GENERAL INFORMA TION 1-3 Before Servicing Arrang emen t and Clea ning of Re moved Pa rts Disassembled parts ar e easy to confuse. Arrange the parts accor ding to the order the parts were disass embled and clean the par ts in order prior to assembly .
1-4 GENERAL INFORMA TION Before Servic ing Tight ening S equen ce Bolts, nuts, or screws must be tight ened according to the specified sequence to pr event case warpage or deformati on which can lead to malf unction. If the specified t ightening sequence is not indicated, tighten the fasteners alt ernating diagonally .
GENERAL INFORMA TION 1-5 Before Servicing Pres s For items such as bearings or oil seal s that must be pressed into place, apply small amount of oil to the con- tact area. Be sure to maintain proper al ignment and use smooth movements when install ing.
1-6 GENERAL INFORMA TION Before Servic ing Directio n of Engine Rot ation When rotating the crank shaft by hand, the free play amount of rotati ng direction will af fect the adjustment. Ro- tate the crankshaft to positive direct ion (clockwise vi ewed from output side).

16-20 ELECTRICAL SYSTEM Precautions There are a number of important precautions that ar e musts when s ervicing elect rical systems. Learn and ob- serve all the rules below . ○ Do not reverse the batter y lead connections. This will burn out the di odes on the electrical parts.
ELECTRICAL SYSTEM 16-21 Precautions Male Connectors [ B].
16-22 ELECTRICAL SYSTEM Electrical Wiring Wiring Inspection • V isually inspect the wir ing for signs of burning, fraying, etc. If any wiring is poor , replace the damaged wiring. • Pull each connector [A] apart and inspect it for corrosion, dirt, and damage.
ELECTRICAL SYSTEM 16-23 Battery Battery Removal CAUTION Do not disconnect the battery cables or any other electrical connect ions when the ignition switch is ON, as this could damage t he ECU (Electronic Con- trol Unit). Never reverse the connections of the battery , this could damage the ECU.
16-24 ELECTRICAL SYSTEM Battery CAUTION Do not remove the aluminum seal sheet [A] sealing the fille r ports [B] until just before use. • Check to see that ther e is no peeling, tears or hole s in the seal sheet on the top of the battery . • Place the bat tery on a level surface.
ELECTRICAL SYSTEM 16-25 Battery • Fit the seal cap [A] tightly into the f il ler ports until t he seal caps are at the same level as t he top of the battery . NOTE ○ Do not hammer . Press down evenly w it h both hands. CAUTION Once you installed the seal caps aft er filling t he bat- tery , never remove it, nor add any water or el ec- trolyte.
16-26 ELECTRICAL SYSTEM Battery Precauti ons 1) No need of topping–up No topping–up is necessary i n this battery unti l it ends its life under normal use.
ELECTRICAL SYSTEM 16-27 Battery Interchang e The sealed batter y can fully displ ay its perfo rmance only when combined with the pr oper vehicle elect ric system. Therefore, replace a sealed batte ry only on a motorcycl e which was originall y equipped with a sealed battery .
