This is a common problem. Now the heading says your bike is a 1979 Sportster. Regardless of what it is, there is a crankcase breather that is routed to your air cleaner. This was done to satisfy the EPA regulation that crankcase fumes must be run through the engine to be burned. With the crankcase air come a mist of oil. This oil builds up in the air breather and runs out. You have to clean the air filter out periodically. You can find the crankcase breather hose and re-route it somewhere else so the oil won't go into the air filter.

Good Luck

"Stability Control Fail" light on.

first job is to check the part load and main beather hoses are ok the stability system light may be a false indicator if the engine has stalled best is to get fault codes out of the ecm with a code reader to help but air leaks on the engine inlet side can cause strange/seeming unrelated symptoms

What is due at 25000 miles?

Normally if you have been following your Owners Manual, it would tell you what need to be done every 200 miles (or weekly), 600 miles (or monthly), 2000 miles (or quarterly) and 4000 miles (bi-annually).
Generally, most important is doing oil and filter change every 2000-2500 miles (quatertly) and if you have fuel filter installed to ensure it is clean and free-flowing. Air filter need to be changed depending on your travelling conditions, rule of thumb speaks every year in the spring if your live in a 4 season or every 6 months in a 2 season element weather.Tightening and adjusting all nut, bolts and valve clearances as required, drain beather hose (must be done quarterly), adjust chain-tensioner, clutch, spark plugs gap, inspect brake hydraulics functions, pad thickness and liquids (a good idea is to change brake fluids every year), check electrical systems functions, suspension, wheel-bearings, steering linkages,suspensions, etc. If your bikes shakes at 50 - 60 mph then get your wheels immediately balanced as this will create a bigger headaches if not attended. Good luck and if comment is helpful then return 4 thumbs up.
