Ducati broke down, engine warning light on

I'd get a thermostat that triggered the fan at a lower temperature.

But that's just me being lazy, or not wanting my engine to overheat due to crappy design. :teeth

You could always just add a switch that allows you to turn on the fan whenever you want it on. Some people used to do that with the Ducati ST2 or ST4 (can't remember which). But when I had the ST2 I'm not sure the fan ever went on and it never overheated. The 888 Superbike would get hot real fast in any stop and go traffic, though.
 
Gee, big CC race bikes in stopped traffic in hot weather getting hot. Whoda thunk?

Sucks to all that manufacturers put plates on them and try to pass them.off as street bikes. And sorry to OP for the Duc problems, but I really don't know how or why so many people ride Superbikes on city streets.

But the Duc-Duc-Duc sound, the light weight, the raw, "character" of the engine, the DNA - how can you not handle a little bit of punishment for such a thrill.

Nevermind, I like redheads too.

I'm out of town until sunday so won't get it in the shop until maybe next wed to find out what the issue is.
There was a blast of heat from the engine just before it screwed up so it could be catastrophic, which would suck. Other than that cool bike though :)
 
Back home today and got my first chance to look over the bike. There's no coolant showing in the overflow container. That might explain the extra blast of heat I felt seconds before the warning light and the breakdown.

I check oil every time I ride and check coolant once a week. coolant was low a month ago and I had the dealer top it up under warranty since it was in the shop then for a warranty repair on a leaky thermostat.
I didn't see any coolant in the oil or any leaking on the floor after its week of being not touched.

Is there a pressure release valve or likely it simply leaked out?

I have learned to shut off my Tuono when I am stopped at a long light. The temp eventually climbs to 239 F, which is when I start getting warnings. A guy I know has a 1299 Panigale and he does the same thing - shuts the engine off at lights. These bikes are not made for stop and go traffic in mild to hot weathers.

I do turn off the engine in traffic when I can. Always did that.

You guys do realize that shutting your bike off only makes the engine hotter right?

I'd suggest a complete flush of the coolant. Take the radiator off and clean it out. Over time gunk gets in and fill the bottom. I'm betting the fan is at the bottom and not providing the best cooling since the fluid isn't actually passing over the fan.

That blast of hot air should mean your fan is working. When my bike's fan turns on my left leg cooks.

That's something I've have wondered about in the past also, however when the temperature gauge continues to rise and I don't hear a fan cut in it seems shutting it down is the best way to drop the temperature.
As long as there's water where it should be and not fire in the cylinders any heat increase should be short lived.

right, how would stopping the explosions make things hotter?

another (more fun) way to drop the temperature is to get up to speed

Wow you left out pretty much the only relevant fact from your initial post.

Thermostat was replaced with a new one 2 months ago.

Getting up to speed was not an option, unless I rode down the sidewalk.
 
Bumped this into Garage since it appears to be a typical repair question and not a I'm-stranded situation. Good luck getting it fixed!
 
Turns out it was a loose TPS sensor plug that left me stranded on the side of the road for hours :rolleyes
 
You'd better submit that TPS report soonest or you'll be coming in on the weekend.
 
Not yours, it was purchased with company funds. Suck it up, four-eyes.

This. Thermodynamics says "There is no such thing as a free lunch". Maybe petroleum companies are threatened by this new form of energy and don't want word to get out. :teeth

The phenomenon is known as "heat soak" and occurs when the engine is turned off. The combustion process is stopped which terminates the momentum of the crankshaft, which stops the turning of the water pump and/or stops the electric water pump. Since the coolant is no longer being circulated, the engine block and cylinder temperature increase for a short period of time, say for a minute or so to maybe 8-10. Of course this also depends on ambient air temp, fairing, bodywork surrounding engine, etc.

As a result, the temperature of the engine block transfers the heat to the coolant. The coolant temperature then increases, which in turn increases the pressure inside the coolant system.

Lots of vehicles and some motos have electric fans that remain on after the vehicle has been turned off. This process pulls air across the radiator and circulates air through the engine compartment to reduce "heat soak".

Just my :2cents:2cents (adjusted for inflation) :afm199
