Firstly, drain the fuel tank, lines and carbs. Remove the spark plugs and
pull on the rope a few times to blow all the water out of the engine
cylinders. Drain the chaincase and refill with new oil. Drain the oil
tank, remove all the oil lines and blow them clean. Grease all fittings on
the suspension to clear them of water.
Put fresh fuel in the tank, fresh plugs, fresh oil. Use mixed fuel in the
tank as a safety till the oil in the injector lines starts to come through.
Pul the SOB over till she starts and run it till it is toasty warm - helps
dry everything else out.
If it is too late to go out riding anymore, fog the engine for summer
storage, keeping the fuel tank full with some stabilizer in it. Hope for
the best next fall when you start her up again....
I have also been involved with another, that was sunk in a river, that
was very muddy. It was only under for about 15 minutes, but in that
time, the engine filled up with mud. Of course, the only way to clean
that up, is to take everything apart, and, carefully, wash it, before
putting it back together.
It also matters, if you were at WOT, when it went under. If you suck
in a bunch of water, the pistons will, very suddenly, stop, when they
have no more room to compress the gasses, and that will bend, or even
break, the crank, or worse. If you managed to think about killing it,
before it went under (yeah right), you shouldn't have that problem.
Doing it yourself can be a learning experience, and you can, possibly,
take some short cuts, that a professional could not, but you do take a
chance that it will self destruct if you miss something, or do
What more can I say??? Except, good luck...
