Ok so I bought this 98 xr400r and I did a filter and oil change. The problem I have is when I went to remove the frame oil drain bolt it was striped. Well not a big deal...I got it out but only about a half a cup of oil came out! When I pulled the main plug the rest of the oil came out ( the appropriate amount) so I also changed the filter and then put in just under 2 Q of oil like the book calls for. Now I have put about 10 miles on it riding it around the hood ( I am sure this is make my neighbors happy,DG exhaust and xr spark arrestor) while checking the oil hot and level It does not even register!.what's up with that. I has not leaked out I know this for a fact. .
