How do you know if the oil pump is functioning properly....I would hate for the bike to seize from lack of oil.

I will first check the oil level after I warm up the bike.

Others more knowledgeable will chime in but I would make sure that oil is returning to the tank properly.

I don't see puking and my bike is not smoking. Will it cause any harm to the engine and will it eventually release from the crank case breather hose (the one attached to my catch can off the oil pump)? As mentioned previously, I have never seen anything come out of that breather hose.
3 Quarts is plenty in a 4-speed shovelhead... sometimes too much.... Only ever check oil level when Heat soaked... study Dry Sump systems to get the Why of it..

According to the manual, oil level is full when it is 1" from top of the one gal tank. My oil pressure light turns off after start up.

I read somewhere to check the oil return by removing the tank cap while bike is running and look at the oil return inside the tank to see if oil is coming back to tank.....an indication that the oil pump is functional.

Is this correct? Just trying to determine if my oil is circulating properly.

Sorry for my ignorance but where is the oil pump screen....I don't see a reference anywhere.

Pulling the oil tank cap while running is gonna make a quite a mess..Simply turning the engine over is sufficient to see return oil..
note thai I have witnessed the return side having a sheared key [in the pump] that still returns oil by friction o f shaft to gear...but, those same motors sump terribly while running... especially above idle.
Final Note; These dry sump systems are also Not Fussy about oil level... Hell...we run the DragBike on 1 to 1-1/2 Quarts total...and My shovel never complains as long as the Oil is Handily on the Stick!!!
The Oil light is on the feed side...so any oil is going to result in pressure..

I read about dry and wet sump systems and understand the differences and its benefits a little better. I am sure you know dry sumps systems too well being a racer.

Before I suck oil out of the tank....In your statement above, is it supposed to read ".....Only check oil level when heat soaked" or ".....Only never check oil level when heat soaked"?

Will check the return after I get the oil level corrected which I presume is the top line on the dipstick or 1" from the top of the tank..

Also, pm me your name and address and I will send you the toe shifter with pin and the shifter arm if you still want it. My foot rests fine with the heel-toe shifter and I will get used to shifting with the heal...I can always use the toe in the interim.
