After searching this site for as much info as possible, I finally dove in. My bike had 19/40 sprockets and that is what I stayed with. I turn 4000 rpm at 80mph.
The changing of the rear sprocket was straight forward. The front was a little more challenging. removing the cover was straight forward. The nut that holds it on is 1-7/16" or whatever the metric equivalent is. I do not typically have sockets this size, so I borrowed one from work.
The old chain had a master link that was the clip type. The new one was a rivet type that the side plate is pressed on. Of course I did not have the special tool to install it. I looked at the closest bike shop and they would have to order it. I ended up using a C clamp and a spacer to press it together and flared the head with a punch and bmf hammer. I aligned the master link with the tire and placed a piece of metal stock between the two for a brace to hammer on.
The task is not tricky, if you have the right tools to begin with. It should of taken 2-3 hours to complete.
I noticed on my test ride that the bike has less vibration now. I purchased the parts at my dealership for $225. I could not find a vendor on the internet that had the same sprockets. Several were close (AFAM), but not exact. Everyone sells chains.
