Question about 1998 Honda XR 250 R
Sounds like one of two possible problems.
1.) You have overfilled the oil level.
2.) You have a faulty oil pump.
The 98 xr250 is a dry sump model and the oil pump, pumps oil back to the frame/tank (oil in frame).If you have too much oil in your system the oil tank overflows back into the engine the excess oil can affect the internal pressure in the engine this can cause some of the excess to be vented through the crank case breather. A more severe and urgent problem could be a failure of the oil pump to return oil to the tank , this could lead to severe engine damage as your oil system could be starved. Firstly drain all your oil and measure what comes out , should be no more than 1.4 litres, if you have more you have found the problem !! If the amount of oil is correct, then i am afraid you will have to open the engine and have the oil pump / lubrication system examined / replaced by a professional.
Hope this helps
