well i changed the oil in it and when i went to go ride on the friday, the oil was changed on wed. i noticed a bit of oil on the shed foor. i thought it may have been the lift over oil dripping of the skid plate. so i drove threw water and mud and then parked it till the next weekend. thats when the problem occured. i didnt notice the huge puddle of oil on the floor until i got back on sunday. so when i checked the bike and thats when i found that the drain plug i took out was fine but the plug thats behind it wasn't even there.:???: I didnt even take it out or even touch it. how in the hell does it come out? so i put a new plug in and oil but now when i start it i get a buzzing/ tickng noise that seems louder on the clutch side. i dont know how long the oil was out of it but i droce it probably 2-3km until i noticed the big puddle. thanks
