I've been reading the rephase posts and OK, I understand why it works and how the 13 spline center pin locks an XS650 rephase into 277º as the closest you'll get to the 270º optimum unless you pay a fortune for a custom made stagger-splined pin.
BUT
Which piston goes first? Does the left lead the right or the right lead the left, is there a consensus?
