g'day guys just got myself a Yamaha , was great for a week! A lot quicker than my nsr150sp and riding in japan is awesome fun. Was planning on doing a tour west when I ran out of fuel.... Filled it up and then only 1 piston was working!! was wondering what I should look for. Was planning on going top to bottom , fuel tank, lines, spark plugs, carbis, pistons... Anybody ride one of these bad boys?
