I do not know if this is the right thing to do, but I was finding it hard to judge if my Genesis was shifting at all, so I picked it up and accelerated so that I could hear the shifts easier. I found this far easier than listening while the thing was traveling at a great rate of knots.
I had it shifting really nice, but the snapped the crank, (Not shift related, (I hope)).[

New crank is in now, so I'll have to complete its tuning now.
