Re: rear suspension
I meant slack due to suspension movement, not jus general slack. yours at full unloading it will be wherever and however you regularly set it, but then when you sit on the bike and hit a bump the chain will start seeing major slack. I'm not talking about one half link here or there. I mean like, 3 or 4 or 5 links. Or more.
Here is how I set my tension. My jackshaft plates have slots for the bearing mounts. I set the tension in the middle chains then use engine position and wheel position to set the outside two. But I don't have geometry changing suspension to worry about.
I don't always listen to Alice in Chains..... but when I do, SO DO THE NEIGHBORS
