EXHAUST HEAD BOLT TORQUE SETTINGS??
 
I have just bought a new stainless Predator full system for my 2002 4PT
anybody know the correct Torque setting for cylinder head bolts? also
anybody any thoughts on re-jetting etc.. manufacturers say none needed (I
have got a system from the same manufacturer on my ZZR600E and they said
that needed no re-jetting and it was fine). Any thoughts would be
appreciated!

Exhaust pipe-to-cylinder head nut? The Clymer for 83-89 models quotes 10 Nm (7.2 ft-lb), if this helps? I cannot think the later models would be much different.

Funny, I have never thought to look before and just done it by feel. I was (pleasantly) surprised to see this torque setting quoted.

Ciao, Geoff
