My dirtbike's chain was loose when i was riding, so it came off, i put it back on, >>>>>>>> PLEASE READ ADDITIONAL INFORMATION FOR THE REST.
SOO after i put it back on, then i tightened it as much as i could because the bolts to tighten the chain were on backwards b/c the guys did it wrong when they fixed my inner tube on my back tire, so we tightened it as m,uch as we could backwards, on both sides, and i rode again in 1st gear then i got to second i think.., then it popped ouit of place and i heard my bike go rearrrrrrrrrrrrrrr
!!!! as the chain fell out of place so i cut it off. NOW it was all rapped around my sprocket and stuck on a screw on the side of the tire, so long story short, We got the chain offby cutting the masterlink then putting it back together and putting it back on the bike, THENN i could not change the gear's, THE BIKE WAS OFF THE WHOLE TIME I WAS TAKING THE CHAIN MASTERLINK OFF AND ON THEN PUTTING IT BACK ON AND ALL THIS, THIS BIKE IS OFF, the sprocket wont move AT ALL, with or without the clutch, nothing is working, PLEASE HELP!!!
