Items needed: 1.3 quarts of good quality 10-40w motorcycle engine oil, oil filter, flat head screwdriver, funnel, 10 and 14mm socket wrenches.
BEFORE YOU START – WARM THE ENGINE!
Step 1 – Open the oil filler cap on the right side of the engine on the top of the clutch cover.
Requires a flat head screwdriver.
Step 2 – Using a 14mm socket wrench unscrew the drain-plug on the bottom of the engine.
make sure that you have something to drain it into. They sell pretty neat pans at wal-mart and auto-zone.
Step 3 – Use a 10mm socket wrench or t-handle to loosen the smaller drain-plug located not far from the bigger one.
Step 4 – Replace both drain plugs.
Step 5 – Gently place your kx250f on the ground with the clutch cover or right side facing up.
Step 6 – loosen the oil filter cover by unscrewing the two 10mm screws.
Step 7 – Remove the oil filter cover cap and using a screw driver pull the oil filter out.
Step 8 – Take a little oil and rub it on the seal of the new oil filter.
Step 9 – Replace filter and cover as well as screws.
Step 10 – Stand bike straight up , use a funnel and pour good quality 10-40w motorcycle engine oil into the engine. We use 1.3 quarts until the window on the clutch cover has oil near the upper measuring line but the exact specs are listed on the side of the engine.
Run the engine and let the oil settle again. Then re-check the level and top off if needed.
