OK guys when did you last give all the bolts a good going over?

I had the back wheel out and noticed a little verticle play in the rear swing arm. Close look shows the lower bush on the dog bone moving.
Closer look and the bolt looked loose, head not flush but threads protruding.

Take the load and "feel" bolt head ...out it comes!
Hexagon and shank no thread which was still in place.

By drilling into the vissible end and screwing a self tapper in .. slowly run it back out the way it goes in.

Mate had an F650 in the workshop for service and when we checked that the bolt was completly unscrewed and only in place due to the weight of the bike!

Take a moment to have a look at yours!

I think that this happens more often. I will check mine soon. I have heard about this problem before on here.

Lower rear pivot bolt

Thanks Ton.
Such a drastic failure I was sure its not a one off.
The wealth of experience out there is one hell of a resource.
As I am relatively new to the F its all a revalation!

Now on the regular check list hoho.

Bolt location

The bolt is the one that goes through the lower part of the suspension unit and anchors it to the "dog bone".

Put the bike on the main stand.
On the near side right under the suspension unit.
There are a couple of other plates that create the leverage and geometry that pass close the head making it a bit tricky to get a socket on.
If you want real good access whip the wheel out.
Remove the rearmost cross bolt and access is easy to the ofending bolt.
