Twin Cylinder Head Tightening (2)

John Jordan from Roadholder

Another recommended order for tightening down Norton twin cylinder head bolts

This revised sequence starts at the centre and works outwards.

N.O.C. experts have advised that this method should be used on all Dominator Twins. However, one owner who tried this and had oil leaks then reverted to the original and achieved better results.

The moral seems to be that if your cylinder head leaks after doing it the first way, then try the other.
