Ever since I got the Ryker, there to seemed to be a little up and down play on the end of the handle bar. The locking mechanism was binding a little whenever you unlocked it and locked it. I took some liquid graphite, and sprayed it underneath it and worked it back and forth, that made a world of difference as far as binding up goes. There’s a flat head screw that I figured might tighten the locking lever up a little, and take out the play. I found out that it’s ass backwards, you loosen it, and it tightens up the locking lever. All you need to do is turn it just a little, half a turn or full turn, makes a big difference. Play is gone now.
