I don't know why they tell us to put the oil filter on hand tight and then they go at the factory and install it at 2000' pounds per square inch. Now I spent almost $12000 on a new motorcycle, my 3rd ninja, and yet again I can't remove the oil filter. I am thinking about taking it back and telling them that they tightened it, they need to loosen it. Either way I am going to call Kawasaki customer service and complain. And now it's Labor Day again and I don't get to ride my bike. I am starting to hate Kawasaki.
