Clang, clang lock then smoke

3629 Views 35 Replies 9 Participants Last post by  Tchase
So I was at VIR grand course for the first time this last weekend. I was on lap 2 of the first session when I hear some clanging for about half a second, my wheel locks then smoke every where. From that point on my motor is seized. I can still put it in neutral and clutch in but when I try to start it then it can't even turn the motor over.

I take the lower fairing off and what I see is my sight glass it really fogged/smoked up but I can still tell my oil is almost full. There is oil in my belly plan but not much at all, everything is safety wired so no bolts came loose. It does look like oil coming from one of the seals but again not too much (probably like a few oz).

Of course my warm up and tech inspection revealed no evidence of this was going to happen. The bike ran great in the morning until the second lap.

Thoughts? Guesses on price?

That royally sucks. If it were me, I'd toss the motor and grab one off eBay.
Anyone know of a place to get one? I can't seem to find a used motor anywhere?
The dreaded big end bearing failure?
What bike is it? Especially which year and what was the mileage? Last time service was performed?

If you heard clanging before it failed, then its most likely a top end issue. When bottom ends go, they either give no warning and a rod flies through the side of the crankcase/cylinder or they make noise for a considerable amount of time before ceasing.

Without more information, it's impossible diagnose.
I have an 1198 that recently had a connecting rod failure at Little Talli, motor did not sieze as I shut it down before that happened. I pulled the motor and took it to Matt Carr at Indy Ducati and it is currently being rebuilt with ligter stronger parts and estimate cost is about $5500, that includes blue printed and valve adjustment, new belts and cams degreed. I am sure that a used stock motor would be cheaper but the rebuild will be way more reliable. Just alittle info on the other end of the spectrum. Call them and talk to Steven in service or Matt Carr himself super awesome guys to deal with. Good luck.

Have you checked the belts? Also start looking on ebay...

09 848 8.9k miles
Had my 7500 miles service done 5 months ago at 7200

Reading above I mentioned I didn't hear any noise or get any indication.
Have you taken the belt covers off?
Where is tye when you need him? Like him or not, he seemed to be able to diagnose problems like this.

Never fear Danny!

Huh?

Anyway, no reason to nitpick, just trying to figure out what happened.

848 eh.. hmm, well I too agree that taking the belt covers off first would be a wise idea. If the belts are in good shape, then we can discuss other methods of determining what happened.

Nope but I found a nice hole in the lower front part of the case. I'm guessing the main bearing fragged and one of the rods tried to punch through. Is that a good guess?

Sorry man I'm not trying to be a dick it's just been a rough few days.

Considering you locked up I'm guessing it a lower engine problem. When I lost the top I only felt a clunk and the engines died. Tried restarting for 3 sec and it sounded like a sick dog.

You've got 3 things in my mind you want to sort out.

1. What happened
2. Why did it happen
3. How will you go about getting the bike running.

I'm still not sure on 2 with my bike but I took care of number 3 with an engine replacement.

I pulled my belt covers off and that answered part of number 1 on my bike.

If you are contemplating engine replacement I got a 2008 with 3000 miles for 1650 shipped to my door. I was willing to go to 2k as I think my rebuild will be much higher than that, I'll find out over the winter.

BTW this is the only one I've seen on EBay the last few weeks (I'm always watching)

Huh and there was no over-rev or anything preceding the failure? Usually when the rod breaks away from the crank, its due to complete ceasing of the bottom end.

Maybe it over heated due to an impeller failure?

Now ya got me interested… ;)

Have you guys thought about putting a 1098 or 1198 motor in our frames? I was wondering what would be cheaper and more effective, duc shop big bore kit for our motors or just grabbing a used 1098 1198 motor and shoving it in there. What do you guys think?

Someone on this forum has put a 1098 in an 848, I'm too lazy to search :(

I just couldn't justify the cost of the engine and all the problems putting a larger engine in.
