Well that was the correct part #.  It is used on EVERY new bike from the 696 to the 1198.  Unreal that the dealer's parts catalog doesn't list it for my bike.  Oh well, problem solved.

So any advice on fitting the new seals?  Quite difficult with the arms still in.

Best to remove both rocker arms.

Getting the closer rocker back in with the spring is no picnic.

When I did this with Rule62 we did the following:

Remove spark plugs.  Turn engine over 'til piston is at top dead center (on the valve you are working on of course). 
Feed in a little string or rope into the spark plug hole to cushion the valve (might need to drop the piston a little to do this)
Hold halve with forcepts.
Remove clip next to opening rocker, slide it out of the way and remove opening shim.
Depress closing rocker and remove half rings & closing shim.
You will have to rotate the motor to turn the cam into the correct postions to do the above.   
With piston at TDC you can remove forcepts.  You can now control the height of the valve by turning the motor, it will simply rest on the piston.  Don't drop the valve into the cylinder.
Drop valve far enough to remove old seal and install new seal. 
Put everything back together.

Yeah... that rope in the cylinder trick worked like a champ!  No way the valve wa gonna fall in the cylinder like that.
