Firstly.
Calm yourself, you are VERY unlikely to need to take anything apart.
Below I set out my method for unsticking BMW clutches, trust me I have been doing this for 37 years (commencing 1978 when I caught a R100RS sized dose of incurable Airhead disease).
All Airhead clutches are apt to get a bit stuck if the machine has not been ridden for a while, especially if the weather was wet when the machine was last ridden.
My (soon to be patented) method is:-
Put bike in neutral and start engine, warm up until engine at normal operating temperature.
Wheel bike to top of a small slope (the driveway up our gutter is about 5 inches fall in 10 inches distance and is more than sufficient for this) alternatively have an assistant stand behind the bike, ready to push.
Paddle foot the bike to the top of the slope with the engine running and as soon as it starts down the slope, bang it into first gear and ride off with the clutch leaver pulled in, change gears gently remembering that there is no disengagement and, if possible, give it a bit of welly. I have never had a clutch take more than a few hundred metres to come free.
Alternatively, have companion push you down the street with the engine running, as soon as walking pace is achieved, select 1st gear and accelerate away - proceed as in example above until clutch frees itself.
