How do you tighten a chain on a raptor 250?

To tighten the chain on a Raptor 250, first, place the ATV on a level surface and ensure it's in neutral. Locate the rear axle adjusters on both sides of the swingarm, then use a wrench to turn the adjuster bolts evenly to tighten the chain. Check the chain tension by measuring the slack; it should have about 1 to 1.5 inches of play. Once adjusted, tighten the axle nut and recheck the tension for accuracy.
