modification whatsoever is allowed. The
crankcase halves should both be labelled
with RAKET.
The sealing rings are “open to choice”, in
other words they may be exchanged for
any other factory make of your choosing
under the condition that the model and
the dimensions are kept the same. On
both sides there should be 17x28x7 with
sealing lip as well as dust sealing lip.
Original sealing rings have a sealing lip
that is Teflon coated.
The ball-bearings move on the crank-
shaft but are press fitted in the crankcase
and are original 6203 TN 9C3. It is not
permitted to change the bearings’ fitting or
placement.
2. Crankshaft
The crankshaft may not be altered in any
way. For instance it is not permitted to
balance the crankshaft by removing or
adding material. The same applies to the
connecting rod, in other words no altera-
tion of any kind is allowed.
The needle roller bearings at either end
of the connecting rod are open to choice
with regards to factory make as long as
the same model is used. This should be
needle roller bearings in a steel basket.

8. Product description for ho-
mologation purposes
Raket 95 will be homologated in those
countries where it receives approval from
the local Automobile Sport Federations.
This product description may not be
used as a supporting document during
technical control unless the appropriate
Automobile Sport Federation’s stamp of
approval exists.
The main principle involved is that abso-
lutely no changes or modifications may
occur. The engines should be “out of the
box”, in other words exactly as they are
delivered. Below follow some clarifica -
tions.
1. Crankcase
The crankcase should have the same
design as shown in the picture.
The measurements that are of decisive
importance are those relating to the part
of the crankcase that exactly encloses the
crankshaft. In this matter absolutely no
The cylinder should be completely original
and absolutely no modification is allowed.
For instance it is not permitted to smooth
out the edges of the transfer ports.
The cylinder should be labelled MAHLE
56 ZK3 and display Radne Motor’s logo
and article number 35085. No other labels
are permitted.
Exception:
If a thread in the cylinder were to be dam-
aged, for instance the spark plug thread,
then it is permitted to make the repair
with a thread kit of the Heli Coil variety.
PLEASE NOTE! It must be the same
thread as the original.
4. Spark plug
The original spark plug is NGK BPM8Y,
but it may be exchanged for another
equivalent factory make. The diameter
of the thread and the thread length, 14x
9.5 mm, must always be the same as the
original.
5. Piston
You may not change to another factory
make of piston and it is very unlikely that
you will come across any pirate versions
of pistons.
The piston should be labelled on the top
with R 35087.
Piston pins, piston pin locks and piston
rings must be original.
On the top of the piston there is an arrow
indicating which side of the piston should
be facing the exhaust port.
6. Carburettor
The carburettor is a Tillotson HS 319 A
carburettor. Absolutely no modifications
whatsoever are permitted. The venturi
diameter should be 17.7 mm and the
