Who knew Ducatis won't last 5 seconds at top speed?
 
I've blown another engine up. I am getting good at this! All in good fun, but kinda expensive.

Well now that certainly does suck.

pete3799 07-12-2013 04:38 PM

looks like a long walk too.

Baz 07-12-2013 04:38 PM

How did she blow, Richard?

Since I know next to nothing about motorcycles, this may be a stupid question; if you have an idea what the RPM's were at the time of failure, how about installing a rev limiter and set it for 500 RPM below that?

Bill Douglas 07-12-2013 04:46 PM

Any sort of failure at full speed is very dangerous - especially Montana? speeds.

AFC-911 07-12-2013 04:58 PM

Dang! That sucks donkey balls.

What's the top speed on those things?

Don Plumley 07-12-2013 05:03 PM

Ouch. Glad that dripping oil didn't cause a worse problem at top speed...

According to Duc engineers the engines dont have a redline because of the engine design.

Apparently they were drinking the day they decided that. LOL

I almost bought a hyper-retard...glad I didnt.

Warranty probably doesnt cover that huh...

flatbutt 07-12-2013 05:19 PM

that truly sucks. My Monster has a rev limiter. Did you reflash the ECU?

motion 07-12-2013 05:28 PM

I'm sure it has a rev-limiter, but I wasn't into it in 6th gear. That would be pretty tough to do. Can't really disclose speed :D

So I now have a large hole in the case behind the starter motor. Looks like a rod broke. No warning at all... no tightening, no red lights on the computer, nothing, just Bang! Was riding with a buddy so I only had a 2 hour sit-down in the middle of nowhere Wyoming while he got the truck and trailer.

Its out of warranty, so I'll be shopping for a new motor. Not worth the labor costs to rebuild this one.

I would think that oil on the rear tires at speed would pucker every bodily orifice in like .002 seconds

Don Ro 07-12-2013 05:41 PM

Phuq me, dude. :eek:

Were you being a "knucklehead"?

motion 07-12-2013 05:43 PM

Yeah, I pulled that clutch in real quick and coasted for like 2 miles without hardly using the brakes trying to get stopped. OK Don, whassat mean?!

Don Ro 07-12-2013 05:43 PM

Hysteresis can strike anytime. Don't blame Ducati.

Don Ro 07-12-2013 05:45 PM

You told us that you act like a "kucklehead" on that rig. 'member? ;)

Don Ro 07-12-2013 05:46 PM

Oh, that word. Hysteresis = metal fatigue.

Flieger 07-12-2013 05:53 PM

Fatigue is more of a science than that. And hysteresis is not a synonym for metal fatigue if that is what you are saying. Plastic deformation is a sort of hysteresis.

Don Ro 07-12-2013 06:00 PM

I'm being liberal (did I just spell that word?) w/the def. Relax. ;)
.
BTW, Richard, I feel for your disappointment and inconvenience...I do.

MMARSH 07-12-2013 10:35 PM

That sucks...I would be pissed if that happened to my Paul Smart.

Hysteresis occurs in ferromagnetic materials and ferroelectric materials, as well as in the deformation of some materials (such as rubber bands and shape-memory alloys) in response to a varying force. In natural systems hysteresis is often associated with irreversible thermodynamic change. Many artificial systems are designed to have hysteresis: for example, in thermostats and Schmitt triggers, hysteresis is produced by positive feedback to avoid unwanted rapid switching. Hysteresis has been identified in many other fields, including economics and biology.
