LOL sorta what i said earlier.................CurtNow that everyone has told you the hardest ways to do it, here's the easy way.
Pull and lock the clutch lever on your bars. Pull the chain out.
To install the new chain, pull and lock the lever, feed the chain in from the top, while clicking the gear tooth by tooth with a screwdriver. If it doesn't come all the way out, bend a coathanger, grab the chain, and pull it out.
