OK heres how I got a rotor off yesterday
You see the 17mm socket on the bar?
I used that and a hammer to shock the 17mm headed bolt off the rotor.
I then used the 17mm socket and bar on the front of the crank with the
handle on the clutch casing to hold it still
and fitted an old oil fiter bolt on the rotor and got my stilsons on it
and screwed it in
It came off quite easily
If I'd had to get to the grunting,involuntary farting,
veins on my head standing out stage with the stilsons
it would have been wise to stop and use a solid bolt
(20x1.5mm pitch)
instead of the OF bolt
as there are limits to what abuse the OF bolt can take
AS soon as I felt the rotor free up I removed the OF bolt
and grabbed the toothed wheel and lifted it off with the starter gear in place
and put it straight in 2 plastic bags to stop the rotor magnets
picking up any metallic debris.
( you try cleaning up one of these when its picked up crap)
Note the needle roller assembly in the centre
this sometimes stays on the shaft, so I removed it and stowed it safe in the rotor as well
When I had the rotor in a cleaner area I gently pulled the toothed gear out
and examined the rollers and shaft
It all looked good and the shaft had no ridging that the 650s especially
are prone to, so I put it back together and stowed it safe
