Cry Update

Right here's what I've done today.

I cleaned all the oil up that was on the casings, I checked and topped the oil level up (she lost just over 700ml).

I dowsed the engine in talc started her up and waited..........

Here's what happened;



At the rear of the front cylinder





The other side





And the oil pressure switch is damp and oily



I'll be ordering an oil pressure switch, but do you think I'll have to replace the gasket at the bottom where the leak is??

I had similar symptoms to you last year and was convinced the head gasket had gone but it was oil blown through the crankcase breather hose that had run into the bottom of the filter box and run out onto the cylinder head because the drain hose had become detached.

Looked for all the world like a blown cylinder head gasket - I even stopped at a KTM dealer in Germany for a second opinion, and their mechanic - a beautiful little blonde girl with her arm in a plaster cast - agreed.

Checked the pipe Pete and all is good, it is leaking from the bottom of the cylinder.

Hi Dee Gee

Your Oil pressure switch is leaking from the sealing washer, the oil is then running down the barrell .
The new switch will come with a new sealing washer.
I would still check your Breather pipe as a precaution.

which breather pipe do you mean Rick? I've checked the long one which comes up from the left engine casing and fastens to the top front of the air box. I think there's a non return valve in this one???

Touch wood it's sorted.

New oil pressure sensor switch as most of you correctly diagnosed. Just buttoned her back up and done approx 15 miles and so far so good!

Thanks for all your help and advice

Gaskets leaking???

I do not recall any oil leaks developing on cylinder gaskets.
All I can recall are either oil leaking from the airbox or the side triangular airbox doors, or from this damned oil pressure sender. Cheers.

Cheers Gefr your wisdom is always appreciated, : it just looked as though it was seeping from the bottom of the cylinder, but you're probably right I guess it just ran down and around the cylinder, couldn't really see with the tanks on.

Just hope she's ok for the trip next month. Fingers crossed

This just happened to me last Thursday. Exact same leak pattern etc.


Symptoms were upon start-up the oil pressure light progressively look longer and longer to go out.

Normal clatter went away in a second it's just the light continued to glow.



Cheers to this place for the information and knowledge it holds.

Hi Guys

I am new to the forum so drinks on me blar blar blar

Just being reading this thread and i am currently having the same problem with my 950, i have replaced the pressure switch but it did not stop the leak the cylinder nuts have been done too so i am not sure what to do next! I think the valve on the breather pipe is worth a bash tho!

Did you replace the washer that goes with the oil switch? It has a separate part number.
