I don't like to cross post on lists, but realize many riders here aren't on other lists I might frequent. If you did catch another post, there is an updated link at the bottom with more pictures for those who can stomach it ;)

***********************************************
Monday March 26th

True to her name, my beloved 'Comet' succumbed this evening in a blazing ball of fire.

I cannot explain what happened, I was out for a ride for about 1.5 hours and as I was traveling on the highway my headlight went out. At the same time, I noticed an electrical burning smell. I was coming up to a stop light, and as I slowed I could see smoke coming from around the tank. Now stopped, I looked down the left side of the tank and just next to my left knee flames were flicking out from just below the front of the seat. I instructed my passenger to get off the bike... NOW! I could see flame just above the fuel injection computer, almost dead center. It and the battery are really the only things there. I tried to figure out what to do, I wasn't close enough to anywhere to get water, the only other thing I could think of was to call 911, which is what I did. After informing them of a vehicle on fire, and the location, I grabbed the helmets and my friend and we moved FAR away from the bike. Two vehicles stopped to offer help. I thanked them and promptly suggested they leave, there was nothing they could do and this sucker was going to light up full bore.

Within 2 minutes the bike was engulfed in flames. I knew there was about 1 gallon of gas in the tank and suddenly backing up further seemed a good idea. Ironically, I realized we were standing in a graveyard watching the show.

The local police arrived first, just as the faring started to catch fire, and they blocked all four directions of the highway. Next, the volunteer firemen showed up, set out some flares and watched along with us. Three minutes later the gas tank popped and flames shot 20 feet into the air for a few seconds. The entire bike was a gigantic ball of fire by now, as the sirens of the firetrucks made the announcement they were on the way.

There was nothing to save at that point. They doused the bike with water and put it out. Flashlights began to flicker over the carcass, inquiring eyes prying for a sign of what caused it, which they also knew would no longer be there. As one fireman was looking at the left side, the rear tire blew like a gunshot, and bodies jumped away from the bike, taking cover. I thought "great, now they probably think there is a gun in the bike somewhere". All was quiet after that and slowly people re-approached the lump. I approached to look at the carcass and the fire had grown so hot it melted a corner off the valve cover.

The only thing that seems to have managed to remain unscathed is the front tire/wheel. All else is charcoal. Ever smell fiberglass burn??? Ew... I can still smell it.

A tow truck appeared, and lifted the lifeless carcass off the road. The driver gave us a ride home, then left the bike on the side of my driveway. He didn't know what to do with it, and I sure didn't have a clue.

I was able to save the Helen2Wheels toolkit case and tools from the tail section of the bike. Only the bottom of the tail section burned, and not enough to ruin the toolkit or it's contents. Whoopie.

I have no explanation for what happened. I have not been doing any work on the bike, everything was in the same order it was in last year when I rode her 20,000 miles. I rode it last week without problem, yesterday a short way to dry it off after washing it, and then this afternoon. If I'd been doing some maintenance, I could lead myself to believe I reassembled something wrong, or did something to the wiring. I have done nothing to it and all leads were fused. I am really puzzled by the whole event.

It was my passengers first ride. She was amazed how calm I was during the whole event. There wasn't a thing I could do but watch, so what's the point in getting emotional over it? She can't say I didn't provide and exciting evening! I couldn't begin to speculate upon the possibility of even attempting to top this one ;)

I'm beat. I'm going to go have a beer now and go to bed. I'll get better pics tomorrow, macabre photos for those interested:

I am happy that you and your passenger are ok though and that is most important . From you discription it sounds like an electrical issue started it. You mentioned washing your bike prior to all this mess. Maybe water got into somewhere????:dunno

Sorry that happened. I've seen the same thing happen to a School bus after being parked all summer.

It was pack rats eating the wiring and building a nest next to something hot.

Good luck with the insurance company.

Sorry to hear of the loss of the bike :(

My K75S caught fire in a very similiar fashion, though afterwards I figured out exactly what caused it (and I was able to put out the fire having just bought two 2-litre bottles of water.)

The prior owner had removed the excess-fuel catch cup ("AIR ACCUMULATOR - #16132307467, see #5 (http://www.realoem.com/bmw/showparts.do?model=0572&mospid=47908&btnr=16_0242&hg=16&fg=05)) which usually resides under the tank and functions as a catch basin for the tank fuel overflow tube, the tube at the bottom of the cup then routes fuel overflow down behind the right footpeg. Without this little cup the fuel just flowed from the rear of the tank all over the engine.

I made the mistakes of (1) letting someone else fill the tank and (2) not watching him do it. I pulled away from the gas station and onto the onramp for the Spaulding Highway when I happened to look down and see a wall of flame covering my right leg. I immediately pulled off and killed the engine, put the bike on the sidestand, grabbed one of the two water bottles (which BTW fit perfectly between the rear bag handle and rear cowl) and doused the bike. I followed this with a second dousing. A few minutes later a guy pulled up on a Harley who happened to be a bike wrench - after pulling various bits off the bike the damage seemed to be limited to a thick ground wire and a yellow wire at the edge of the loom. Harley rider pulled out some electric tape and in no time I was good as new, with the exception of a slightly singed Aerostich leg.

I opened the tank cap after the wire surgury and fuel just flowed out, the guy at the station had filled it to literally overflowing while on the centerstand - I am sure the second I leaned the bike the fuel began overflowing in force. I got a new air accumulator ("Cup") later that trip and was happy to be able to fill the bike more than halfway (preventative measure.)

Sorry for you loss, glad you're alright. Now go shopping...
And the rest of us K bikers, check your cup. ;)

WOW, very humbling looking at that...

Sorry you lost an old friend, but glad no one was injured with the tank pop..and you were not between destinations in the middle of BFE

One can only guess that it "acted like an old Fiat" and decided that the insulation between wires was a bit too thin.....and a non-fused short occured and that is all it takes.....

I have a friend that just saved his RT by noticing an electrical short in the main harness...at a zip tie that came too tight from the factory....

I suspect that this is far too common a problem.....

Hope you have good insurance....

Yikes! I'm not sure I could get on another K bike having had one incinerate itself out from under me. A rare, freakish occurence, but still.....

Note to self: must get a small Halon fire extinguisher for the tank bag.

Yes, fortunately, my deductible is only $100 :) They stopped by today for their own photos, now we begin negotiating what it's actually worth. I'm STILL trying to figure out all the stuff I've added to her over the years... *just* recalled earlier I'll need a new Garmin power cord... boy this stuff ADDS up!

And finally, I love my Mixit2!

VERY glad to hear it! :) Mine was in the tankbag, safe in my garage alongside my Valentine and new 2720 GPS... thank God for even small favors ;)

I rode it the day I washed it, and this was more than 24 hours later... I can't imagine water still played a role, but anyone's guess is as good as mine, there is nothing left to look at to try and figure it out.

I used to keep my prior bike in a barn and mice had built a nest in the airbox one year. Since then, first ride after winter beings with an inspection of airbox, and wiring. I didn't notice anything. I could have easily overlooked something though... and did not remove the tank to look at wiring under there.

Slightly singed leg?!? Yow... sounds like a real hot seat! ;) At what point did you put the leg fire out? Before or after the bike??? I might need that knowledge should there be a *next* time (hopefully NOT!) I definitely had the overflow cup in place, last winter I replaced the drain hose because it was looking a bit weathered and cracked. The fire started a bit slowly for it to be fuel... I think...

I've been considering one of these:

BOY halon is expensive! But it works from what other riders have told me.

I will be holding a little farewell party Saturday, 6PM. I'll burn some burgers, light a candle, set off a flare... you know, maintain the theme ;)

((OK, minus the flare, I don't want the fire department visiting again))

Come along, or raise your favorite beverage in this general direction:

A halon or soap based extinguisher is a good idea but if the fire is electrical in nature may not solve the problem as the short is supplying the heat. That's one of the reasons I intensely dislike non fused items on the bike like headlights. I can understand the starter but the headlight does not need a straight hot line to the battery IMO.

Glad you got off without injury. Hopefully the insurance will cover the loss.

True. But an extinguisher will buy a little time to cut a lead to the battery.

Running the headlight directly to the battery (through a relay) on a K-bike A) makes the headlight brighter because BMW used too small a gauge wire, and B) prevents the headlight switch from destroying itself because more current passes through it than it is rated for.

I am thinking about adding a battery disconnect in the next one, which should stop any electrical fire short of the battery itself malfunctioning. There is only so much we can do to protect ourselves and our bikes ;)

State Farm is offering more than I paid, and we haven't added the accessories yet. They have once again been VERY good to me! And/Or I got a better deal than I thought when I bought it!

Sorry to hear about the bike :cry

Halon is probably not the best for an open vehicle fire (actually, it's not Halon
but probably FM200, a Halon replacement). A dry chemical extinguisher, while
messy, is probably your best bet.
