Got caught out in the flooded region around Chesterfield today. Got to one flooded road where cars were getting through with water no deeper than their doors. Decided to go for it. The flood was probably about 150 yards wide where the road was under water.
Got it into bottom, stood on pegs and kept her going - and going, and going. I was doing fine until a truck came the other way - i saw him coming,and he saw me coming so probably thought he would have some fn - at my expense. His bow wave made the flood higher than the screen and so the inevitable happened - all in about 2 seconds flat. The bow wave got me off balance, as I swerved to get more room I hit the submerged curb that you couldn't see in the muddy torrent and the bike went down.
I picked it up again and pushed it the rest of the way out and up a slope to a handy concrete patch that served as a lay by. I got the plugs out (all 4 of them) and took out the air filter which was sodden but in one piece. The air box was a reservoir of water - there is a drain on the back end which I discovered by looking to see how to get the air box off - brilliant, unscrew the stopper et voila - the air box emptied itself. The exhaust obviously had water in it too - because there was a steady trickle of water from the joints, so I undid them and helped speed the process up.
With everything empty of water to the most part I decided to try and spin the bike over without the plugs - the oil in the sight glass was not sitting on a meniscus of water and hadn't gone white either - so I felt there was not much chance of water being in the sump. Pressed the button and she span up and threw out some water from the plugs holes - possibly residue in the intake system.
It wasn't raining so I set about drying as much as I could with the bog rollI carry in the top box at all times (handy piece of kit for long hauls!) - after and hour or so I plucked up the courage to put it all back and see if she would fire up. - She did after a short burst of starter.

There are some brilliant aspects to the design to allow a flooded bike to be emptied at the side of the road like that - and all with the tools that come with it in the tool roll (could be better quality, but good enough). BUT, don't believe all the hype about being able to ford deep rivers - this was only about 18" - 2' deep and the water was getting close to the intake trumpet before the truck came. I am not sure it would not have sucked in water as I was driving anyway. 18" would be fine - but a 3 foot deep river it will not go through and survive. However, I am impressed at the fact it went for so far (a good 100 yards) without faltering. I am also very impressed with the ease of emptying everything. I came home and immediately changed the oil as a precaution, even though it was only done at the weekend and 500 miles ago!!
There was NO water in the oil that ran out - so I feel confident there is no harm done because the engine sounds very quiet and there were no rattles or bangs anywhere - sweet as nut and pulling as strong as before. Even the idle is correct.
Bloody brilliant. There isn't a sports bike on the planet that would have survived half the flood, nor many trailees I reckon either.
My faith has been well and truely bolstered by this - but I will be a little more careful at tackling such long and deep fords again!! Good old 1150A. :thumb2
 
Brave of you to try it at all!

The GSs do have pretty low air intakes and are vulnerable in deep water. Most trailies have the air inlet under the seat.

King Rat....before you ride it in the morning, get your 6mm alan key and check the FD oil via the filler on the bevel box.....very seriously!!

There's a pretty good chance it'll be emulsified......there's only about 380ml of bog standard ep80/90 in there so it's easy and quick to change.


Here's why (and I've had it many times ;) )

You're right though, the 11xx's are superb for it.....be thankful you haven't got a 1200 ;)
 
Just think a KTM 950 Adv would of been fine wading depth about the headlight and no final drive :augie

Glad you are pleased though :thumb2
 
Just remember to piss in the derv tank of the next trucker you see parked up.:monkeypiz
 
water ingress

similar experience, water briefly came over my knees. when I checked everything over the air box was dry(how?). water was in the shaft drive housing but easily drained and sprayed with WD40. since done 140 miles with no problems. Ace bikes

thanks chaps

After reading this thread Ive just drained the final drive oil, uuurgh - mayo. Only serviced it last week. Owt else I should check?
Cheers

Thank you Fanum.
I have only got this after riding to Milton keynes and back (about 250 miles) at a steady motorway speed. No noises form the back so far - but taking heed of your advice tomorrow morning before I do anything else!!!

Even if the oil in the final drive is fine, I don't care. £10 worth of oil for peace of mind is bloody good value i think. Besides, it doesn't hurt to put new oil in early. Any particular preferences for hypoid from you lot?

In the R100Rs I was always very pleased with the orange bottle stuff from my local motor factors - synethtic 75-90 (Tetrasil in one varient or another) and it worked fine in all the drive side. Please bare in mind that I live in the backyard of nowhere, and don't have the luxury of such places as Halfords.....just Motorco and whatever they have in:thumb2
 
All done - Comma 75-90 it is. GL4 or GL5 - depending on which label you believe, the one on the front or the one on the back :confused: Should be fine, better than a casing full of water anyway!

When I drained it there was stll colour in the oil - a LITTLE bit milky, that was all, but certainly not white sludge or properly emulsified. Sure, a bit of water got in, but not enough to cause long term damage - not now my eyes were opend to the potential problem from the members on here.

Grateful thanks for the warning - another little bit of sage advice filed away for long term ownership.

Fanum, if we meet anywhere I owe you one of these: :beerjug:

Cheers chaps.
