Oil Temp

[teedee]

Hi,

I've just fitted a dipstick type oil temp gauge to my XL600r fitted with a Dommie engine. I've just run it up a dual carriage way at a constant 70mph 4k revs, the temp gauge went up to 110 deg after about 10 miles at which point i pulled off and slowed down but the temp only dropped to 100 deg, it's cool and overcast weather. Is this normal the engine sounds fine and runs well, just a bit paranoid and wished I’d never fitted it!

Have you checked the accuracy of the gauge?
Boil some water and stick the gauge in it to see if it reads accurately.
If it is accurate then maybe you should consider installing an oil cooler.
Not hard on these bikes, maybe a bit of fettling required but there are lots of threads on it.

In between 100 -110 don’t worry is normal for any engine
could be deferent in depends kind of oil
If go over 120-130 be worry but XR-NX engines works hot, possible to fit an oil cooler..
Anyway engine oil boils even at higher temperatures

I think it's fine.. My XT600 used to regularly run at temperatures of 100-130..

It's absolutely fine for modern oils...

Just been talking about this over on a car site I frequent. The topic came up because someone had much the same concern about his oil temp:

"The temp gauge scale goes to 140 DegC and the needle goes above that when the engine is being used hard"

Main reply was -

"140°C is very high but not critical.
I'm not certain about what "semi-synthetics" are capable of but the problem with mineral oils is that they quickly start to oxidise at about 150°C
Fully synthetics will cope with 150°C OK & take short periods of 165°C before that happens."
