The owner requested inspection, oil-cooled maintenance, sel point maintenance 20, and Newtech oil change.

First, we’ll replace the generator damper. Even before replacement, it was relatively soft with no play.

There’s a rubber cover on the wiring, but we’ll remove it.

Running the side stand switch wiring through here keeps things simple.

Thread it through the inside of the bracket.

The engine damper was nicely loose.

Let’s clean the case side before reassembling.
