Hey all, I'm working on a friends 95 vmax 800. Can anyone tell me the head torque pattern and specs. also cylinder nut torque?
Thanks in advance..........
 

base bolts are 20 ft-lb. the head bolts 16 ft-lb. each set of two heads has sequence. go side to side when torqueing. #1 bolt will be first bolt in middle of head, #2 will be on other head at front. and so on. there are 10 nuts total per head set. 3:16 (yammie tony)

This is straight from the Yamaha service manual. Happened to have it out as I'm reassembling my 800.
