I own a yamaha 2000 xl limited 1200cc. Im in the middle of doing a top end rebuid and starting to put eveything back together. One of the problems I have is not knowing the specs of Nm torque each bold needs to be tightend on the Heads,exhaust,maifold etc. Is there anyone who can help me on this issue? or give me a link to where it show technical specs of rebuiding a yamaha.
