I have 2012 848 corse,had 600 mile service done recently,dont think shop adjusted chain,according to repair manual chain should have about 30 mm of slack but it also says chain should touch lower chain guide but if this is true how do you know how much slack is actually in the chain if its hitting the guide.....

Adjusting the chain tension
Put the bike in gear
Move the motorcycle slowly until you find the point at which the upper section of the chain is most taut.
Place the motorcycle on its sidestand.
Push the chain upwards with a finger in correspondence with the centre of the swingarm.
The lower length of the chain should deflect by approximately 33 to 35 mm.

Also, when you sit on the bike there is less slack in the chain than when there is no weight.

So if it is hitting when you check it, it will not when you are riding.

You never want the chain to be too tight.
That can damage the seals and bearings in the transmission.
