She's a goner. 



Dead BMW K1200S

   Wow - everything got chewed up when it went to lunch -  so sorry D2R - glad it didn't throw you when it blew!

jesus...  any idea how that happened?

Aw, man.  Grenade'd      Very sad to see this; that was a cool bike.  Let us know where we can send flowers...

Crap 

That's ugly. Sorry man, I know you love that bike. I gotta think that doesn't happen very often to those bikes.

What is it Steve Machette says when an F1 cars blows up...................KABLAMMO!

That hurts just to see; sorry for your loss.

...so you'll be riding the Monster in the HC?

Bummer 'bout the Beemer

Wow. Only seen that happen on an early 1981 GS1100 Suzook. Looked like it had been hit with a RPG. Now what do you do? Repair cost could be more than the scooter is worth. Really sorry to hear about this. My condolences.

Thanks man... the guys at the dealership said I was definitely lucky that my RPMs were high enough to churn the internals instead of seize 'em. (New band name idea: "Churn the Internals")

Dude, how many times to I have to tell you... it's William! Sorry to snap at you man, it's just that I get that all the time, people thinking I'm the messiah and all. 

There's two theories at this point. (keep in mind this is what my feeble, non-mechanical mind understands of the situation. I ride em, I don't fix em. before all this happened I thought there were little hamsters running on wheels in there)

1) There's a known issue on the earlier K1200S'  (2005, 2006) with a faulty cam chain tensioner. It's very rare that it's a serious problem, but it's recommended to get the fix done just in case. I had parts on order and was planning on getting the new updated tensioner, sprocket and chain before the H.C. trip. If this was the culprit, then it jumped time.

2) With the case open you can see on the video where the service manager tapped on the loose oil pump chain. We don't know if it was loose before the "big bang" or if the rod came back and hit it, loosening it afterwards. If it was loose beforehand, there might have been a failure at the oil pump, causing it to starve for oil.

I did notice a distinct loss of acceleration right before "the bad thing" happened. Usually at about 7k rpm there's an instant and noticeable seat-of-the-pants boost to be felt with any throttle input. I was probably at about 8k and was noticing it wasn't there anymore. In hindsight, this was when things were starting to gum up and that could be explained by theory number 2. Not sure if theory number 1 would have produced a similar feeling.

Thanks Lisa, there will be a wake and memorial service in the near future.

Yeah, I always thought I'd have her for a long time. It's terrible when a loved one dies before it's time. On the flip side, to quote Neil Young, "It's better to burn out than to fade away."

Bummer indeed. Not sure where I stand on HC now.

A new engine would be at least $4k so I'll probably be parting it out. My boss has expressed interest in it as a project bike but we'll see how serious he is when it comes time to talk price.

Dude, this cracked me up. When I went to the dealership to check the bike out after they opened her up, it seriously felt like I was stepping into a morgue. There she was, lying on the gurney lift, her life fluids draining from her heart. I didn't even get a chance to say goodbye. 

if there was a service recall then couldn't you, in theory, pregnant dog at them and tell them it's a known issue and it should be replaced?

would this fit? http://cgi.ebay.com/ebaymotors/05-BMW-K1200LT-K1200-LT-Engine-Motor-Assembly-_W0QQcmdZViewItemQQhashZitem4aac8541acQQitemZ320721994156QQptZMotorcyclesQ5fPartsQ5fAccessories
can't remember if you have an 05 or 06

I sure as shit no mechanic at all, keep that in mind................

If what I see protruding out of the engine case is the crankshaft end of the connecting rod then I don't know how the timing chain could have been the problem. If the chain jumped time it would jack up the valves and possibly the top of the piston, NOT the bottom end.

To my simple mind the only way that the bottom end of the connecting rod could come off the crankshaft is a failure of the connecting rod itself (barring a catastrophic failure of the crankshaft).

Just a guess from a guy that took auto shop back in '85.
