I have a problem that is yet to be solved. My 98 WR400 is leaking engine oil. Its coming mostly from near the swingarm area. Its also showing up in my airbox breather tube. Its making my rear brake pads/rotors useless, not to mention my rear wheels/underside of my rear fender is practically covered with oil. At first i assumed it was access engine oil when i had my oil changed. Then i had the bike washed down and all was fine and i rode as per normal. Now its back and worse than ever. I checked the oil now and its at the halfway mark. Thats when hot. Any ideas?
