If you indeed do not have any oil pressure, our engine will rattle very badly. It'll sound like tin can full of rocks because your lifters are hydraulic. If you've installed a gauge on your bike and it's showing no oil pressure, this is not unusual.

A Harley engine is a high volume low pressure system. The reason is that the engine is a roller bearing engine. Unlike an engine built with "shell type babbit bearings", you Harley will not hold a lot of oil pressure, especially when it's hot. The oil pressure switch on the older bikes used to turn off with only four pounds of oil pressure. You might can screw your oil pressure gauge out and spin the engine over, not start it, but just spin it over for a few seconds to see if oil pumps out of the pump.

If you're still not sure, trailer your bike to the nearest dealer and let them investigate the problem.

Good Luck
Steve

How much pis in front forks hd flhr road king


15 psi is the Factory recommended pressure.
Try it. If it feels too spongy pump it up to 18-20. If you need more give it a bit more but never go over 25 psi!
If it feels to harsh drop the pressure to about 10 psi.


Worth checking your fork oil too. You really need clean new oil every 10,000 kilometres (6,000 miles).

Oil light flickers at cruise 2006 road king


Hi Anonymous, if your oil pressure gauge is acting eratic or your oil pressure light stays on you could have a faulty sending unit, gauge or air in the system or a restricted oil filter, start by checking oil level in tank and make sure it is between the add and full mark. With engine at normal operating temperature 180-230 degrees and the use of a 10 micron synthetic media oil filter, oil pressure will be 30-38 psi at 2,000 RPM and 3-5 psi. at idle. The oil pressure light is designed to come on at 2 psi. or less. To accurately test oil pressure remove oil pressure sending unit and install known good oil pressure gauge that reads 0-50, there might possibly be some plumbing required for hard to access points. If you are out in the middle of nowhere and there is no cell phone service and your oil pressure gauge isn't working and your oil pressure light is burned out, despair not, you still have one last line of defense left HYDRAULIC LIFTERS, as long as those tireless workers are quiet, you have oil pressure, maybe not much, but enough to get you down the road at a slow to moderate speed using the least amount of RPMS as necessary. Good luck and have nice day.

OIL LEAKING FROM THE BOTTOM OF THE CRANKCASE ON MY 2002 ROAD KING


Bummer on the oil leak. Typically the oil is not from the crankcase, but from some connection, somewhere and leaking down to the bottom of the crank case. Pressure wash completely, run the bike and inspect carefully. Much more common issue is a primary to crankcase seal.

2005 Road King oil light came on this morning when I started it. I turned it off, garaged it and went to work in my truck. Gonna go trouble shoot tonight. its only got 6,400 miles on it. what might it be?


I've heard the Twin Cam oil sensor located in the front of the cam chest is prone to giving problems. Start the engine and listen. If the engine sounds normal, check to see if you can determine oil flow back to the oil tank. I'm pretty sure the Road King oil tank is on the bottom of the transmission which is going to make this difficult. But, the fact still remains, if you do not have any oil pressure, your tappets will clatter like hell. It will be obvious that you don't have oil pressure. Check the wire to the sensor on the front of the "nosecone".

Good Luck

I changed the mufflers on my 2006 Road King from stock to Rush mufflers with 2" baffles. I notice that I now have tranny fluid coming from the over flow hose. Difference in back pressure?


The exhaust back pressure won't affect the transmission oil or pressure.
I think it needs investigating and maybe there will be a simple answer.

208 Road King would not start after changing oil filter.... Does it need oil pressure established in order to allow it to spark or start?


yes if it does not have oil pressure it won't start it is a safety device but should prime right away. try removing the filter and see if the gasket surface is dirty, if it is clean it if the gasket is bad buy a new filter. Fill the filter before installing then try it again.
