When you replace. "To stagger or not to stagger ...that is the question"

I chose to stagger mine.

George, that only works on Hyvo primaries, like the 400/500/550's. 750 chains are different, they are not Hyvo, they are a lot thinner and there are 2 of them, side by side.
Ding dong....getting ahead of myself Julie!

Nurse Julie, how are you doing. You did the camshaft on this engine a few years back.

Seemingly new chains have a measurement of 65mm, at 70mm they are done.

Wear limit spec is 70mm. Does anyone know what this measurement is with a brand new chain?

If you place a primary chain upright and the top row sags to contact with the bottom row the chain is finished. As to how close you'll let it come to that I guess is up to you.
