  • Header bolts torque spec's

    Does anyone know the torque spec's for the header bolts?

    I checked the service manual and I don't see it listed.

    Hmmm... The only things I see are the generic spec by bolt diameter and the callout for "Cylinder Head Bolts"... I don't see any specific numbers for the headers, but I'd be inclined to use the head bolt torque specs for the headers. Since you're tightening into the same part (top end), it makes sense (to me) that the torque would be the same.

      Only thing I found is in the service manual 2-7, general torque settings, thread diameter 8mm = 10 - 13.5 ft. lbs.

      I also saw another thread on a Z1000, says his owners manual says 12 ft. lbs. on header bolts which jives with the above.
