My experience thus far with over a dozen stalling incidents in moderate to heavy rain leads me to believe that there is a genuine problem.

Having owned over 15 bikes, I had never experienced a problem like this before.
Had I not been able to fix the stalling problem on my bike, I would have considered selling it.
IMO even a one off kind of a problem should be given immediate attention by BMW, considering the premium price you pay for admission.

I don't know. Rideable? Absolutely. Does it matter what you call it? I find it rather odd for you hide behind semantics given your borderline obsessive approach to certain other relatively minor issues, but I find it quite dissapointing that the engineer would do the same...assuming you're conveying his point accurately.

In my case, I was absolutely not riding in unsafe conditions. I've been in unsafe rain. I've pulled over before. I've been in unquestionably torrential rain in Florida and the Carribbean and equitorial South America, and the conditions I was experiencing on the GS in California were a far cry from any of those tropical squalls.

I completely agree with that logic leading to a potential cause, but until BMW (or, more likely, some inmate) finds the smoking gun, I think its a bit presumptuous to call it a "closed case. Unfortunately, the only real data point I've seen (and granted, I haven't looked that much) is in the stalling thread where one dude blocked off his intake ducts and couldn't replicate the stalling.

So, by default, the score on my whiteboard is 1-0 in favor of water in the airbox.

It may not be such a drastic fix, bxr140. I don't know if you've had a chance to peruse this thread over at F800Riders.org, but this guy's working theory is that it may be a gas tank venting problem that gets caused by heavy rain. If that's the case, the fix may be as simple as unkinking a vent line that got installed wrong at the factory, and not require any redesign of the air intakes or filter housing. This would explain not only the fact that not everyone is affected by the problem, but also the PUMA bulletin about gas tank venting problems. Who knows? I certainly don't. But it would certainly put to rest any inane nonsense about not riding in the rain, torrential or not.

Mine has stalled numerous times during extended trips in heavy rain, not necessarily torrential, but after a couple hours it will quit while decelerating to a stop light or something. I've experienced similar problems after riding around in creeks and rivers, nowhere deep enough to be affecting the air ducts. So I don't know, but there's something wrong. That and the poor seat are the only diminishing characteristics I've found with the bike in 8,000 miles. I haven't experienced these clunks I keep hearing about.
I do have to wonder why this engineer would be checking the water levels in an airbox if it wasn't stalling the engines.

Look guys. I'm only posting my result here, and what I was told by a very experienced person from BMW. If you don't like what he said to me about my concerns, take it up with BMW. Don't go bitchin at me. (Especially you, bxr140)

I didn't have to post the FSE result. I thought maybe you guys would like to hear about it, being this is a forum.

When the FSE said torrrential, he meant torrential. Not just a shower or even a heavier shower.
I've ridden my '08 KLR through TORRENTIAL rains on more than one occasion and I've never even come close to stalling . And I'm talking about tropical, South Florida, near-zero visibility, flood-inducing, build-an-ark kind of torrential rains. I've also ridden it through 2+ miles of water that was halfway up the bike and surging up and over the cowling. It did stall once in that situation but it restarted immediately.

Just thought I'd throw that in there

If that BMW FSE dude can fly here to San Diego I have a spare bedroom and lots of extra beer if he will look my bike over....plus I can drop him off at the largest Motorrad dealer in SoCal so he can converse or otherwise hobnob with the fools I dealt with. My fine BMW F800GS died on me in the rain (died three times in less than 2 miles). The storm I was riding in was pretty light by all measures. I took my bike to the dealer and they replaced a number of items....but refused to give me a list of what they did. Unfortunately, I live in San Diego where is rarely rains so I will have to wait for my next trip out of state to test the bike. As was pointed out earlier, some of the issues with the 800GS are not universal, however, there are some trends. Stalling, loose steering head bearings, dysfunctional gas gauge and front fork noise appear to top the list. I think we all started out very excited about this new model bike, but for people like me ...neither my bike nor the support network has lived up to expectations. It is great that some folks have had positive experiences with their bikes and dealers....for the rest of us some of the issues are getting old....I just want to ride the bike....I do not care that BMW has comfortable couches and free gourmet coffee....the Roundel is not much of a status symbol when you are sitting on the side of the road ....with your thumb out!

Right. You knew exactly what you were posting, and you got exactly the responses you wanted. So why are you complaining?

Just stumbled on this thread. I have a DR650. Not long after I got it new it started dying in the rain. It got worse to the point of dying riding on a wet road. I could not get it to quit in the yard dousing it with a water hose. If I took it to the dealer they would just keep it for a week letting the Techs ride it to lunch and then tell me there was nothing wrong with it.

Anyway cutting to the point, after waterproofing all the electrics with silicone and it still died in the rain. I replaced the spark plug caps with NGK's. It hasn't stalled (quit) in the rain since. And I have ridden it in torrential downpours.

Good luck, Gus

Myself and a friend rode our F8s in torrential rain, she for 2 days until she called it quits, and me for 3 days solid, neither even hiccuped, and we where absolutely drenched. There is no rain problem from my experience.

Rain riding

No one seems to have nailed down this "rain" problem. The assumption seems to be that water in the airbox is causing it. Engines don't really have a problem injesting water. The technique is used to remove carbon buildup on cyclinder tops. You can spray a lot of water into a running engine before it stalls out even at idle. At highway speed you are pumping so much air through it you would need a garden hose to snuff it out. Is the air filter being saturated? If it was it would seem likely that the bike would not restart right away as some have said it did... Maybe the water is affecting a sensor or wiring connection. That would explain why some people have it and others don't. If we can stay away from calling each other liars and such we may be able to track down this glitch using a little logic, some common sense and a little courtesy. The fact that not everyone suffers the same problem would seem to indicate that it is not an inherent design problem but quality/assembly issue.

Exactly what I said earlier. Has anyone who suffers from this problem investigated the venting scenario mentioned by the guy on f800riders.org?
