Running hot

After reading this post I have been making some calls.  As a matter of fact I just got off the phone with a Duc dealer in CA.  I asked them about the temp readings/bars and told them that I am normally in the 3-4 bar range and they said "you are in there, NO worries".  They also said that the bike will shut itself off before it causes any damage.  If that is true, fine. 

I am a little confused on the temp sensor location.  Is it only on the vert cyl or is it a combination of this and oil temp?  IDK.  The manual says that the Bar range is an indication of OIL TEMP.  But, the average joe (me) wouldn't know if that is truth or if they use the vert cyl for the temp reading.  As long as I am in the range (yet to be specified) that is safe.

When I get my hands on a 696, I'll try to get temp readings with an IR gun, comparing the sensor mount region with the sump area.

I can't believe that it's really reading oil temp, as when *that* gets above 300 degF the oil starts deteriorating rapidly.

That's the thing that gets me, if over 300 is so bad, then why would 300 be less than halfway up the gauge?  Seems as though four bars is mid-level, five is slightly above (understandable since i'm running pretty hard, pushing a lot of wind at ~100mph) i'd imagine 6 to be "watch yourself", and 7 to be "you're hot, cool it off."

Speeddog, thanks for your effort in this thread.  I know that I really appreciate it. 

If I may ask as a noob here, where did you find that the temp "pick up" is on the very cyl?  I'm not questioning your knowledge, but just verifying.  Also, do you know where one can score a service manual for the 696?

As the OP i also appreciate his insight immensely.

The Manual is available online through the Ducati site as a pdf.  The link was posted in a thread not long after the bike came out.

Just downloaded.  Thanks.

You can download the parts catalogue from ducati.com as well, it's very helpful for understanding how the bike is put together.
That's how I got the info on where the temp sensor was.

As far as a real service manual, AFAIK your dealer is going to be the only source.

Some of the very basic engine stuff would be covered by the DesmoTimes 2-valve bike manual, but there's a good bit of stuff that's different on the 696 engine vs. the previous air-cooled Ducs.

All of the chassis and bodywork stuff is totally new to the Monster line, though it does have some similarities to the MultiStrada (that's not necessarily good, from a service standpoint  :( ).

Hey, I have one quick question for you.  If you look at the parts manual and go to drawing 10, look at part number 43.  It is listed as a "sensor", but what is that thing sensing?

Speeddog

Pretty sure that's the ignition trigger.

zedsaid is wrong with those temperatures.  Look in the manual.

I got them from the manual.  When i say "three bars" it is "status 4"  and the Fahrenheit temps were converted via http://www.wbuf.noaa.gov/tempfc.htm

His posts match my copy of the manual.

Well, over the past few days I have had several conversations with DNA about this issue.  Again, my bike seems to be running fairly cool (in comparison), but none the less.  DNA told me that the temp readings are an actual oil temp.  I questioned this based on the temp sensor location, but they insisted that the sensor on the vert cyl head PLUS another one gave you the oil temp.  Really?  Whatever. 

They told me that I should just keep an eye on the temp and if I am getting too high that I should give it a rest.  Now, I understand that this is  an aircooled motorcycle, but when your scale has 8 bars and you are running slightly over half I find it difficult to believe that you are running WAY TO HOT.  Nice graduation!! 

Anyway, I think we are still at square one on this as it seemed that DNA is learning as we are.  So, keep up the investigation and lets get this figured out.  By the way, I have another email in to them about oil coolers as the mounting brackets are on the 696.  There just isnt a kit specific to this model.  Anyone know of a kit that WOULD FIT NO PROBLEM???  I will be putting an oil cooler on my bike before next summer.

He didn't happen to mention what "too high" is?

Keep in mind, folks, first, we are talking oil temperature, not water temperature.  Also, as Speeddog said, the sending unit is high on the vertical cylinder.  Assuming the sensor is in an oil passage the oil would be hotter than in the sump, particularly if it is in a return passage.  Most likely, the temperature of the metal of the vertical cylinder would also affect the reading.
