K1300GT blows chunks on TV

Another bad day for a K1300GT and on TV.



These K1300GT's were specially outfitted for filming the Giro bicycle race and one over heats and acts like a Honda.
Mine's gotten hot before, but never went down like a Honda CBR or two that I know which leave a trail of fluid much like this GT has. No clue as to whether it runs again.

I'm sure it must have been rider error....cause remember....all the troubles were sorted out with the 13's.

High performance, high-compression engines need airflow to cool properly. Running at a near walking pace for long stretches as the pedal bikes struggle up those hills simply doesn't allow much airflow to the bike's radiator.

Add in a radiator that has been collecting crud for a while and thus has reduced cooling efficiency, and the chances of hitting a critical point increase significantly. Plus I figure he was watching the bike riders much more intently than his own gauges.

Still, it sucks, especially when it happens to you . . .

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

If crud or bent fins are blocking airflow through the radiator, that's one thing. Assuming that the radiator is clean and undamaged, doesn't the fan draw enough air through it to avoid overheating problems?

Can someone explain what the photo is showing and what the failure is? Are we seeing radiator steam? Burning oil? Something else?

I'm sure it was a BMW design flaw.. Probably related to cam chains...

I agree it looks like coolant spewage. But when yours blew could you contribute any of it to slow paced riding? If the fans are working and it's not clogged up otherwise shouldn't matter what speed really. You traced yours back to a clogged thermo or something didn't you? And then the head warped? Did you get a steam bath out of the deal?

Well, I was climbing a gravel mountain in 1st gear at the time, so high rpms and low speed exacerbated the problem that already existed. Plus we figured out later that I was low on fluid due to a slow but steady coolant elbow leak that had previously gone undetected.

My first indication was the overflow tank blowing out (since the pressure release cap didn't release), and thus spewing hot coolant all down my leg.

So yeah, that billowy, white cloud is all too familiar . . .

Aren't the BMW's just wonderful and reliable bikes. They'll probably use Harleys next since they let their stuff idle out in the desert in their sales promo videos to see if it'll blow up.

Madam Poot is predicting the BMW R-Boxer whatever with a new radiator will be a splendid design with a 3-year design change for maybe a 50cc gain -- and to get rid of some other 'minor' flaws.

Oh, you can ask Madame Poot a question about your current BMW here.

Okay, I just typed in: "Will my BMW K1200GT last?" in the above link and got this back: "Outlook not good... but it can still change..." What the hell is that about!

Crikey! Look at this - and I ain't kidding either!



What the F*** is that about? Madame Poot got a direct line to BMW Motherland or sumptin?

I notice there' another one next to it w/o a problem, but the Chicken Little's can probably spot an impending failure in that one as well.

"I notice there's another one next to it w/o a problem, but that's not nearly as interesting . . . "

There, I fixed it for you.
