Hi All

Reassembling 500 Bullet classic engine and cylinder head I noticed that 4 of the Rocker mounting bolts are black and 4 are bright finished... Is this for ant particular reason and do they need to go anywhere in particular or does it not matter?

There is no reference in the Wshop manual for the orientation of the rocker studs...


The Black 'ground' studs are fitted diametrically opposite the pushrod - valve


eg: on the exhaust they are fitted left-rear & right-front


Inlet rocker block left-front & right-rear.

Thanks Tim.
