Great RR, as usual - love the towing pic, Prutser!
I did not fix it yet.Although it was better after I squeezed the brass vent tubes that are in the float bowls.
Would love to have a chat about this problem. But it might be better to do so in the http://www.advrider.com/forums/showthread.php?t=375091 thread.

Water danmage to your steed

If the engine's still running when it sucks in water, you potentially have the sort of damage in the photo above.

If you turn it off as you fall in, or push it through deep water with the engine off, you'll get water in the airbox and probably exhaust, and unless the engine happens to have stopped with all the valves completely closed, it will end up in the cylinders. Even if you try and start it you won't bend conrods, etc, because the starter won't get it spinning hard enough, but you won't be able to get it running until you take the spark plug out and turn the engine over to pump it out.

If your bike has a crankcase breather which runs into the airbox (as a lot of bikes do), then the water in your airbox will inevitably flow downhill into the crankcase, and ruin the oil. This is A Bad Thing. I've done it twice to my XT660Z, so was utterly unsurprised on reading one of Colebatch's previous reports to find that Terry had done the same to the XT660R he had on that trip. I have a simple mod in mind to prevent it happening a third time (of course I thought of doing it after the first time I went swimming, then didn't actually manage to do it before the second time ).
Francesca.
All the above is true and learned by the usual painful experience, but please don't be frightened of water crossings. As you'll have noticed Beemster was worried at the start of the trip, but in no time was splashing in without fear.
Engines have indeed been damaged and electrics fried -but a bikes rear wheel contact patch is too small to allow you to go tearing through deep water, and if you're going to go down or over, you'll usually know before it happens and be able to kill the engine or at least partially catch the bike on the way down. On one day of this trip we did about 40 crossings, some very deep and I think (but may be wrong) all of us binned the bikes in the river without damage. I certainly did, Walter and Terry maybe did 500 crossings this year without any significant problems. You'd have to be pretty unlucky to wreck anything so please don't let this put you off river crossings, they're some of the best and occasionally the most challenging bits of overlanding. Just be careful and enjoy.
One of the best bits is seeing your mate go down......as you'll I think see on this trip soon.

Could you elongate the breather tube to cure this in the future?
Doesn't look possible if someone chose the locking cap...
You have been using the non locking-cap for X-tank?

On Walters bike the engine air intake is about 5 cm lower than the fuelcap breather hose ! (unloaded bike)
I think you could use a longer hose for the breather. So you don't have to watch the tank's breather and worry about that !
Although you are getting close to the max depth the bike can handle at the front.

Hi Walter and Co.

Just wondering if you have considered carrying something like this:
along?

As used by MetalJockey in this report:

Just pondering.....

Never for a minute, no.

They are very bulky. And from talking to a guy who has used them, they are insanely time consuming.

There were no rivers we could not cross without any floatation devices.

Day 39 Continued

Terry's towing got me to the town. I had tried to start the bike on the way a few times, and while it fired up occasionally, it generally sputtered out and died.



We decided to go to the village store. Everyone was pretty hot and needed a drink. And I needed 220 volts to plug my battery charger into. i would try and charge it up via mains power.



Terry towed me one final time a few hundred yards down the road to the village store:

werner747,
There was a discussion earlier about pontoons.
The general consensus was:
Too heavy. Too bulky. Too much time. Too dangerous with ANY noticable current. Not worth it for these trips.

Prutser,
I understand the front submersion depth is important only if engine is running, risking permanent damage. Otherwise water can just be drained from airbox and blown out, as demonstrated.

What I don't understand is the rear depth (X-tank case):
Even if the engine is not running and hence not pulling fuel through, would river water still get in through the breather just by virtue of it's own pressure? I can only assume so based on the amount of water Walter's bike was dealing with....

Well my engine was running when the ass end of my bike dug itself into a hole, so actively sucked the water in. Not sure what would happen if engine was idle re the fuel breather ....

You've also mentioned that the air temperature was high so when the tank was submerged in cool water the metal would quickly start to cool the fuel which would reduce in volume and pull more water in. Any vapour condensing would add to the problem.

Brilliant report and an amazing trip. Thanks for taking the time to writ it up folks.

Yup, I became a convert of the peg to peg method of towing after my (loaned out) DR made a deep crossing and my KTM ( which I was on) did not.

Brutal shit to even push a bike through. When the fellow towing me hit a graded dirt road he whipped up to an indicated 70mph before the strap slipped from my footpeg, so I snicked her to third, dumped the clutch and the bike awoke.

Nice RR so far, waiting on the real gnarly bits here
