3. Instructions for mounting 

the Raket 95 engine onto the 

kart.

The process for mounting the Raket 95 

engine onto your kart can of course vary 

somewhat depending on what type of kart 

you have. Below we provide some advice 

and guidelines that are normally appli-

cable to most types of karts.

1.

The Raket 95 engine is designed to fit di

-

rectly onto the engine support that already 

exists on your kart. You will need four M8 

Allen (hexagonal) bolts in order to attach 

the engine to the engine support.

2.

Your engine has an engine sprocket with 

11 teeth. It is normally a good idea to try 

an 80-tooth sprocket on the rear axle, 

but then it is of course up to you to test 

different settings for different tracks. A 

curvy track may require a larger sprocket 

= more teeth, while a straight and long 

track may require a smaller sprocket on 

the rear axle.

3.

The great majority of karts have a holder 

for the silencer as standard, and the ac-

companying silencer is suitable for use 

with such a standard holder. It comes 

with three springs that hold the silencer 

against the engine’s exhaust pipe, and it 

will require two slightly longer springs to 

hold the silencer in the support, for which 

you can use the kart’s standard springs. 

4.

A holder for the throttle cable can be 

found between the carburettor and the 

carburettor flange, while a lever with a 

holder for the cable can be found on the 

throttle shaft.

5.

You need to have a CIK-approved inlet 

silencer to be able to drive and race your 

kart. There are several different models 

available and all are suitable for use with 

the flange on the inlet crown. 

6.

How you will then fasten the inlet silencer 

to your kart depends on the type of inlet 

silencer that you have chosen. We recom-

mend that you are careful when it comes 

to fastening the inlet silencer since this 

normally is required to absorb quite hard 

knocks. We can certainly recommend 

the use of Radne Motor’s holder (article 

number 5208).

7.

When it comes to mounting the battery, 

battery box and the connection between 

the battery and the starter motor, a de-

scription of how to do this can be found in 

a separate section of this manual.

4. Starting and stopping the 

Raket 95 engine.

Thanks to the Raket 95 engine being 

equipped with an electric starter it is nor-

mally very easy to start. No longer does 

one need a strong mechanic who is able 

to lift the rear end of the kart in order to 

run-start the kart.

1.

Make sure that you have filled the tank 

with fuel.

2.

If the fuel line is empty of petrol then take 

away the inlet silencer if it is attached, 

hold your hand over the carburettor and 

give full throttle. Press the start button 

and hold it in until you can see that the 

fuel is being pumped to the carburettor. 

Release the start button.

3.

When you start the engine you should 

not apply the throttle, but hold the brake 

pedal down in order to avoid the kart from 

beginning to roll when the engine starts.

4.

Push the start button. Normally the engine 

will start directly. As soon as you hear the 

engine ignite you should take your hand 

away from the inlet silencer.

5.

If the engine happens to stop then press 

the start button again. However this time 

you should not hold your hand over the in-

let holes on the inlet silencer. If the engine 

does not ignite and start directly, you can 

carefully try to give a little throttle. This 

may be required in particular if the engine 

is cold, but otherwise there is a risk that 

the engine will receive too rich of a fuel 

mixture. 

6.

If you do not succeed in starting the 

engine through the method described 

then you should check the starter bat-

tery. The battery maintains its voltage as 

long as it is charged, but when it begins 

to approach the limits of its capacity the 

voltage can reduce quickly. Low voltage 

leads to less revolutions for the starter 

motor and thus can cause problems 

starting, especially when the engine is 

warm. A fully-charged battery will normally 

cope with 50 starts before it needs to be 

recharged. 

7.

You stop the engine via the short circuit 

button that can be found on the battery 

box.
