The side stand mounting or pivot point is manufactured to a very loose tolerance which allows too much lateral play in the stand. The result is that the machine leans too far when placed on the stand and the bush in the pivot can kink and seize eventually wearing into the stand making it harder to extend or retract.
The symptom is the stand feels "sticky" when extending or retracting the stand. Adding to the slop, the pivot bolt is threaded under the pivot bush, accelerating wear of the pivot bolt.
The solution is simple.
Replace the bolt and make a brass shim.
The dimensions are 30mm OD, 10mm ID and 0.75mm thick.
Install the shim above or below the side stand pivot.
This removes the slop from the pivot.
The Kiwi solution by WPoll over at F650.com is to have a
new pivot bolt and bush made. Side Stand pivot pdf
Pivot Bush is 16mm OD, 10mm ID and 12mm thick.
The adjuster for positioning the side stand when retracted can bend and or work loose and fall off. When the side stand adjuster is missing or not adjusted correctly the side and centre stands interfere with each other.
It is worth checking from time to time to ensure it has not vibrated loose.
A replacement can be made from a 5 mm bolt, two nuts and a rubber foot about 20mm in diameter.
An enhancement to the stand to minimise the lean of the machine when on the side stand is to make a wider base for the stand about 15mm thick.
There are commercial products available but can also be easily made from some alloy and I hear hockey pucks work well. F650.us has a good write up on the hockey puck solution. See the link on the links page.
A word of caution though, with a plastic base the side stand can slip when parking on slopes, leaving the machine in gear is advisable.
The side stand can break off about 40 mm below the pivot. The reason is the pivot insert at the top of the stand does not extend far enough into the tubing and is not a tight fit, over time the metal fatigues and breaks.
The stand can be repaired by placing a piece of larger diameter tubing
over the top of the stand tube and then brazing or welding the larger
tube to the pivot and tubing.
You can see the tubing at the top of the stand in the pic.
The tube has been split along its length underneath and overlaps the
pivot and side stand tube so it can be brazed rather than welded.
The document below contains the information and pic's known
about the modifications.
