The tentioner pulley must be tight, before you pull the pin on your tentioner. The two pin holes on the outside of the pulley, should be at 11 and 1 oclock, To at least get it good and tight. If, your balance shafts are out you dont have to line that up at all. Idk /ubbthreads/images/graemlins/dunno.gif Make sure both cams can even line up, you might have to turn just one cam before you put it at tdc.
