Was the tail wind 60kph and were your grundies clean?? Probably more drag due to lower pressures on tar seal. I would love to see some correlation between cooler oils and CHT. Might just have to talk to TSV? or put an oil temp guage in. My meat thermometer wont cut it. Tail wind at 40, grundies clean on so still fluffy (more drag), I can't see it having an immediate affect on CHT under load but the block will be acting as a heat sink thus it must draw the temps back quicker if it is cooler. Will try and get some CHT and oil hose temps together, the pattern of substantive cooling is there so it will have a difference in theory.

I think I may need to get an oil temp gauge reading (dipstick cum Oil temp) to complete the analysis.

I have both oil and head temp gauges, can only ready the oil safely when I'm stopped but watch the cylinders as the gauge is on the bars. Interesting I think the LH side runs a little cooler than the left but have to remove the RH wire at the plug to confirm I don't have the wires mixed! Do I need them both, probably not!

I run 2 independant digital guages fitted to under plug sensors. The LHS runs cooler than the RHS.
