The oil light come on and off all the time I now oil in I chang it Kawasaki 2003 805cc drifter

Well i would say the clutches have sat dry to long. You may change the oil and it solve the problem but more than likely new clutch discs.

Yes. I have a 99 nomad and use valvoline 5w30 full synthetic. 30,000 miles with no problems

I am not positive, but I know the bikes have different frames. As a rule of thumb, Kaw will make slight changes so the parts will not interchange. You can go to ronayers.com and look up the microfiche on both bikes to see if the tank part numbers are the same.

it will come out eventually it is condensation the only other way I have been able to remove it in the past is to drain the oil and take a heat gun or a blow dryer and use it to dry the condensation

Under the bike below the front radiator you shoud see what I think is a 13mm nut place a drain pan below the bike about even with the kickstand and unscrew the bolt and away you go draining the oil. let it run out till nothing comes out and replace the bolt and don't over tighten it but snug it well. then right below the radiator is your oil filter it should be tight but also able to turn it by hand, remove it and replace it. Then on your foot side where your gear shifter is,is where you replace the oil, the sight glass is in the other side below the floor board,there is a high and low mark ....be sure not to over fill dead center should be about right. Run the engine in Nuetral for a minute or so and shut it down and check the level and add accordingly.

Warm the engine to ensure maximum oil drainage. Steady the bike on a stand or secure jack, as close to level as possible. Ensure the availability of a pan that can contain at least three litres of oil, with enough extra room to lift and move the pan. Slide the catch pan under the center of the oil pan, and remove the large oil drain plug from the center of the oil pan. If the catch pan is large enough to reach the oil filter, loosen the filter at the same time to allow better flow. Once the oil has finished draining from the plug hole, replace the plug and torque to setting. Remove the oil filter. Apply a film of oil to the gasket of a new filter, and install the new filter as per the manufacturer recommend tightness as listed on the package. Remove the oil filler plug on the left side of the engine case and pour 3 litres of 10W40 or 20W50 (depending on climate). Replace the oil filler plug.
