New to me '03 SW

Greetings. I just purchased an '03 with 2500 (two thousand five hundred) miles on it. It is in really nice shape. I plan on going through and changing the oil, final drive oil and coolant before putting it away for the winter. Minnesota resident. I am on the fence about doing the brake fluid, still looks nice and clear through the reservoir windows.   I've put a few hundred miles on it since picking it up and it is a blast to drive. Coming from 750cc sport bikes, as I have aged (50ish) to this has not been a disappointment. Wished I would have done it sooner.
There is a ton of good information on this forum that has provided me a lot of insights to SW ownership.
Had an interesting time at the local Honda dealership trying to purchase the final drive drain and fill seal washers and coolant drain seal washer. The service manual calls for replacement of these when re-installing. Anyone else had issues locating these? Not sure if they got the right parts for me, will see when I get the old ones out.

Welcome . I didn't have to change my washers cause they can be reused after a little degrooving using a strip of emery cloth.
