Valve clearance problems

(1/1)

tosh:
Hi all,  I finally decided to sort the oil seep from the inspection covers on the 79 CB650z due to the PO having stripped the threads. So 2nd hand cyl head cover bought c/w tappets in place. After tarting it up and fitting it I go to set the clearance. Now I can set cyl 1 ,3 + 4 fine but cyl 2 I just can’t get any movement on either tappet at the respective 1.4 T mark even with the adjuster backed right off. I’m at a bit of a loss as to what’s wrong so any suggestions greatfully received  ???

hairygit:
Turn the engine a full 360 degrees clockwise (views from the timing side) and the tappets should be free.

As Hairy said; Turn til T 1.4 set the 4 tappets and then 360 degrees til T 1.4 again to set the other 4. Forget about the T 2.3  ;)
