Great Forum, enjoyed reading a lot of comments!
I had the engine fiddled a bit (ported head, exhaust cam and a few other bits). It's producing 135C which is 275 degrees Fahrenheit (measured in the sump, have an Oil-Water cooler fitted) during operation.
Note that prior to the "mild tuning" temperature was at 135C without Oil-Water cooler.
The Manufacturar recommends 10w-40 Oil but
I have been told to use 10W-60 because of these high temperatures, however I am aso concerned by the thin oil feeds which go up to the cams.
Which can be seen here:

Does thicker oil realy help in such an engine, considering temperatures ? Or can I easily go back to an 0W-40 Oil (which should help oil climb up the thin pipes easier)
