The danpalooza is from Phoenix. There was a flash flood in the Phoenix area in September last year.

In the first picture that was posted I see mud on the cover and a distinct dirty line near the intake snorkel. I wonder if the bike was submerged and hydro locked?

That could have damaged the rod and it broke later.

Interesting but....danpalooza, could you please take out the rear cylinder spark plug and let us know if there is any water in there?
Thanks.

Pretty sure that was just dust caked on there. It gets pretty dusty 'round theez partz of Arizona.

I'll take a look and let you know what I find.

So ......have you found any reason why the motor did the 1 in million thing?

Apologies, work has been a little crazy and I had to take a trip out to LA for a conference. I don't have access to my bike at the moment but when I pulled the rear plug out it was pretty black and looked like it was running pretty rich. Not great evidence for me to why it snapped a rod, but that was the only spark plug that had a ton of carbon build up. I tried taking the head off to get to the valves and see what the piston looks like but I snapped two T-50 bits trying to get the cylinder bolts off. So now I have to order a better bit and get creative with getting those bolts off. Engine does not turn over at all. Wouldn't even budge when trying to turn the crank to TDC. Every thing else on the top end looked completely fine. Transmission is in working order as well.

UPDATE

So after snapping two different torx bits, I ordered a snap on heavy duty removal bit and me and the old man finally got the head off. A lot of carbon build up but to me it looks look all the cylinders were running rich; especially #3. #3 also had some knicks from the intake valve (probably from when the rod snapped. But any opinions from looking at this what could of caused the rod to give way?

Pics are ordered Cylinder 3-2-1 for the pistons and valves. Second to last pic is the close up of where the valve hit the piston, last one is the gasket that had a hole in it.

Happy Father's Day!

Thanks for posting.No clues that I can see why the rear rod broke from the top end images.
You say that the crank won't turn at all.Big end bearing seizure (oil supply failure)is the most likely cause IMHO.
If you can reach it then,undo the broken connecting rod cap to confirm.

Took the crank and Pistons out. Bearings didn't look too bad. Definite signs of wear, but nothing pointing to bearing failure. I found some matching etchings on the side of the rod caps and connecting rods. It doesn't look factory. So to me, it seems that someone had this bike apart before and just didn't put it back correctly. Also the previous owner told me the engine only has 50k on it. The west of the engine seems like a lot more than that.

Bearing looks serviceable bore doesn't look that bad. I suspect hydraulic lock, drain and measure the contents of the oil pan.

I already got rid of the oil. Do you think that hole in the head gasket could have leaked some coolant into the cylinder? The block is completely shot. You can see in the photo that the connecting rod that snapped went through wall of the bore.

Also the cylinder #3 had the most wear on the bearing and the dirtiest valves and spark plug. Not sure if that's an indicator of anything.

Martin · « **Reply #66 on:** June 19, 2016, 07:00:02 PM »

What was the condition of the oil, can you remember the level in the container that you drained it into. The damage on the head gasket looks like it was done on removal. Can you see signs of leaking on the gasket, head or block. The only time I have seen con rods with that amount of damage was on vehicles that had been submerged in water while the engine was going. Big end lube failure causes different damage not evident in your pictures. Have you contacted the previous owner.
Regards Martin.

danpalooza · « **Reply #67 on:** June 19, 2016, 07:21:57 PM »

Oil was a little dirty. Not terrible though. Didn't notice any leaking on the head or block. And I definitely wasn't near any water lol. I haven't contacted the previous owner. I feel like he's just going to give me the run around.

Martin · « **Reply #68 on:** June 19, 2016, 07:39:40 PM »

Can you take pictures of the head gasket both sides of the offending cylinder. While it is unusual for a leaking head gasket to cause a hydrostatic lock it is possible.
Regards Martin.

The Dude · « **Reply #69 on:** June 19, 2016, 07:49:46 PM »

I can only see the first and last images.The first image shows the con rod(big end) shell significantly worn.I guess that journal isn't blue,is it?The main bearing shells are not.Not definitive proof of cause though.Bummer!I would contact the previous owner and.......
ALL THE BEST.

jjs1234 · « **Reply #70 on:** June 19, 2016, 09:30:20 PM »

Could just be a bad batch of steel that the rod was made out of... I suspect that if the cause it's not evident, then it will remain a mystery

Just got back from picking up my two gold crash bar bolts from the local BMW wrecker, who has been working on K's & R's for 30 years +. I asked if he had heard of one bending and breaking a con rod, his answer was never. He has seen a couple do big ends from lack of oil, but even then they have never thrown a rod. I asked about if a blown head gasket could have done it, his answer highly unlikely. He said it might have been apart and assembled with damaged parts, but I can't see how. He did say that given the Bricks reputation you were highly unlucky, if that is any consolation.
Regards a perplexed Martin.

danpalooza · « **Reply #72 on:** June 19, 2016, 11:16:14 PM »

We may never know what the actual cause is. I'm going with my gut and thinking the previous owner tore it apart and did a hack job with re-assembly. Those etchings on the pistons point to that. Nothing else to do but move on and buy a new motor for the bike. Shame it happened but it was a good chance to get to know the bike inside and out. Appreciate all the help from everyone. Hopefully in a few months I will be posting build progress photos of the bike coming back together. Thanks again!

Take the motor apart and sell it's parts. Given enough time you'll likely make 2x back what you paid for new/used
