MAINTENANCE FUEL HOSE Remove the seat (page 2-4). Check the fuel hose for deterioration, damage or leakage. Replace the fuel hose if necessary. THROTTLE OPERATION Check for any deterioration or damage to the throttle cable. Check the throttle lever for smooth operation.
Page 54 MAINTENANCE CARBURETOR CHOKE This model’s choke system uses a fuel enriching circuit controlled by a starting enrichment (SE) valve. The SE valve opens the enriching circuit via a cable when the choke knob on the handlebar is pulled up. Check for smooth choke knob operation and lubricate the choke if required.

Page 59: Engine Oil Change & Filter
MAINTENANCE OIL CHANGE Pour the engine oil after replacing the oil filter (See below). Change the oil with the engine warm to assure complete and rapid draining. Start the engine and let it idle for a few minutes. Stop the engine and remove the oil filler cap. Remove the drain bolt and drain the engine oil.
Page 60: Engine Idle Speed
MAINTENANCE ENGINE IDLE SPEED Inspect and adjust the idle speed after all other engine maintenance items have been performed and are within specifications. The engine must be warm for accurate adjustment. Ten minutes of stop-and-go riding is sufficient. Warm up the engine, shift the transmission into neutral and place the vehicle on a level surface.
Page 61 MAINTENANCE OIL CHANGE Place the vehicle on a level surface. Remove the oil filler cap and drain bolt to drain the oil. When the oil is completely drained, install the drain bolt with a new sealing washer. TORQUE: 12 N·m (1.2 kgf·m , 9 lbf·ft) Fill the final gear case with the recommended oil (page 3-12).

Page 365 TECHNICAL FEATURES A.P. SURETRAC TORQUE BIASING FRONT DIFFERENTIAL CONSTRUCTION In this mechanism, torque is transmitted through the differential using a cam and follower principle. The differential is groove-fitted in the differential case (which receives torque from a ring gear) so that the cam followers can move to the left and right.
Page 366 TECHNICAL FEATURES CONVENTIONAL TYPE Torque transmission: Ring Gear Differential Case Pinion Shaft Pinions Side Gears Drive Shafts Tires Absorption of differential rotation: Self-turning pinion absorb difference in rotation of the side gears (left and right tires). Differential limit: Initial torque The cone springs in a multi-disc clutch imparts axial load in the thrust direction, producing initial torque.
Page 367 TECHNICAL FEATURES DIFFERENTIAL OPERATION Figure 1 shows the conditions when one wheel wants to spin, that is, tries to rotate faster than the differential case. The torque generates a force applied to the flank of the follower dog from the differential case spline, which is then shared between the two face cams by forces on the inclined faces.
