It's all very technical, our temp gauge shows a section at the lower end defining I assume warm and suitable to operate the vehicle. At the other end of the scale the gauge has a redline which designates the unsuitable temperature range to run in. The average temperature in operation, set by factory engineers is the midway mark. The extrapolation from this is it's suitable to run in between the two scales. Then we factor in, worn inlet guides which lean the mixture, a heavy load,a mountain range, perhaps a little blow by,and any other factors of which there are many that influence temperature. I personally would rather run left of centre, on a 28 year old bike guaranteed to be far from the new, within tolerance machine supplied near 3 decades ago. I base my Idea's on living in the tropics, where on other machines in perfect order I have seen oil pressure drop to zero, even with oil coolers fitted. This bike mentioned in spec ran pressure 1 to 9 psi stock. I wonder what the standard oil pressure reading is for the VN?
