It should take up the slack soon. My gen4 took abit of time to click to the next notch during/after the break I period.Just got back in from a nice morning ride one mine. It's so damn hot here in SE Louisiana, have to ride early or die from heat exhaustion. Just broke 1950 miles on her, she's running great except for the useless cam chain tensioner. Think I'm going to try adjusting it out a notch this weekend.
