[QUOTE="dirtrider998, post: 231590, member: 5763"] just assembled a mega moto 212 tillitson from GPS. I tightened the 2 U-clamps that squeeze the handle bar really well using an allen key and tapping it with a hammer instead of twisting with the hand, seems I got them as tight as possible but the handlebars slips a little forward/back, like when I pick the front end up to turn the bike around the handlebars pivot forward.
