Cylinder head flange bolt torque ? 78 cb550k
« on: June 05, 2021, 06:41:00 AM »
What do you guys torque the 2 flange bolts (#13&14) to? The manual says to torque the 12 8mm nuts 14.46-16.63 ft-lbs, but that seems like alot for those 2 flange bolts.  Thanks

tighten them like any 6mm bolt, meaning gently by hand is sufficient.
the general torque value for 6mm specified in the manual applies, but be careful as even that can strip the threads in the alu.

That is what I am woried about at that torque value.  Just trying to get an idea on how much torque is sufficient to prevent leaks.
