i was wondering does it have an over fill? i had put some motorcycle gear oil(about a quart) and when i went ridding that day i noticed quite a large rainbow in the water underneath me lol just trying to see what i was leaking
you shouldn't put a full quart in.....its 650ml or just halfway up the sight glass down by the footpeg on the right side. there's an overflow vent on top of the engine case, that's usually vented under the hood
