1198 Overheating In Traffic

did the fan cut in mate?? mine usually cuts in at 107c on a hot day.

 

Was the fan cutting in? Should have come on at low 100's from memory, maybe 103? I wouldn't expect it to cut out though unless the heat was just continuing to build.

I would suggest check the fan operation and coolant, maybe even worth getting it bleed through to ensure no air locks.

Finally, make sure the battery is topped up and operating, the stalling maybe could be caused by low voltage or poor charging and then when the fan kicks in and loads the electrical output, perhaps (and a big perhaps) it trips itself up at this point.

I would check things in order, starting with coolant levels and charging at idle

 

I agree with @Phill748 fans come on around 103 & his checks

Not sure if applicable to 1198 but early 1098s had issues with reg/rec overheating and they fitted a shield, which I'm sure will have been done on day one on the 1198

No dash or headlamp flickering? I'd check battery voltage at 2-3k to make sure all is well with the reg/rec (as Phill alluded to as well). Reg/Recs are a well documented weak link on these bikes which is easy but not cheap to fix

 

Ducatis when ridden in our climate on open roads tend to run cool, so when we get into traffic and the temperature gauge starts to climb, we tend to get worried. The fans cut in in the low hundreds for a reason. The oil needs to get hot if it is to boil off any condensation which has found its way into the oil.
If the fans are set at less than boiling point, the water will never boil off and water in the oil is bad news, it causes corrosion and impairs the oil's lubricant properties.
Synthetic oil will take much higher temps than this and the coolant, thanks to the combination of pressurisation and the normal 50/50 ratio of coolant to water, shouldn't boil until it hits something approaching 130c, so anything below 125c shouldn't be any real problem

 

Get the cable kit and strong battery (I favour Yuasa for the moment) and your starting performance will be transformed.
Do it now...

 

That is true i have had starting problems even with new sh.. ty battery.. replaced batt for yuasa added second ground cable from batt negative to starter bolt and never worried again. Bike stood all winter in garage and starts up no probs.
High temp makes it running a bit poorer and sometimes cuts off i have been worried first couple of times but now start up again and go. I think it happens less often after tb balancing and mixture trimming with ducati diag.

 

What do you call high temperature?

 

I would say going to 104 in traffic in the climate as it is now should take quite a while, i.e a good 10 mins into traffic? also, you would have felt the fans kick in because you will feel the heat coming onto your leg.

Reg/Rec - basically as a bike revs the alternator creates increasing amounts of power back into the battery, it 'regulates' this and ensures that the battery charges by putting around 14.3v steady into the battery and no more. (I am not an electrical expert so please everyone just take this as general advise as per my knowledge).

You can check the Voltage on the dash, there is a mode you can flick into and watch it as you rev the bike.

Anyway, my starting point would be coolant levels and condition and also actually strangely the mapping of the bike, as with the aftermarket custom map my 848 Evo did run a little cooler.

At this time of year I would expect the bike in the high 60's degree in free flowing 50+MPH speed limits, and into the high 80's in low traffic, I have had the 848 and the 899 and they are similar in that they run much cooler than the jap stuff out in free air but do get hot in traffic.

 

What pipes and ecu do you have mate?

 

That sounds pretty healthy. Cutting out isn't of course...

 

I mean 105celsius and higher

 

That is the level at which the fans cut in, so is getting hot certainly but I would contend that it's not actually starting to overheat until it hits 120c or more and 130 is when you need to really worry because the coolant will then boil.

 

@Seech have you actually tried starting the bike and let it sit for 10 minutes or so to warm up

Keep you eye on the water temp and you can usually see the fans through the cut out in the fairing side, when it get to about 105 C the fans should run, if not then let the bike cool and stick your finger in and try to turn the fans with your finger, they should be free and spin easily.
If they are not free as its newish (to you) I'd get the dealer to sort it, or you can whip off the fairings and look into it
If they are free to turn but not going on at 105C the most likely culprit is a fuse, fuse 7 on the fusebox and then there is also a relay check both of these are good

A more unlikely scenario but one that happened to me, if they are not filed correctly from the radiator as opposed to header the system sometimes will not circulate properly

Mine was doing similar, due to the wrong map, your's seems ok. What does it say when you turn the bike on, 1198???
