Never allow contammiinnaatteess (dirt,. water, etc.) to get into ann open reservoir.
* Once the hydraulic system hass beeenn opened, or if the brakee feels spongy, the system must bee bleed..
• Always use freshh DOT 3 or 4 brakee fluid fromm a sealed container when servicing the system. DDo not mix different

types of fluidd they may not bee compatible.

CAUTTIIOONN::

NOTE:
If air is entering the bleeder from around the bleedd valve
threads, seall the threads with teflon tape.

Close the bleeedd valve and operate the brake lever (pedal).
If it still feels spongy, bleed the system again.

If a brake bleeder is not available, use the following pro-
cedure:
Pump up the system pressure with the brake lever (pedaall))
until lever (pedaall)) resistance is felt.

11.. Pump the brake lever or pedal several times, then
squeeze the brake lever or push the brake pedal all the
way and loosen the bleed valve 1/2 turn. Wait several
seconds and close the bleed valve.

NOTE:
Do not releaasseethe brake lever or pedal until thea bleed valve

* Always turn off the ignitiioonn switch before disconnecting any electrical components.

CAUTTIIOONN::

Soommee electrical commppoonneennttss may be dammaaggeedd if terminals or connnneeccttoorrss are conneecctedd or discoonnnneecctt whilee the
iganition switch is OON and aa current is pmresent.

* For extennddeedd storage, removvee the battery, give iita fuull charge andd store iittinna cool, dry space. For maximum service
life, charge the storedd battery every two weeks.

* For battery remaining inn a stored motorcycle, disconnect the negative battery cable from the battery terminal.
The battery cann bee damagedd if overcharggeedd or undercharged, or if left to discharge for long periods. These same
conditions contribute to shortening the life--ssppaann of the battery.. Eveenn under normal use, the performance of the
batteryy deteriorraatteess after 2--33years.

- Battery voltage may recover after battery charging,, but under a heavy load, batterryy voltage will drop quickly and

eventuallyy the battery will bee completely discharged. For this reason, the charginngg system iss often suspectteedd to be
the problem. Battery overcharge often results inn problems innthe battteerryy itself, whichh may appear to be an overcharge

msymptom. If one of the battery cells iss shortedd andd the battery voltagee does not incrreeaassee,, the regulattoorr//rreeccttiiffiieerr

. supplies excess voltage to the battery. Under these conditionnss,, the electrolyte leveell drops quickly.
Beforree troubleshooting the charginngg system, check for proper usee andd maintenance of the battery. Check if the
batteryy is frequently under a heavy load, such as havingg the headlight andd taillight ONN for long periods of time

- without ridiinngg the motorccyyccllee..
The battery willl self-discharge when the motorcycle is not usee.. For this reason, charge the battery every two weeks

- to prevent sulfation from forming.
When checkkiinngg the charging system, always follow the stepss inn the troubleshooting flow chart (paggee 17-31)..
Alternator servicinngg cann bee done with the engine inn the frame.
