Hi Guys. Have a freshly built engine and it is pressurising the pushrod tube covers and pumping the oil out? New springs, new seals, breather timing OK, oil return OK. Slightly high oil tank pressure? Any ideas? Thanks..

Without any real detail about year, filter type or where the oil actually is "in" the carb I will try to answer. Oil can come from a few sources. The first is the breather tubes from the engine. If there is excessive blow-by the pistons, oil will be drawn into the carb through these tubes. There are also rubber check valves on top of the heads that can harden and cause the same issue. The last one is excess oil from a oiled cotton style filter (K&N). Either way, while in the garage, remove the air cleaner but leave the breather tubes connected. Get the motor up to temp and watch the tubes while reving the motor. If you see a heavy oil mist from the tubes perform a leak down check on each cylinder to identify the problem area.
if your worried that oil stopping your motor from turnning that oil is the same as a sitting shovel "sumpping" that oil will blow out your vent a little messy yup but you got a shovelhead still worried loosen your cam chest bolts just enough to seperate cover from case that should drain enough for you to feel comfortable with it
Hi, there. We just finished, yesterday, to fix a Fat Boy/98. We started it up, but the oil does not get the engine. The oil filter was still empty and clean. Why the oil doesnt get to the engine.....
Any adjustments? Oil Pump bad??How come??

try this for your plugs - might give a couple of options. maybe a later one will do?
Amsoil 20w-50? Depends where you are and what you can get. I think there is a rev-tech oil to suit your shovel, but can't remember the spec off hand. Havoline 20w-50? Oil debates seem to rage on forever on most H-D forums around the world. Have found for me the H-D stuff is about the same price as the rest, and just as good/bad as them.
As for quantity, I'm thinking it is about 31/2 to 4 quarts, as you said.
Check these guys out - maybe better answers than mine mate.
Hope this helps you.
It's trans fluid. It came out of the vent tube just above the primary cover on the top cover of the trans. If you look at the tube, the inside will be wet. Run the bike up to operating temp. Check upright and level.
the lifters are hydrulic and require no adjustment unless the pushrods have been swaped out to adjustables, the stock ones are solidlength like a car you need to undo a pushrod cover to see them we would need to know the thread pitch to determin the adjustment if there adjustable check the lifter block screen for trash also
use a good brand of synthetic 20-50 in everything the primary fluid will last around 10,000mi the tranny fluid the same and the engine around 6000mi the tranny takes 3/4qt the pri takes 7/8qt and the engine gets 2 3/4qt check the levels with bike upright check engine oil level after warm up top off as needed
If you have chain Tensioners then you have a Twin cam. This is NOT a job for an amature. Its necessary to take out Push rods which means remove heads or cut your pushrods and reinstall adjustables. You need to take out your cam plate,re align oil pump..Its not a simple job for a novice. If you have noise they have already exploded or are about to. Do not ride your bike..those plastic pieces can get sucked into the oil pump and do major damage. I told that to a customer that was going on a trip he did not heed warning. He got 75 miles they exploded and he bought a new motor.
If you use Harley oil from the dealer, you use 20-50w oil for the engine and they use special formulated lube that you use in both the transmission and primary,Some people do use the same oil in the engine,tranny and primary, I would not recommend it
