Right, managed to drill the snapped bolt out of the head finally Ordered the bolts (as I lost one other one too...) so should be here tommorrow.
So to make sure I dont do it again, does any one have the torque settings for the camshaft caps/covers?
Also for the cam top cover bolts as thats got to go back on afterwards.
Found the readings for the head bolts already:
Initial torque setting is 10N-m/7 lb-ft, final torq is 27N-m/20 lb max of 29N-m/21 lb-ft.
So just the covers and cam head top cover needed if anyone has them? Cant find it in the gk73 manual (figured it would be the same as the for my gk76).
Cheers,

ok parts a through f (camshaft caps) 8-12nM
head cover initial torque is 6 nM
head cover final torque is 8-12nM

Thanks, but I no longer trust my torque wrench as it just stripped two bolt heads....farking bike.
