5 ft/lbs seems about right to me. Originally Bultaco used awful star locking washers that I hate. Others may have different opinions. I use plane washers, 5 ft/lbs and screw lock. Never had a issue with coming apart in use.

 

I work on Diesel engine design for a day job and we calculate every joint to determine correct torque for application. (Part of design team on new Transit 2.0L engine "ECOBLUE"  just launched) Apart from the obvious joints like head bolts etc most joints use a lot lower torque than you would at first think or do by feel alone.

 

I have seen a lot of Bultaco cases with these threads stripped.Please not too tight.
