For the sake of science (And because I couldn't find it anywhere on the internet) I counted the required revolutions of the crank between true complete 100% Timing Chain Alignment Check at TDC as per the diagram in the FSM.
1. Every 22 revolutions of the crank, the double orange links on the secondary timing chains line up with the proper dimples on the outer cams at TDC.
2. Every 1100 revolutions of the crank, the yellow links on the primary timing chain line up with the proper dimples on the inner cams at TDC and the double orange links on the secondary timing chains line up with the proper dimples on the outer cams.
That's once every 50th time condition 1 happens, condition 2 will happen!!
So if you're checking your timing, you may have to rotate the crank anywhere up to 1099 revolutions to check it.
Helpful Hint:
Remove the sparks plugs before starting. It makes it a hell of a lot easier. Doh!
