I had somehow lost track of when I last changed the oil on the Toaster. It was certainly not needed for mileage, but it was due for the once per year change. There was a filter kit, including gasket, and crush washer in the parts stash, so after a ride to warm up the oil, it got drained. It was fairly clean, and the filter was free of any debris. I usually save this for the end of the season, and put the bike away with fresh oil, but in this case, it has more riding to do so an early change made sense.
