there is an oil tank in front of the engine. there is a bolt on the very bottom of the tank. i think the bolt is a 14mm. also, there is a bolt by the shifter. i think this one is a 12mm. you will need to remove both of them to drail the oil. one drains the engine and the other drains the oil tank. the filter is on the right side of the bike. there is two 8mm screws holding the filter cover on.
