CB400/4 ENGINE STRIP, ASSESSMENT AND REBUILD BY JULIE - NOW COMPLETE

Moorey:
Did you have to gap the piston rings at all.

mike the bike:
As Nigel said;  the camshaft position is unimportant.  This is because of the 2:1 ratio, the camshaft rotates half the speed of the crankshaft.   Think of the sizes of the sprockets - the camshaft one is bigger.
Enjoying your thread,  I like the way you're checking and refurbing everything including the points wiring.

No gaping needed. Bored out to .50, fitted .50 rings to .50 pistons so everything fitted perfectly.

JamesH:

paul G:
