    Mitchy123,



    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.

Why wont mower run after being run with too much oil in it


single cylinder four stroke engines and to much oil is a recipe for breaking things internally. Piston comes down tries to compress uncompressible oil and excessive pressure breaks one or more items. If it did run and just stopped without any dramatic bang or clattering of broken parts you may just need to completly drain it, refill to the correct level, replace the spark plug and check the air filter (may have puked up oil and clogged the filter....even laying the mower on the airfilter side will do this.

or

if its a two stroke mower and you put in to much 2 stroke oil. Drain the fuel, remove the spark plug, cover the lead (so you dont ignite fuel with a stray spark), pull the handle a few times to clear out the cylinder. Clean and replace plug, put in correct fuel oil mix, check airfilter is clear and it should live again.

Oil in air cleaner on a harley davidson 2006 883 sportster


Hi Georgianna, oil leaking from your air cleaner is caused by oil carryover from the engine. For what ever reason the breather system is not seperating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more exspensive ones. Start by trying the following:
1. Run your oil level half way between the add and full mark when hot.
2. Run oil breather lines from head into a TEE fitting below carb/induction module then a single line into a mini filter under frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump
5. Upgrade oil pump and cam plate
Good luck and have nice day.

I have 1986 evo 883 sportster, its blowing oil back through the breather hose into the carby filter, the bike has been sitting for a while with the oil drained .....any suggestions would help?


Even though the oil had been drained, this will still happen. The reason is that the oil still left in the engine has had time to run down and puddle in the crankcase. When the engine is restarted, the oil pump cannot pump the oil out of the crankcase fast enough to prevent it from being blown out of the crankcase vent hose. Since the EPA requires that the air from the crankcase vent be "recycled" through the engine and burned, the excess oil is blown into the air filter through the crankcase vent hose. Once the engine is run long enough to clear the excess oil out, it should return to normal. It will clear itself out due to the fact that the scavenger gears in the pump are larger than the feed gears. It pumps out more oil than it pumps in with each revolution of the engine.

Good Luck

I have a 1999 sportster 883 it's leaks oil out


Sounds like you're overfilling the oil tank. Always check the oil with the bike on the stand. There are two marks on the oil dipstick. The upper mark is "FULL HOT" and the lower mark is "FULL COLD". Keep the oil level between the two marks and never "top off" the tank when the engine and oil is cold. As long as you see oil on the dipstick, ride the bike until the engine is at full operating temp and the only add oil if it is below the lower mark. Never fill it to the top mark. Your Sportster holds three quarts of oil that is pumped into the engine and then back out. The 1983-1985 XR1000 Sportsters, the hot rod Harleys as they were called, on held two quarts of oil. I've seen hill climbers that had custom oil tanks on them that only held a pint of oil. As long as you can see oil on that dipstick, you have enough oil. If you're getting so much crankcase blow by that your blowing oil out of the tank breather tube, you need to run a compression or leak down test on the engine to check for ring wear. Also, I've seen bikes do that when the needle and seat in the carb was bad or the accelerator pump diaphragm bad. Smell of the oil. Does it smell like gasoline? If so, you have carburetor problems and gasoline is running into your engine diluting the oil and adding volume to it.

Good Luck

Oil light comes on ,there is oil in res


The first thing to check is the idle speed. Your engine should be idling at about 1000 RPM or so. If it's idling too low, the oil light will flash on and off.

Check the wiring to the oil pressure sending unit or replace the unit. It's located on the underside of the right engine cover just forward of the pump.

Run 20W50 oil in the engine.

Good luck

Where do I put gear oil? I have a 2001 Sportster 883


You add it to the primary case on the left side of the engine. The same oil lubricates the primary and the transmission.

Remove the clutch inspection cover. On the clutch, you will see a dark blue colored steel plate. This is the diaphragm clutch spring. With the bike standing straight up, the oil level should be just to the bottom of this plate. If you add too much oil, the clutch will drag causing a problem with getting the transmission into neutral whent he engine is running. Do not overfill.
