this has been discussed before. like I said before, I come from the smiling chain is a happy chain school that ferret briefly mentioned. but it took no time at all for me to discover that doesn't work for the CB. under the least heavy acceleration my chain skipped teeth. I've never had that happen before. there is something different about this chain / sprocket set up. so I simply tightened it until it stopped skipping teeth under acceleration. how far a chain flexes when you pull on it depends on how hard you pull on it. it is why Harley has a tool that controls the amount of tension used to push / pull the belt on a Harley to measure slack. the other consideration is suspension travel. if the tautness of your chain interferes with suspension travel, you will have problems. one poster mentioned breaking the countershaft... I find that hard to believe, would think the chain would snap first. I've seen several chains snap. anyway, that's my .o2 worth.
