It finally got warm enough for me to start hauling all the crap out of the back of this thing (bicycles, inverters, battery chargers, computer cases, shelves) so I could have enough room to throw in the junkyard seat that I bought at the start of winter. Fits great, matches the others! The armrest on the new seat is a bit lazy, but that's life.
Next up is the air filter, which is somewhat annoying to get at because of the oversized battery the previous owner chucked into it.
