I observed the wheels hadn't been balanced. Surprised Yam doesn't do this from the factory. I thought someone said there was the 19mm removal tool in the tool kit so I went on a hunt for that. Not under the seat, check youtube. Under the side valance, surprise, and even better quarter turn fasteners. Found the battery also, surprised there again, the terminals were not tight, maybe the cause of the sleepy start ups. Another surprise, there is the dongle for the battery charger. Yam does a pretty good job of thinking of some things. So on to the tire balance, starting on the rear, the cush drive came apart and there was a little tug of war to get all that figured out. The rear wheel was out 1/4 oz. so I was thinking this is gonna be a waste of time. The front was easier to remove. And it was out a full ounce. I think and hopefully found the buzz in the handlebars. Around town at lower rpm it is pretty smooth, the buzz was noticed on the highway, so hoping that is fixed.
See you next time.
