Harley motorcycles may puke oil due to a few common issues, such as overfilling the oil tank, which can cause excess pressure and lead to oil leaks. A malfunctioning crankcase ventilation system or faulty seals and gaskets can also contribute to oil expulsion. Additionally, riding the motorcycle at high RPMs for extended periods can cause oil to foam and overflow. Regular maintenance is essential to prevent these problems.
there is a check valve in the oil system that is stuck open over filling the oil tank will cause the dipstick to blow out of oiltank
I thought I had high oil pressure, When I would rev the engine the oil pressure would max out on the oil pressure guage. Luckily it just turned out to be loose connections to the oil pressure sensor. I tightened the terminals and the problem went away.
WHAT????
Sunoco, makes Harley Davidson engine oil
where is the oil drain on a 2002 harley softtail
Knowing the year would help answer this better.
how much oil is required to change oil and filter in a 1997 Harley Davidson Sportser
It can happen if bike has not been started for awhile. Oil leaks past check ball in oil pump.
The primary oil does three things. Lube the clutch. Lube the primary chain . And cool the stator. If Harley thought Dextron would do this, they would have recommended the use of it. Keep your Harley a Harley.
I would suggest hard chrome on the oil pan and belt cover. You can chrome most non moving engine parts on a Harley Davidson.
No oil in crankcase in a Harley Big Twin. All FXR's take three quarts in the oil tank.
