The head cover bolts are 7ft-lbs and you'll have a singl smaller on eup front near the exhaust that will be 4 or 5 ft-lbs.
The BIG head bolts the bolt the head down to the cylinder are 17 ft-lbs.
Be sure to use an in-lb torque wrench on the head cover bolts. fl-lb torque wrenches aren't that accurate that low.
7 ft-lbs = 84 in-lbs
5 ft-lbs = 60 in-lbs
4 ft-lbs = 48 in-lbs
Dont go to tight on the head cover bolts. The heads will twist right off. Great quads, crappy bolts.. lol.
