    Thanks. I've acutally found that response common amoung harley owners now that i've ask around.

    There seems to be a clattering or knocking in my left ear. I don't hear in in my right ear cause of the pipes. Is that common too? One of the guys that's worked on it says if you don't want to hear a noisy engine get louder pipes.

    All I know is it doesn't run right and I can't seem to find anyone who will fix it.

Everyone has oil in their airfilters. Harleys are engineered to vent the crankcase thru the carberator. Some oil will get into the filter. There is nothing wrong and thats not whats causing your bike to run ruff unless u have a paper filter thats clogged with oil, in which case I would recommend replacing it with an after market filter that is designed to be oiled like from K & N which are washable and reusable .

    You might be hearing noise from the primary ( which is on the left) and you shouldnt. The first thing I would do is buy a service manual for your model, if you want to do the work yourself. Fouled or cracked plugs will commonly cause a bike to run rough, and those are easy and inexpensive to check. I would also check the primary for fluid. Very easy to do as well.

Chosing Automobile Engine Oil

There are many types of oil on the market from many different makers and each will claim to be the best oil for your car. They'll claim to have the best year-round protection even when they don't know where you live. As engine technology improves, perhaps the oils will improve too. Until then, here is this...

When chosing oil for any type of engine, the important thing to consider is the thickness of the oil which is identified by the oil's "weight.". The higher the weight - the thicker the oil. Got it?

Engine oil serves two functions. It lubricates the moving parts, and it helps keep the engine from overheating by reducing friction between those moving parts. When you pour oil in your engine, it drains right down to the bottom and settles in the oil pan. When you start your engine, that oil is basically splashed around to coat whatever is near.

Oil behaves like pancake syrup. When it's warm, it's thin and runny. When it's at room temperature, it's thick and not quite as tasty. A thin oil (low weight) it will drip back down into the pan more quickly than a thick oil and therefore won't cling to those moving parts quite as long. The hotter the engine gets, the thinner the oil gets. So, you need an oil that will be as thick as your engine can handle so that as it heats, it won't become too thin. If you live in a climate that is hot year-round, use a thick, high-weight oil.

Some will say that if the oil is too think, it won't run down fast enough to carry away the heat from the engine. Yes, that is true. However, oil is not designed to cool the engine. Oil is designed to prevent heat buildup. There is a big difference. Oil is not a remedy for heat, it is a prevention of heat.

Your car's engine does not get hot from the small explosions of gas burning inside the engine. That heat is expelled with the exhaust air. Your car's engine gets hot from the heat that is generated by the friction of the moving parts within. If you reduce the friction, then you reduce the amount of heat that is generated. That is what oil does. Therefore, it needs to coat, stick and stay put.

1972 shovelhead engine needs spark plugs and oil!

I have a 75 FLH and I use the Bosch Platinum WR8DP if you have the long plug if you have the short one it is W8AP, they are an exelent plug. As for the oil I use Rev-Tech grade 60 but you should stick with one kind of oil and for a FLH it is 4 qts.

1 qt oil every 1000 miles

kev, check you have the right level on your dip stick, oil must be on upper mark when donk cold.also ensure you are running the correct oil weight for your donk.
engine may be running hot; which means one way oil can go missing is its being burnt.
also check your primary drive,clutch oil level ,not sure as i have 80cube evo, but you may find your oil in there due to bad oil seal internally. im no expert but these may be of help.

98 fatboy engine noise.

Harley's do run hot, anywhere from 220 to 240 normally, and a little hotter this time of year. I suggest running a straight weight oil, and a little heavier weight in the summer. I use Valvoline VR-1 30 weight most of the year, and 50 or 60 weight in the hot summer, and I use Lucas 20w50 primary/trans for the primary and tranny. I don't bother with the extremely high prices of the HD oils. For the whining noise, you need to determine which side of the engine it's coming from. Whining will almost always be in the bottom end. There's nothing in the top end that should whine, and if there is whining from the top, it's usually an air leak around the carb. Start by checking the fluid levels in the tranny, and primary. These are the two most common areas to pick up a whining noise. If it's coming from the left, it's going to be in the primary, and usually this is caused by low fluid levels. From the right, it's going to be either the tranny, low fluid, or the oil pump. The oil pump is a gear type system. If you're running a light weight oil, say a 10w40 or HD 20w50, when the engine heats up and the oil thins, it can cause the oil pump gears to whine a bit, especially in the summer heat. So, check the fluid levels, if they check good, then change the oil, since the summer is coming to an end, go with a straight 30 weight. This should clear up the whining noise. If it doesn't, get back to me with the exact location the noise is coming from, and we'll go to the next level of diagnosing the whine, but I believe that this will cure it.

Do new 1450cc harley davidson engines use same oils in engine and transmission ?

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

Oil cap blasting off

Your crankcase is not breathing right. Re-Check your lines going into the air filter back plate, make sure the lines are not kinked in any way. Also make sure the lines are not dry rotted.
