PERIODIC MAINTENANCE AND MINOR REPAIR G Use only the recommended quality brake fluid, otherwise the rubber seals may deteriorate, causing leakage and poor braking performance. EAU22720 EAU22760 Changing the brake fluid Have a Yamaha dealer change the brake fluid at the intervals specified in the NOTE after the periodic maintenance and lubrication chart. In addition, have the oil seals of the brake master cylinder and caliper as well as the brake hose replaced at the intervals listed below or whenever they are damaged or leaking. G Oil seals: Replace every two years. G Brake hose: Replace every four years. Drive chain slack The drive chain slack should be checked before each ride and adjusted if necessary. EAU22770 Recommended brake fluid: DOT 4 G G G G Refill with the same type of brake fluid. Mixing fluids may result in a harmful chemical reaction and lead to poor braking performance. Be careful that water does not enter the brake fluid reservoir when refilling. Water will significantly lower the boiling point of the fluid and may result in vapor lock. Brake fluid may deteriorate painted surfaces or plastic parts. Always clean up spilled fluid immediately. As the brake pads wear, it is normal for the brake fluid level to gradually go down. However, if the brake fluid level goes down suddenly, have a Yamaha dealer check the cause. To check the drive chain slack 1. Place the motorcycle on a level surface and hold it in an upright position. NOTE: When checking and adjusting the drive chain slack, the motorcycle should be positioned straight up and there should be no weight on it. 2. Shift the transmission into the neutral position. 3. Move the rear wheel by pushing the motorcycle to locate the tightest portion of the drive chain, and then measure the drive chain slack as shown. Drive chain slack: 30.0-40.0 mm (1.18-1.57 in) 6 6-22
