torque specs

[Dannys400ex]

can someone tell me the proper torque specs when putting the motor back together?im getting ready to put the 440 in and dont know the specs for all the bolts, or the proper break in.


thanks

cylinder mounting bolts-33ft. lbs
cylinder studs- 15 (the studs that go in the cylinder that the head nuts bolt to)
head nuts-33
head cover-17
cam sproket bolts-15
these are all in foot pounds.

also on the break in, dont ride it too easy like most people do, ride it kinda hard but dont just beat the hell out of it for the first few hours, riding it kina hard for the first few hours will make your rings seat better than going real easy on it. also mix your throttle and rpm ranges up as much as possible for these first few hours, dont just ride for long periods at the same rpm. and dont use any synthetic oil until after it is broken in.

no, its 15 on the studs, i guess because they tighten up a little more when you torque the head nuts down on them.
