Recommended Posts

hey guys, my brother isnt too sure how much oil to put in his 03 450exc. obviously dont have a manual.

Im assuming that it shares the clutch + engine oil, so my guess is around 1.5L but just wanted to make sure.

Just a note,,, I have the same bike and 1.2l of oil will NOT register in the sight glass. I can't even see it in the bottom of the glass. SO IGNORE THE GLASS IF THIS HAPPENS AND DO NOT KEEP ADDING OIL TILL YOU SEE IT IN THE SIGHTGLASS. Add 1.2 liter if you are changing the filters, and add 1L if you are keeping the old filters in there.

Yes the sightglass is for checking oil level, but on some of the rfs motors it is hardly accurate. On my 03, In order to see oil in the middle of the glass (as stated in the manual) the engine is way overfilled. It has to do with the way the engine is setup. With the correct 1.2 l of oil, I can barely see the oil in the bottom of the glass when warm. When running, I can see oil flowing in the glass. Just a strange KTM thing
