999 What Have I Done?

Well, did you get the bolt out???

 

I thought that, as the bike when ridden free shows 70 degrees but then I noticed that the 'normal' temp. on my BMW is 100 degrees... :/

 

Mine when running free sits about 68 in this weather other dukes I have had were the same and in summer avg temp 85/90 till you start hitting thick traffic and stop starting then it happily soars to over 100 before fan engages

 

When the fan engages, does that then control the engine temp because on my 999, the fans cut in but don't really seem so very effective.
Other Dukes I've had, had no temp. gauge...

Yes when fan cuts in shortly after you see a drop in temperature on the gauge

 

As one might expect.

Doesn't seem to happen with my 999 though. I suspected low coolant level when I first got it but no.

Will have to try cleaning the radiator where the fans are but the crazy thing is that all is fine until I hit stop-start traffic, the fans cut in but seem totally ineffective. I tried looking for uprated fans but none seem to exist for the 999. You can get different, more effective blades for a 916.

 

Seems strange but out of curiosity when the fans cut in does the temp still rise if not then the fans are doing something. Next time it happens if you can pull over and hit the kill switch so the ignition is still on and watch the gauge the temp should drop fairl quickly if it does it's all good if it doesn't it may be a faulty sensor. Records the rise but has trouble recording the decrease until the bike has been rested / parked and ignition turned off so it resets itself.

 

I tend to try to avoid the situation as much as I can now but the fans seem to have little effect. The temperature just seems to keep climbing. Of course it may well be that it would climb a lot faster without the fans.
One would hope for the situation you have, that the temperature rises, then the fans cut in and control it.
I did start a thread a while ago, titled 'How Hot is Too Hot?' and I don't seem to be alone by any means.

 

Is it just the older models? I've had the 848 Std & 848 Evo and 848 Streetfighter and the 899 all of them have been fine and my 1199 is ok

I did post it in the 749/999 section...

Yesterday I put some Suzuki plates in my clutch, having rubbed in lithium grease, removed the excess and cooked in the oven at 200c until the smoke stopped.
I needed to run the engine to check the action, so let it run until the fans cut in and in that ambient temperature, the fans did their job and controlled the temperature nicely at between 100 and 105c.
So they can work properly!
Maybe if I can get the rad clean enough so it flows air that much better, they can be persuaded to do the same at Summer temperatures.

 

I'm at my dealers now and just enquired and they said when your going along at slow speed you are putting more load on it so it may continue to rise. He couldn't remember if they are fitted with 1 or 2 fans. If it's 2 fan 1 cuts in first and if temp climbs over the next threshold 2nd fan kicks in which should stabilise. Most Ducs will run around the 105 mark in mid summer though

 

It's got 2 fans that cut in sequentially.
Although they controlled it beautifully in yesterday's winter temperatures, they don't in Summer traffic.
Free riding even in Summer gives 70 degrees consistently. It's only when you slow down that the temperature rises above that.

Thanks for enquiring!!

 

All my Ducs have given me 85 ish in summer under normal riding conditions. In traffic 100 plus I think yours is fine mate

 

I thought the torx bit should do the trick, it didn't seem right to junk a whole battery box for the sake of one duff allen bolt.
I don't know too much about electrickery but I don't see why reversing the current through a solenoid, which is basically an electromagnet, should kill it unless there is some other more sensitive component attached to it.
Should be a cheap item though, as I'm sure Ducati will have used a readily available one, so if you remove it and check for manufacturer and serial number, I reckon you'll find easily enough it on the net, if not at your local motor factor.
