CB750K6 Cylinder Head Torque Settings
« on: November 30, 2016, 10:17:44 PM »
Going to fit the cylinder head tomorrow night and checked the manual - its an original KO genuine Honda manual - it specifies 13.7 -15.2 ft lbs for nuts but doesn't specify a value for torquing the 6mm bolts.
Are the recommended values for the K0 (from my manual) applicable to the K6 and what are the values for the bolts?
Also, would you torque the bolts after the main nuts?
The engine's been built with a cruzimage 836 kit including the head gasket.
I built my K2 engine with the same kit last year but forgot what torque settings I used! (its an age thing!)
Any help much appreciated
Thanks
Phil

16.63 on the head nuts and 8 on the 6mm  ;) But, I always do the head nuts at 17, once done leave overnight and then re torque.

Thanks Graham - should I torque bolts after doing nuts?
