leachman38 is infamous around these parts
Default high oil pressure

Recently got my bike back from dealer after having them replace the crank seal. Also all the necessary gaskets associated with the primary all do to oil dumping into primary. Since having it back I have done a 250 mile day and a 20/30 miles around town. I have noticed while running down the highway that my oil pressure gauge is showing just under 60. It will also read the same thing when running at 50mph on a secondary road. When I come to a stop it will go to under 30psi. I am just wondering what everyone thinks. My bike is a 08 ultra with SE 255 cams and about 81500 miles.

Chris & Carrie has a little shameless behaviour in the pastChris & Carrie has a little shameless behaviour in the past

G'day mate, your oil pressure will always dip right down on idle as the oil pump on Harley's is mechanically driven , but I'm thinking that your cruising oil pressure might be a bit high. I think that around 30 to 40 psi at cruising is all good with 50 psi being the highest. There's a heap of things you could check, does your bike have regular oil/filter changes , the type of oil, is it the correct grade? Have your engine compression tested , this can show up engine wear which could pressurise you crank. The oil gauge or sender or the oil pump itself. Having a regular compression test down is a good thing , its like having your blood pressure checked at the doctors When you had the cams done did you upgrade the oil pump ? because that might be a higher pressure pump.
If I die riding at least i'll die free
