Re: Torque spec's in reply to indy bob, 12-07-2017 10:38:48
The first thing to do is check the valve recession. None were in spec when they were new. You want 0 to 0.015 recession on the intake valves and then set the stem height of the exhaust valves to match. I don't know how old your 550 is but some had intake seat when new. None had exhaust seats. Questions?
