I don't know Ben, but if you trust him, you trust him. I'm just saying close enough is not, right/correct. Moving the chain is my suggestion, because I always set the chain correctly or you have to adjust everything, with the notion timing is off a tooth. I'm about to check torque on my head studs, so the mechanical timing
Should be the same as when I set it, I can also look at the cas and my marks to make sure it where I set it, think of it as a blueprint.
