I just installed 14T sprocket on my S2R1000 and now the chain is sliding on the top chain slider. Is this normal? Since the diameter of the sprocket is now smaller I don’t know if there is anything that could be done…right? (accept changing the rear sprocket which I don’t want to do now). Also according to manual the chain tension should be between 22-27mm of play (top of chain to swing arm). when I sit on the bike it seems little tight. Is this me? Thanks!
