recently bled my clutch which involves removing the radiator. When I was putting it back togeather, the lower radiator sleve didn't seem right the way they had it so I flipped it since that make more sense.
looking over the diagram today I noticed the diagram shows it how I have it now except now the washer(23) goes under the bolt which is how it came, then through the sleve and bushing.
This diagram is for a 2020. It makes me wonder if the washer is supposed to be on the inside like the diagram shows and the assembly line worker has it under the bolt itstead. I'm glad I flipped the sleve like it shows in the diagram now.
here is a picture of how it originally was on my bike and how it should go in the diagram. Just something to look for if you do the job.
