TORRENTIAL downpour, and I mean heavy - I could feel the impact of the rain drops through leathers. Pulled over to let impatient traffic pass as I couldn't see a thing and didn't want to push my luck on wet roads. After a pause of about 2 min I set off again, but the bike (CB250) started to splutter. Shortly after it decided to make 60 the top speed in 5th with the throttle full open. Pulled over again to see if sitting and turning over would help. Set off again, same prob, then it decided to cut out at about 40. Pulled over, and sat for ten mins, checked spark plug connections - rain passed. Started bike and after a bit more spluttering it ran normally. By the time I got home, the bugger was looking at me pretending it had never happened and that it was happy to do 100+. Am I right in guessing that the rain had forced water into areas that don't like water? It's never happened in the rain before, but this was really hammering down. Any tips or pointers would be appreciated.
