Improvement day.
Winter is just about here, so I went out for a short ride to warm things up prior to prepping for winter storage.
Too cold to ride? Nah. Just a tad below freezing.
Back home and ready to change oil. The new adapter is to the left of the filter
Installing the adapter. At about this point is where I'd expect the 'torque enhancer' to fall into the drain pan.
Done.
The oil capacity is increased by about a liter or so. Should run a little cooler in stop and go traffic now.
