Unusual noises may indicate mechanical issues such as loose components, worn bearings, or engine problems. Inspect the ATV for any loose or damaged parts, and check the condition of the drive chain and suspension. If unsure, seek professional assistance.
If the brakes are not performing well, check the brake pads for wear, inspect the brake fluid levels, and ensure there is no air in the brake lines. Also, inspect for any leaks in the system and replace parts as necessary.
