fireblade oil temps
evenin all.....
some advice required...
I have an 893cc MK indy and am seeing some very high oil temp readings whilst on the motorway travelling at anything above 65mph.
Temps generally sit at about 100 degrees at a steady 65 but go up rapidly if the revs/speed increase and have been as high as 130 degrees. Obviously
if i back off,temps fall back to 100. Oil is semi synthetic 10/40 silkoline and is new.
Oil pressure is about 75psi ish at 6500rpm.
Water temps are constant at 80ish degrees.
Is it normal to fit an external oil cooler or is there any known issues with the standard setup?
An ideas appreciated...
Many thanks
jon

No issues, never seen an oil cooler on a blade. They have a built in water/oil cooler behind the oil filter.
What radiator/nose grill etc do yo have and what gauges?

Dont know what make the radiator is...
standard MK nosecone as far as i know?
ETB guages, temp and pressure senders both brand new as is the temp gauge
What sort of temps should i be seeing?

Dont have info to hand but I think 100 is normal 130 ather high.
I rely on std blade gauge so no oil temp, but normally runs low water temp with MK (Polo) rad

Where is your oil sender mounted, a boss in the sump?
The sender relies on a good earth and can easily misread if not earthed properly. The sender will be a single wire sender, therefore earths through
the case where you screw it in.
Could it have been screwed in and sealed with PTFE? The threads are NPTF and so shouldn't need PTFE or similar to seal. If a sealant is used
then this could prevent a good earth connection.
I'm no expert, but I'd expect if you were seeing oil temperatures that high then you'd see a higher water temperature too. That
leads me to believe a misread rather than actually having a high temperature.

water temp sender is the standard blade one, located above the stat housing.
oil temp sender is in the bottom of the sump, no PTFE tape used. Good continuity between engine casings/senders and battery negative/ground?
It has been suggested that an air lock in the water system could be causing an issue with the oil cooler?
Any thoughts before i go ripping it to bits again?

If your water cooling system isn't cooling the engine, then the oil system will have to work harder. (IMHO).
However, if you are getting a steady 80 degrees from your water temp and the oil temps are going up and down, then I'd be looking at the oil
system.
Unless you have reason to suspect the water side of the cooling system?
I'm unfamiliar with the oil / water cooler on the blade, but I'd have a look at it to make sure it was clear of any gunk / blockages.
My ZZR runs a steady 80-85 degrees water temp no matter how I drive. However after 10 laps or about 1/2 hour on the motorway the oil temp gets up to
120 degrees and doesn't move again. If I stop, it cools down quite quickly. I have an air to oil cooler, but it's really old and badly
located, so I'm in the process of fitting a new one in a better position. However, at the back of my mind is a thought that what my temp sender
is reading is not the oil temp, but the block temperature (my sender is fitted in the main oil gallery in the block).
If after I've fitted this new cooler, the gauge still reads 120, then I think what I am seeing is heat soak from the block into the sender. In
which case, I'll relocate the temp sender into the sump and the pressure sender into the main gallery.

Thanks for the reply,
Mine will do the same, temps go up, but do cool down very quickly if i either come to a stop or find slow moving traffic.
My sender is screwed into the sump, so do you think heat soak could be an issue ?

Could be.
My next step after fitting the cooler, is to buy / borrow one of those infrared - laser thermometers and take some direct measurements from the block
/ sump / water and oil pipes.

Edited to say that I can't think of any bikes that come stock from the factory with oil temp gauges, so perhaps it doesn't matter and
it's just us paranoid BEC boys that have a problem!

Be interesting what he has to say.
I havnt been able to drive mine for the last month but from what I recall my water temp was always 80's but would peak upto 120's if I
drove hard but would come down quick.
If in traffic it would sit around 100-110 with the fan running.
I cant remember oil pressure thought tbh

dean,
my water temps are pretty much constant , fan cuts in just below 90 degrees, so temps stay under that.
