I love your videos professor. You are like the Dave Ramsey of motorcycle maintenance. As a new owner of a '20 K1600 GA, will be reviewing all your vids. Thanks!!
So far I've only had to check the valve lash with no adjustment. If I have to do an adjustment I'll do my best to record it. The final drive up to this point has only been a drain and refill.
My LT has some stupid design aspects, but I have never seen anything as stupid as that drain plug up inside the sump. That is even dumber than my LT having a spin-on filter that is inside the sump. At least the filter can fall off and get lost in the sump.
