Just did the swing arm service and I highly recommend it to anyone who hasn't done theirs yet. I got great piece of mind and understanding after taking it all apart, checking, cleaning and re-lubing etc. Also, it's a great excuse to go through the rearsets and do the splines. It was all so perfect and clean I didn't want to take it out.
While I was at it, I changed out the rear shock with a Hagon, and yea the ride, control and feel are awesome but I ran into a problem with the lower shock bolt.
Here it is. If the new shock you buy has lower mounting tabs that are thicker than the stock ones and they don't supply you with a new special bolt, when you tighten it, the two tabs will squeeze together and contact the link at an angle. 99% right is wrong.
I had to take a stainless washer and shave it down to make an additional spacer for the bolt. When tightened down, you should be able to just about get a fingernail between the bolt and the shock tab. The top bolt doesn't have this problem. It's got a long spacer. The bottom bolt spacer is part of the bolt, called a bushed bolt. When you tighten the bolt, you're stacking the bolt head, spacer and sleeve against the nut side. The bolt head side is just for support and guidance.
I don't know how it is for Penske or Öhlins shocks when it comes to the thickness of the tabs or what they supply but you may have to take some measures to make things right.
The quality of the Hagon seems fine. I couldn't see the thousand for a racing shock, and it's able to be rebuilt like the others. Hope this helps. I guess just make sure the lower bolt shoulder is off the tab after tightening.
here's a shot of the new shock. The lower mount is aluminum. Thicker than the stock stamped mount.
