Tried different mechanic/dealer type place than usual as they gave me a good price for chain/sprocket replacement.

Arrived a bit early but they got straight to work, and all sorted pretty quick. All good so far.

Got on bike to leave, into 1st, clutch out, nothing. Tried second. Same. Messed about looking like a numpty, still not going anywhere. Called mechanic out, and off comes sprocket cover, mutters about just took off clutch arm, didn't adjust it. Pulls off clutch arm, other mechnics gather, confer, they get it together again, check bike goes into gear now, so all is well again.

Or so I thought. Onto motorway, open up at 5,000rpm to move into traffic, bike revs, no acceleration. Avoid lorry. **** self. Clutch now slipping. Stop at next junction, adjust at lever but can't solve. Back to mechanics again, and they take apart again, and now appears to be sorted.

Before I condemn them as eejits and never darken their door again, is this something that could happen by chance and we were all just victims of a bit of bad luck and something dropping out of adjustment accidentally, or does this seem like cowboy slapdash work?
