BRAKE ADJUSTMENT
If your brake seems “soft” or if you have to pull
the lever too far to get proper braking power,
you can adjust the brake to restore them.
To adjust the brake and increase braking power:
1. Place the mini bike on the kick stand with
the engine off.
2. Holding the brake mechanism, loosen the
adjusting nut to let the cable slide free.
3. Scoot the adjusting nut and mechanism
toward the front of the bike, up the cable
until it stops, then back off slightly.
4. This will position the brake at just off of contact, so that it will activate
quicker, but not drag when riding the mini bike causing extra wear.
5. Tighten the adjusting nut on the cable.
6. Check that the wheel spins freely when brake is not applied, but the brake
should engage more quickly when riding.
Never ride the mini bike when the brake is not working
properly. If you can not get the brake adjusted and repaired properly, you
may need to replace the brake pads. Refer to your local Motovox Service
Center for assistance.
Your throttle should have some free play to
safely operate. The free play should range from
1/16” to 1/4”. To adjust the free play, follow
these steps:
1. Loosen the lock nut on the throttle cable.
2. Turn the adjuster nut in the direction
needed to gain or reduce free play.
3. Tighten the lock nut.
4. After adjusting, check the throttle for
smooth rotation from open to closed in all
steering positions.

Rear Disc Brake
A corroded spark plug can cause your engine to run rough, or in the case of a
fowled plug, can cause your engine to not run at all. To check the spark plug
it must be removed from the engine. The following steps will demonstrate
this procedure.
Locate the spark plug boot on the top
of the engine toward the front of the
motor. Carefully remove the spark plug
boot by pulling and twisting the boot
housing. Do not pull on the plug wire.
Once you have the top of the plug
exposed, use a 19mm wrench to
unscrew the spark plug out of the
engine by turning counter-clockwise.
Inspect the plug and check to make
sure the gap is set to .030. Using the
chart below, determine if the spark
plug should be replaced. If replacing
the spark plug, use an Autolite 255 or
equivalent spark plug only.
To re-insert the spark plug or to install
a new one, simply screw the plug back
into the hole by hand, turning the plug
clockwise. Tighten with the wrench.
Be very careful not to
over-tighten and strip the threads.
