Is there a thermostat in the oil cooling circuit (1150)

[Mad Hatter]

Is there a thermostat in the oil circuit of the 1150GS/GSA? Looking at the parts fiche there doesn’t seem to be one in the cooler, but there is a part in the oil circuit which could act as a thermostat, but it’s purpose isn’t clear, the part is ‘Expanding element (95CEL ) (11411342761)’.

Does anyone know?

My reason for asking was regarding whether it’s possible or not to drain all of the oil from a cold engine

I believe there is, and that’s why you always measure the oil level after leaving it to stand on the sidestand for a while after a run. It lets the oil drain back from the cooler circuit and gives an accurate reading, otherwise you’re left with some in there and get a false low oil level.

That makes sense,thanks

According to realoem, For a 2003 1150 - no thermostat is shown in the oil cooling circuit,

I suspect its the same for the other models -

I think you may be getting your reasoning for it, a bit mixed up with how a water cooling circuit works

It’s easy to say there isn’t one, then explain the need for a 95 Degree Celsius expanding element, (Item 15) which looks like it’s located underneath the oil temp bulb.....nenau

Could item 15 be a pressure release valve ?

Thanks for the sarcastic reply. - I looked on the cooling circuit where i thought logically it would be, clearly i made a mistake

Nice to see the spirit of helpful GS tosserness is still going strong

Rather than have a pop at someone for making a genuine mistake, why didn't you just post the link the the correct page to the op in the first place ? ?

Because the OP was already on the case, part no and everything. He just needed confirmation. You just pitched in with doubt. Quoting the real OEM as your source. Which probably isn’t very helpful.

I was interested to read this. Whilst it's logical that there might be one, in years and years of reading posts here from tossers who have collectively done millions of miles on oil heads, I can't recall anyone reporting issues. So that made me think there wasn't one.

Perhaps they can in fact fail, but fail safe so the bike just takes a little longer to warm up??

 

[Mad Hatter]

Ian Hartley, I’m inclined to agree with you that the expanding capsule must function as a thermostatic valve in the oil circuit. Also agree with the last post that it would be difficult to notice a defective one.

Thanks for all the replies gents. Looks like I need to finish putting the rest of the bike back together so I can run it up to temperature before changing the oil

There are many details on an oilhead that in the longterm probably don't matter...

I seem to remember it was an 1150 change, the 1100 didn't use one. Happy new Year.
