[. . . ] Sensor N2 Sensor R fig-1 If length is below 30mm, it must be replaced. Smear with loctite 5699 and screw with torque 25 kgf-cm in assembly. SERVICE LIMITS: 30 mm TORQUE: 25 kgf-cm Sensor N1 Sensor F Shift Motor Shift Spring and Gear Remove mission side cover and other parts. Measure open width of shift spring as fig-2. Shift Spring fig-2 If open width greater than 5mm, it must be replaced. SERVICE LIMITS: 5 mm Shift Gear 27 Shift Motor Check shift motor whether it's action is normal as follow data: Disassembly mission side cover, parts of shift mechanism and mission cover. Get seal and bearing after disassembly shift motor of mission cover. Replace it if necessary. Brush Seal Bearing 7. 4 AUTOMATIC CONTINUOUS VARIABLE TRANSMISSION This transmission is the combination of automatic centrifugal clutch and V-belt continuous variable transmission, which can change the transmission ratio automatically. When engine speed increase, the drive pulley will be push to belt by the centrifugal force from six rollers. Then the pitch circle of belt in drive pulley will be larger. The belt at driven pulley is forced to move to the center of shaft, then the radius of pitch circle is decreased. The transmission ratio is therefore altered by the alteration of pitch circle's radius. (In the drawing, "H" means high speed, "L" means low speed) 7. 5 CONTINUOUS VARIABLE TRANSMISSION V-Belt Made of rubber fiber, resistant to head, pressure and abrasion. The inner side of the Belt is toothed. Drive Pulley Due to the increasing engine speed, the rollers push the movable drive face by centrifugal force. Then the belt is pressed and enlarges its turning radius. The aluminum fan is installed on the exterior of fixed drive face. It can reduce the belt temperature. 28 Driven Pulley Because the revolving radius of V-Belt at the Drive End is enlarged, the Face Comp Movable Drive is squeezed out by the V-Belt at the Driven End to shorten the revolving radius. There is a Torque Cam on the Movable Drive Face. When the outside load is higher than the engine's output, the pulley of fixed shaft and belt slip to make the Movable Drive Face move along the inner side of Cam and compensate to increase to high torque (toward to low speed) and make the engine maintain smooth running with original revolution. 7. 6 GEAR BOX (For RXL 90R) Reverse Shaft Comp Sensor Drive Shaft Comp Drum Gear Shift Fork Fork Shaft Counter Shaft Comp Remove mission side cover, parts of shift mechanism and mission cover. Inspect gears for wear, scoring, chipping or break. The gear ratio of front gear composition is about 47 31 × 15 11 49 49 31 × × 15 16 11 The gear ratio of reverse gear composition is about 7. 7 ELECTRIC SELF-STARTER MECHANISM Starter Motor is installed on the upper side of engine. The starter motor can act only when the left hand brake is applied. 29 ELECTRIC SELF-STARTER MECHANISM KICK STARTER 7. 8 KICK STARTER This kick-starter arm is on the left side of engine. [. . . ] Contact with skin or eyes may cause severe burns. Wear protective clothing and a face shield. If swallowed drink large quantities of water or milk and call a physician. 56 12. 4 BATTERY INSPECTION Battery is under the seat, you can see this battery from the left side. Measure the battery voltage using a voltmeter. VOLTAGE: Fully charged: 13. 1 V Undercharged: Below 12. 0 V BATTERY REMOVAL Remove the battery holder bolt nuts. [. . . ]
