1. Park the ATV on a level surface and turn off the engine.
2. Locate the front chain adjuster, which is located on the left side of the ATV, near the front sprocket.
3. Loosen the lock nut on the front chain adjuster with a wrench.
4. Turn the adjuster bolt clockwise to tighten the chain, or counterclockwise to loosen the chain.
5. Check the chain tension by pulling it up and down at the midpoint between the front and rear sprockets. The chain should have about 1/2 inch of play.
6. Retighten the lock nut on the front chain adjuster.
7. Start the ATV and test the chain adjustment by riding it around for a few minutes. If the chain is too tight, it will make a grinding noise. If the chain is too loose, it will skip teeth on the sprockets.
