Quick and easy chain replacement
Here's a quick easy way to change your rear drive chain. First loosen the axle nut, brake stay, and both chain adjusters, then slide the whole rear wheel assembly as far forward as possible. Next turn the wheel until the master link is located at about 3:00 o clock (9:00 o'clock on Sportsters) remove the master link and let the bottom side of the chain drop, put the master link back into the top half of the old chain that is still draped over the top of the sprocket, hook the new chain onto the other side of the master link, put the bike in neutral, then using the bottom part of the old chain, simply pull the new chain through. Replace the master link. Remember, the open end of the clip goes away from the direction of travel. Re-adjust the chain tension and your set to go. Don't forget to re-tighten the axle nut and brake stay.
