Drive chain
1. Drive chain tension check
NOTE:
Before checking and/or adjusting, rotate the rear wheel through several revolutions and check the tension several times to find the tightest point. Check and/or adjust chain tension with rear wheel in this "tight chain" position.
Inspect the drive chain with the center stand put up. Check the tension at the position shown in the illustration. The normal vertical deflection is approximately 35- 40 mm (1.4 ~ 1.6 in). If the deflection exceeds 35 ~ 40 mm (1.4~1.6 in) adjust the chain tension.
a. 35*^40 mm (1.4**-1.6 in
2. Drive chain tension adjustment
1. Loosen the rear brake adjuster.
2. Remove the cotter pin of the rear wheel axle nut with pliers.
3. Loosen the rear wheel axle nut.
4. Loosen the adjust bolt lock nuts on each side. To tighten the chain turn chain puller adjust bolts clockwise. To loosen the chain turn adjust bolts counterclockwise and push wheel forward. Turn each bolt exactly the same amount to maintain correct axle alignment (There are marks on each side of rear arm and on each chain puller; use them to check for proper alignment).

5. After adjusting, be sure to tighten the lock nuts and the rear wheel axle nut.
6. Insert the cotter pin into the rear wheel axle nut and bend the end of the cotter pin as shown in the illustration (if the nut notch and the cotter pin hole do not match tighten the nut slightly to match).
CAUTION:
Always use a new cotter pin on the rear axle nut.
NOTE:
Excessive chain tension will overload the engine and other vital parts; keep the tension within the specified limits.
7. In the final step, adjust the play in the brake pedal.
3. Drive chain lubrication The chain consists of many parts which work against each other. If the chain is not maintained properly, it will wear out rapidly. Without lubrication the chain could wear out within 500 km (300 mi), therefore, form the habit of periodically servicing the chain. This service is especially necessary when riding in dusty conditions.
1. Use YAMAHA CHAIN/CABLE LUBE or any of the many brands of spray type chain lubricant. First, remove dirt and mud from the chain with a brush or cloth and the spray the lubricant between both rows of side plates andon all center rollers. This should be performed every 500 km (300 mi).
2. To clean the entire chain, first remove the chain from the motorcycle, dip it in solvent and clean out as much dirt as possible. Then take the chain out of the solvent and dry it. After drying lubricate the chain to prevent the formation of rust.
Tubeless tires and aluminum wheels
This motorcycle is equipped with aluminum wheels designed to be compatible with either tube or tubeless tires. Tubeless tires are installed as standard equipment.
WARNING:
Do not attempt to use tubeless tires on a wheel designed for use only with tube-type tires. Tire failure and personal injury may results from sudden deflation.
Tube-type Wheel — Tube-type tires only
Tubeless-type Wheel — Tube-type or Tubeless tires When using tube-type tires, be sure to install the proper tube also.

To insure maximum performance, long service, and safe operation, note the following precautions:
1. Check tire pressure, before riding, adjust as necessary.
2. Before operation, always check the tire surfaces for wear and/or damage; look for cracks, glass, nails, metal fragments, stones, etc. Correct any such hazard before riding.
3. Always inspect the aluminum wheels before a ride. Place the motorcycle on the center stand and check for cracks, bends or warpage of the wheels. Do not attempt even small repairs to the wheel. If a wheel is deformed or cracked, it must be replaced.
4. Tires and wheels should be balanced whenever either one is changed or replaced. Failure to have a wheel assembly balanced can result in poor performance, adverse handling characteristics, and shortened tire life.
5. After installing a tire, ride conservatively to allow the tire to seat itself on the rim properly. Failure to allow proper seating may cause tire failure resulting in damage to the motorcycle and injury to the rider.
6. After repairing or replacing a tire, check to be sure the valve stem lock nut is securely fastened. If not, torque it as specified.
