My light comes on all the time when really hot. The light trips when under 4 psi. Give it a little bit of throttle and the light will go out. I've got a gauge and the pressure shows real low.I have a 2004 ridgeback and have noticed when the engine is hot and I make a hard stop the oil light will come on for a coulpe of seconds then go out. Does anyone else have this experence? Is it because the oil tank is mounted low andthe oil is sloshing back and forth?
Harley-Davidson Oil Pressure Specs 1940 to 1999 Engines
Cold engine start-up: around 44 psi.
Warm engine at 55 mph and up: 30 to 36 psi.
Warm engine At idle: at least 10 psi.
Keep in mind that the outside temperature will effect oil pressure
In hot weather - thinner oil, less pressure - use a stronger spring
In cooler weather - thicker oil, more pressure - use a weaker spring
Way up in the North your having that much issues regarding oil pressure when its hot?I've got the ERT installed. As the weather gets hottter i will change the spring and i can turn in the top adapter to also increase spring tension. When it is real hot out and driving in the city my light still trips on even with this ERT system. I'm also running Lucas straight 50 oil and my engine is 124".
whats your oil pressure at when cruising per your gauge? What about at idle? Seems odd that running 50 with an oil cooler in Canada is still giving you an oil light. Something seems off....I never had a problem with the oil light until i got to around 2700 miles. I had just changed oil and after that the light started tripping on. Changed the oil sending unit, installed an oil cooler and went to straight 50 oil and installed the ERT system and lite still trips when i drive around the city and it is hot out.
