Well, I got hit at the most inopportune time, which was while crossing deep
creek in a race. I went face first into the water. I got up and looked at my bike
and it was completely submerged! F-Word! This was within the first 20 minutes
of a 2 hour race. I wasn't about to give up, so I kicked and kicked. I turned my
bike upside down and pushed through the kick starter.

Finally, I was able to get it running with the choke on. Then I was able to rev it.
I took off on my bike, and it quickly started running flawlessly.:thumbsup:

I finished at 12th place, and we figured I spent 20 minutes trying to get my bike
started according to the lap times. My best lap was only 1 minute slower than
the leader's. Damn, that really hurt my overall. :ride:

So, I'm wondering if I did any damage to the motor? What should I do now? I'm
planning on changing the oil + filter. Anything in particular that I should do?
Do you think since I rode the hell out of it I have now compromised the
reliability?

I don't know. I just got home and haven't changed the oil.

change the oil a couple times and run it at idle for a couple min so the new oil gets into all the parts just to make sure you get all the water out, change the airfilter, drain your gas, and i think thats it. o yea your might want to repack your muffler

Cool. Thanks bro. I did all that and it seems like everything is fine.

Is it worth changing the spark plug? It is pretty new.

Yeah! It ran great the entire rest of the race! Should I change the plug or do
anything else? I just want to be safe.

How did the oil look when you drained it? Milky, or more or less normal?

The problem with water in the oil is that the detergents/dispersants emulsify the water and it turns the oil int a nasty foam that won't lubricate anything. If you ran it with oil that looked like that, you should pull the cam caps off at the least, and see if you can detect any damage.

then water did not get into the carb...it would have been hell to start and would have ran like crap.
Water could have been sux'd into breather tube - how did the oil look?

It was hell to start after I dumped it into the water. It took me 20 minutes to get it fired up (this is during the race). Once everything cleared up, it ran great.

The oil looked very thin. Not too bad though.

if water was sux'd into the motor from the breather tube,,,the oil would be greyish/milky........if yours does not look like this you are good to go:thumbsup:
