Torque cyclinder head at 600 mi. service ?
I'm about to do the 600 mi. service on my 2005 ZX-10R. Looking at the service manual under "Bolt and Nut Tightening" it says to torque the "Cylinder Head Bolts". This is a fairly big job because it requires removal of a lot of parts to get to these bolts (upper fairing, fuel tank, air cleaner housing, throttle body assembly, and then cylinder head cover)
Although I'm planning to do the work myself, I called the dealer where I bought the bike to get advice on the cylinder head bolts. He seemed to be surprised and said "we don't normally do that but if it's called for we'll do it." Didn't seem to know how much it would cost.
Question: Is tighening the cylinder head bolts really necessary at the 600 mi. service ?
