INTRODUCTION
Minibike 2,5 is intended for a drive on closed tracks with even, smooth, and
dust-free surface. Both growns - up and children can ride on the Minibike.
Children only under the supervision of a grown - up and responsible person. If
the terms of a track are fulfilled, the Minibikes can be used for races. Minibike
Blata should not be used during winter season and under bad weather
conditions. Usage under these conditions leads to abnormal mechanical wear
and corrosion of most minibike parts - especially those directly exposed to
climatic influences. Beside that, riding under these conditions increase the
risk of injury or health damage.
Minibike is equipped with a single - cylinder, two - stroke, petrol combustion
engine, with a front and rear disc brake, the rear one being controlled by a
lever on the left side of handlebars and the front one by a lever on the right
side of handlebars, when seeing in the ride direction. The fuel quantity
controlled by a handle on the right side of handlebars. The engine is fitted with
an air filter and a exhaust silencer. The driving moment transmission from
engine to the driven rear wheel is carried out by a chain drive the ratio of
which can by changed to a small extend by a sprocket wheel exchange on the
rear wheel.

UNPACKING AND BASIC CONTROLS:
The Minibike is packed and delivered with folded handlebars and levers
mounted on them. After unpacking, set up the handlebars in such a function
position that will suit you best. However at maximum handlebars turning, the
brake levers must not bump into the lining. After setting - up the handlebars,
tighten the nuts 1 on handlebars sleeves, the brake levers 2, and acceleration
handle 3 acc. to Fig. 1.At tightening, don´t use an excessive force in order not
to damage the parts or threads, or to distort the tubes, and the like. Verify the
smooth and perfect movement of operating bowden cables of acceleration and
both brakes.

SAFETY
Minibike is not allowed to be used on public roads, as it doesn´t comply with
valid Safety Standards. It is forbidden to ride even where the traffic of larger
vehicles is possible. Minibike is intended for a drive on closed tracks with
even smooth and dust-free surface.For your own and other people´s safety
keep all advices and recommandations, how to use your minibike in a correct
and thoughtful way. serious injuries can result from unsafe operation of this
and other vehicles. You have to minimize the risk by wearing Safety
Equipment e. g. : safety helmet, goggles, gloves, guards of elbow and knees,
firm footwear.
BEFORE STARTING
Regarding the engine life time it is important the minibike to be well run - in as
this fact will manifest itself by the power output and life of engine. The
minibike is considered to be run - in after consuming five full fuel tanks by
riding. For brake-in period we use mixture of petrol and 2-stroke synthetic oil
in the ratio 30 : 1. After brake-in the petrol octane no. 91 or higher and 2-stroke
synthetic oil are mixed in ratio 50 : 1. Mix up throughly the mixture of fuel and
oil before pouring it into the tank. During brake-in don´t increase the engine
speed to maximum and don´t allow the overheating. Check the tire inflation
which should correspond to the driver ´s weight. The pressure in one wheel
has not to exceed 2,5 bar in the front and rear wheel.

STARTING THE ENGINE
To be done only on the starting stand - Fig. 2. After opening the tank filling
hole, fill the tank with fuel and close it by screwing - in cap.Open the petrol
supply cock by turning the small lever into position “ON”, Fig.3. Set the choke
lever into position “C” , Fig. 3. Without turning the accelerating handle, pull
gently twice the starting wire and by next quick pull start the engine. It is not
allowed to pull the starting wire up to full winding off. After a short engine run,
put the choke lever back to position “A” and let the engine run about 1 min.
Let the Minibike on the larking stand and, if need be, adjust the no - load speed
to such a rate lest coupling should take along the no - load speed to such a
rate lest coupling should take along the rear wheel. For adjustment use the
adjustment screw No. 4 on the carburetor, Fig. 3.

RIDE
After mounting the Minibike and slow turning the acceleration handle, you are
starting your ride. Before braking, turn back the acceleration handle and
depress slightly the front brake lever and then the rear brake lever. Beware of
the wheels not to get them in skid.
The Minibike engine will be switched off by pusching the red pusch - buttom of
the stop switch on handlerods. After the first half- hour ride it is necessary to
check the tightening of screws and nuts, especially of the engine. Check also
the brake setting.
PERIODIC MAINTENANCE
The periodic maintenance is the best way how to contribute to the machine life
prolongation, ride safety, and cost decrease. In addition, you will be spared
many worries, time and troubles.
A - Before every ride:
1. Check the Cables and efficiency of brakes.
2. Check the lubrication and chain tension settings. The chain free play
should be (5 mm) (.200in) After every ride clean the minibike carefully and
keep it clean. Do not use aggressive cleaning detergents.
3. After 1-hour of use, wash the air filter in air drying spirits and lubricate it
with special oil for air filters.
B. After every 5 hours of riding:
4. Check the tightness of all bolts and nuts. Tighten carefully to prevent
damage to other parts.
5. Wash the air filter in gas and lubricate it with special oil for an air filters to
better catch the dust.
6. Clean carefully the carburetor float chamber.
7. Check the brake pads, the thickness of brake lining cannot be less than 1
mm (.039 in). Review the basic brake adjustment.
8. Check the state of the clutch pads - the thickness cannot be less than 1
mm (.039in).
C - Every time after 10 hours of riding:
9. Check the state of the clutch pads - the thickness cannot be less than 1 mm
(.039in).
CHAIN SETTING:
When setting up the chain attachment of the rear brake reaction catcher and
the rear wheel axle nut 920.011.01. Then tighten uniformly the chain tighteners
on both sides of rear wheel by means of nuts 920.009.01 , Fig. 5. When the
chain is set - up to reguired sag 0,196” (5 mm), tighten the nut 920.011.01 of
the rear wheel. If there is need to replace the chain, check also both chain
wheels. In case they are worn-out, they must be replaced by new ones at the
same time with the chain.
REPLACEMENT OF THE CENTRIFUGAL FRICTION CLUTCH PADS:
After unscrewing two side screws remove the front lining. Unscrew the
fastening screws and remove the chain cover. Release the chain and
dismantle it. Unscrew four screws keeping the cover with drum of the clutch.
Release the engine brace on the frame, shift it out, and remove the whole
cover with clutch drum. By means of pliers draw off the clutch springs and
loosen the pins holding the clutch levers. At the new clutch levers put the
clutch pins and at assembly proceed in a revers sequence and, in the end,
adjust the chain sag.

ADJUSTING THE BRAKES
Small incremental brake adjustment :
Free play at the handlebar lever is
effected by turning the knurled end on the
cable adjustor. This will allow the lever to
be set at the nominal to ¼ inch of free
lever movement.
Basic brake adjusting:
Screw in the knurled cable adjustor at the
brake lever so the cable is in it’s most
slack starting position.. At the caliper,
loosen the nut, No. 3 and tighten the
adjustable bolt No. 4, so the wheel cannot
turn. Back off bolt No. 4 about ¼ to ½ of a
turn and fix it with lock nut No. 3. Do not
use the cable retainer No. 5 for adjusting
the brakes!
FRONT BRAKE PADS REPLACEMENT: FIG.7
At first, screw in the knurled cable adjustor at the brake lever on the
handlebars. Unscrew two screws M5-914.003.01 that hold the brake body on
fork and shift out the brake backwards. Take out from brake body two distance
columns and two columns with coil. Do not loosen the cable retainer! Unscrew
screws M6-914.010.01 and separate both halves of brake body and shift the
worn-out brake plates out. Into the part with operating mechanism slide the
