What causes low oil pressure on Harley Davidson?
A low oil pressure warning can be triggered by several conditions within your motorcycle’s lubrication system, but not all of them are cause for alarm. This first thing to check is the oil level in the oil tank; an insufficient oil supply reduces the amount of oil circulating throughout the engine.
How does the oil pressure switch work on a Harley Davidson?
How the Switch Works. On a stopped engine, the oil switch contacts are held firmly together, which illuminates the low oil pressure light on the motorcycle’s instrument cluster. As the engine powers up, the oil pump pressurizes the engine oil and forces the switch’s movable contact away from the fixed contact.
How do you change oil on a Harley Davidson?
A special socket is available from Harley-Davidson for removal and replacement, but an adjustable set of locking pliers can be used in a pinch. Once the old switch is removed, screw the new switch into place and tighten it from 96 to 120 inch-pounds with a torque wrench.
What should oil pressure be on a Twin Cam 88?
Once it is warmed up and under load it shows 20 psi. and it has gone to 5-10 psi and come back up again. At idle it shows 0 psi. Is this something I should be worried about or is it normal for a Twin Cam 88. If you could shed any light on this matter I would greatly appreciate it. Those oil pressure numbers are typical for your m/c.

What should oil pressure be at 70 mph?
70 mph is cruising speed on most roads in Texas. The psi is about 28 at that speed after about 30 min on the road. The manual says that the pressure is supposed to be 32 psi with oil temp @ 230 deg. f. @2000 rpm (55 mph).
What should the oil temp be on a Harley Davidson?
One of my bikes is a 2002 FLHT, all bore 107″ built motor (124TQ/110HP). I run a Jagg low mount 10 row oil cooler and even now, in the mid 90s, oil temp rarely sees 220*. Your oil temps may see 230* or even 250* but that would not change your oil pressure which is not a function of the oil temperature.
