GS flooded water in oil

[AArman]

Hey all

Done some trail raiding with my GSa. And when crossing some deep waters, some of it got sucked it.
I immediately changed the oil. But will be doing another one just to be on the safe side.
Anyone could recommend anything else? Was thinking about one of the engine flush for cars but not sure if its ok for bike

Should be fine as long as engine was switched off as soon as water got in. Any residual o2 will evaporate with the engine being hot after you change oil. Just my ramblings but im sure all the experts will be along shortly to tell me im an idiot. Hey ho

Did the water get sucked into the sump? JJH

I didnt notice it right away. And had to ride bike back to civilisation. Went to a garage bought 4 litres of oil. Drained condensed milk and poured fresh in

FWIW...

I got water in my 1150 a couple of months back. Did a road-side oil change within 10km, albeit without changing the oil filter. Did another oil change (again didn't change the filter) 100km or so later. Did another oil change a few hundred km later, this time changing the old & air filters too, and I used a Wynn's engine flush for that last oil change. All seems good. I might be inclined to do another oil & filter change (and Wynn's flush) in the next 1000km or so, but I suspect there's no actual need, as everything seems to be OK.

Thank thats what i was wondering about. Read somewhere that flushing is no good for engine

I would also change final drive oil and geRbox if it's not an LC

not a GS .. but..

I tried to drown a Honda PCX a couple of years ago.. It ended up on its side in 2ft plus of water. I hit the kill button as soon as I could and stopped the motor before it hydraulic'd.
the usual stuff - up end it and empty the exhaust, air filter out. being rev and go and no kick start it took a bit of getting going again, cos it all had to be done on the button.. But run it did in a fashion. 3 miles to work ridden. started first go at lunch and home time..


I had to change the oil 7 times before it was anything llke oil colour and consistency. but it was fine after that and I ran it for another 16000 miles after that with no problem.

So best thing is do few oil changes with filters. Final drive and gearbox.

Flushing is ok on the 1150 as it has a dry clutch. Never use engine flush on a wet clutch, unless you are subsequently going to replace the clutch.

For what it's worth I flooded an old Mini 1000. It kept going on 2 cylinders (wet distributor). I did change the oil but had no chance to do it before a long drive home. It was bit murky but the car did another 40,000 with me with no problems. Oil pressure remained just the same before and after. So we can get a bit too precious about these things. As OP has done, change the oil ideally with something really cheap run it for a few miles to get it fully circulated then change it again. The really fussy can do a cheap oil change and keep it for 1000 miles but if it remains clean there should be no problem.

IME with the Mini as long as its not got a massive percentage of water, the oil will still do it's job. But water will cause internal corrosion so it has to be cleaned out.

Thanks chaps
Ordered 8 litres of cheap ish oil with 1 filter
And will do last with castrol and KN filter to finish with

Thanks for the input guys.
Will do a snorkel to avoid this next time

Yep.
I did drown my R1200GSA in a massive puddle a few years back, being the idiot I am.

First dealer told me to bin the bike due to the cost of a replacement engine.
Another dealer actually took time to "clean"/flush the engine (and inspect it by opening at my request when paranoia set in, but probably this could have been avoided).

I think I've done another 20k miles on it so far and she is going fairly well I'd say, this is last June:

Expensive cock-up though.

 

[AArman]

If flushing what to use ? Any recommendations?

I would simply use the cheapest 20w50 and change it out again after a few hundred miles. It's more than adequate for the engine's needs but has a shorter working life than more modern oils. Swap the oil filter as well because that WILL trap water and then it just gets circulated again.

The bike needs to be ridden for a good long run to fully evaporate any remaining water. A quick trip to the shops will never get it hot enough for long enough to shift the remaining water that settles into the corners of the sump, heads, oil filter, etc, etc. Small amounts of emulsified water wont hurt the bearings but it will cause corrosion. Water always get into the oil from cold starts and short runs but we don't really worry about that issue.

The real water damage happens when a bike drops into deep water with the throttle open. The sudden hydraulic lock will bend conrods and even damage the crankshaft. This hasn't happened (AFAWK) so just change the oil and ride it.

I sucked in water through the air intake when crossing the flooded Danube in Romania on an '05 GS about ten years ago. Bike immediately died, I jumped off and the water came over my boots. gave it ten minutes and turned it over, both cylinders submerged, and it fired up.
Rode back to the UK, via Istanbul and the Balkans (20 countries in 20 days) without changing the emulsified oil. Bike was perfect, in fact a far better engine than the '09 SE I currently ride, I reckon the emulsified oil loosened things up a bit!.
