Remove your exhausts.
Remove the cable end plate - remembering the nut is left hand thread (goes the 'wrong' way to undo).
Remove the mounting bracket.
Put the washer and nut back on the shaft, then lever the shaft out of the barrel - I use the prongs of a claw hammer, but others are more subtle!
The circlip you might be able to see doesn't hold the shaft in, it just secures the rubber bung.
You may have to pull bloody hard if the valves are badly coked up, but don't worry, there's nothing but crud holding them in. That'll teach you to clean them more often!
When the shaft is out, the two part valves should be removed through the exhaust port.
I clean them with a Scotchbrite nylon scrubby pad and the odd squirt of WD40.
Let us know how it goes...
