when i replace them i chase the threads with a cleaning tap then blow out the holes clear. i used a bit of blue Loctite reinstalling. just seat them but if you need a torque spec its 12-15 ft lbs. its set by thread pitch and material etc. (typically)


this one will stay stock (the 71) but its just dismal the factory setting pre 73. the current replacement is a 159-p4 jet tube, but these require a,hex jet vs round. as an fyi. however, what im going to do is retrofit a set of vm34s i have for the black 72. endless... lol.
