drowned bike

[ez]

anyone had this happen? my son droped his kx100 in a big mudhole only thing you could see was the left grip. would not restart. we got it down the mountain he cranked it ran a little. i stopped him. the oil was milky. i think the water went in the carb via the airbox. I have it all out dowm to the carb . drained the carb gas looked good let new gas in drained the oil put about half back in. rolled it over in gear with plug out.took the packing out of silencer(didnt seem wet i don't know how) i checked it has spark.I thought about spraying wd40 every where i could to remove moisture.i am about to try starting it.just wanting to know if there is something i am overlooking? this place is great for anything kawasaki or 2 stroke related. thanks

Change gearcase oil till its clean. Make sure as much water is out of cylinder/crankcase as possible. try to get the bike running as soon as possible. Removing the moisture is #1. A teardown would be preffered if possible as dirt/mud in the water will cause wear or even damage. had an outboard go under, got it running in just a few minutes and thats all it took, get fresh fuel/oil ran through the motor and will probably be fine

From what I've heard this is what should be done:
remove plug, carb, dry air filter as much as possible.
put bike upside down to drain water from pipe and silencer
kick it to get water out of cylinder
put everything back ride home.
Take everything down and do a thorough cleaning of carb, air filter, plug, change oil till it's not milky. done.

oh I forgot, ;ast thing on the list:
atomic "dopeslap" to the kid...don't do it again

You said he submerged the bike in a mudhole, just how muddy was the water?

If it was clean water, then I won't bore you with a story about my son seeing how his RM60 would work as a submarine.

do you mean drowned,.......like this??

[scheckaet]

That one must have been fun to get out...double atomic dope-slap is in order then

i was just tring to see if atv=jetski .............i found out "NOOO!!", the hard way!

[ez]

yea pretty much like the pic and he stood there looking at it..dopeslap unnecassary pushing/dragging bike down 4 miles of mountain. might have done the trick.worse is it was only the 4the time he has gotten to ride that bike.now i am trying to figure out how long this resurrection should last .oh and i forgot to mention we traveled 2 hours to get there.rode 20 min.and sank it.wasted day,

One of the worst things about a severe dunking is that the water will flush all kinds of dirt particles from the air cleaner into the engine. These dirt particles will reek havoc on your piston, bore, and main bearings. Unfortunately, other than a complete tear down immediately following a drowning like that, the best you can do is get the bike running right away, to blow everything out. As previously mentioned, change the gearbox oil repeatedly, until the milkiness goes away.

[gregp]

Also, you may want to disassemble and clean the carb, and boots very well because those dirt particles can cause a stuck throttle very easily.

The water in that picture is almost clear compared to the mud hole my son submerged is little 60 in.

Muddy water made its way all the way into the crankcase. I repeatedly flushed the bottom end with premix until it came out clean. I still had a bad feeling about it and split the cases.

I was glad I did because there was still mud around the bearings. I'm sure that stuff would have dislodged at some point.

ATF will get water out.
