i'm putting a new 48 tooth sprocket on my bike to replace the 42 tooth that i bought it with. old chain is, well, old, and too short to boot so i bought a new RK o ring chain. got the old 111 link chain off easy enough and it's time to put the new chain on. the new chain is 114 links and it looks like i'll be removing 1 or two links. so, i'm thinking i'll set the axle just past center toward the front, press on the master link, rivet, adjust, ride then adjust again. how much stretch can i expect initially?
