[QUOTE="ossagp, post: 211823, member: 1650"] I think having it lined up is more important than having it too loose. one of Joe Lowry's friends showed me that on a crusher about 50 years ago. (Jack James was his name.) He spent a long time getting things shimmed and in place, but told me that all it would need as long as alignment was kept was for it to be lubricated. That thing ran forever. I was surprised at how easily a chain would fly off when we started building long travel back ends, if it was the slightest bit out of alignment. It seemed no amount of tensioners etc would keep them on if you didn't have it centered. once centered, maicos and cz's (yes ossas too) with about 4 inches between the swingarm pivot and the sprocket would stay in place, loose enough not to bind, if the chain was set in the center and your pivot bearings were good.
