User Manual Radne Motor AB Radne Motor AB was founded in 1967 by Leif Radne to manufacture and sell parts for gokart racing. Approx. thirty years later this is still the business idea of the company, and it is still led by Leif Radne. Radne Motor is today the leading Nordic gokart business. Radne Motor represents the leading manufacturers of tyres, chassis and personal protection, and is also producing the Raket line of engines, mainly for gokart use.
User Manual Raket engines The first Raket engine was introduced in 1972. Extensive research for a reliable, simple to use, yet fun to drive gokart engine at an acceptable price, had convinced Radne Motor to start the manufacture of such an engine. Power chain saw engines are the toughest two stroke engines that are built, and Radne Motor decided to build the gokart engine on well-tested vital parts. Hence, cylinder and piston, crankshaft, carburettor and ignition system were purchased.
User Manual Safety precautions The Raket 120 engine is intrinsically a very safe design. If you follow these rules and general rules for machine safety, you should not encounter any risks or hazards. 1.Always equip your engine installation with a safety switch, which will make emergency stop possible from where the engine is normally operated. 2.Always protect rotating parts with protective covers. 3.Never machine any rotating parts.

User Manual How to install the Raket 120 engine in a chassis or frame For the assembly of the Raket 120 engine four threaded holes, M8, are provided in the bottom of the crankcase. For mounting the engine in a kart, a special mounting plate is available (part No 3004) with mounting clamps (part No 3005), which facilitates the assembly as well as the adjustment of the chain tension. Note, the correct length of the M8 bolt is important. The depth of the threaded hole is 20 mm.
User Manual The carburettor The Raket 120 is equipped with a Walbro diaphragm carburettor of type VG6 with fixed High Speed jet. How it works The carburettor is connected to the fuel tank with a flexible hose, made of rubber or plastic. The hose connects to the fuel inlet nipple (part No 32029 - see figure). When you pull the starter rope and the piston moves up and down the cylinder, the pressure variations in the crankcase makes the pump diaphragm (part No 32045) move up and down.
User Manual as the choke. The purpose of the choke is to enrich the fuel during start by restricting the air flow and increasing the vacuum in the venturi. When you intend to start your Raket engine, you normally close the choke and pull the starter rope. After one or two pulls the engine will start. As the fuel-mixture with closed choke is very rich, the engine will normally stop soon. Then you open the choke, open the throttle a little and pull the starter again.
User Manual Air filter It is strongly recommended that the Raket 120 engine is equipped with an air filter. Radne Motor has a number of different designs which all protect the interior of the engine from being damaged by sand, dust and other hard particles. See main catalogue, i.e. inlet silencer No 5201.
User Manual Ignition The Raket 120 engine is equipped with a solid state ignition system, which consists of a minimum of parts. · · · The ignition coil with built in electronics. The flywheel with the permanent magnet. The emergency breaker = stop button. When the flywheel rotates past the ignition coil, an electric current is generated.
User Manual fore you examine the spark plug, the centre electrode may be dark brown or even black. For all the different applications that the engine has been tested for, the recommended spark plug Nippondenso W22MP-U has proven to be the best, and no ”hotter” or ”cooler” plug is recommended. The normal service life of a spark plug is 200 - 300 hours. However, we recommend that you have extra spark plugs available, as e.g.
User Manual The magnapull rope starter When you intend to start the Raket 120 engine, you close the choke of the carburettor and push the decompression valve. Then you should remember two simple rules: never just pull out the rope. Grab the rope handle and pull out the rope slowly until you feel that the starter mechanism has engaged the engine. Then you pull the rope with a powerful stroke. never pull out the full length of the rope. Test once, slowly, to extend the full length of the rope.
User Manual engine, the clutch shall smoothly start to pull the gokart away. If you look at the X-ray-drawing of the engine, you will see the parts of the clutch. It consists of the hub with three spokes, three powder iron weights and three short springs. These parts are fastened to the shaft of the engine through a coarse counter clockwise (left turn) thread. You will also find the clutch drum with the sprocket wheel for the chain.
User Manual Crankshaft The crankshaft with connecting rod and connecting rod needle bearing is one unit, and we don’t recommend any attempts to repair this unit. The bearings on the crankshaft are SKF 6203 C 3. This bearing cannot be replaced by any standard bearing. (Larger radius of the inner ring). When you disassemble the crankcase, the bearings should normally sit on the shaft.
User Manual Mufflers Raket 120 can be delivered different muffler arrangements. The Power Exhaust Muffler consists of three parts: . the exhaust tube that is bolted to the cylinder . the flexible hose that connects the exhaust tube with the muffler, and . the tuned muffler (with or without emission control) The three parts of the Power Muffler have been tuned to give the best (highest) output, and we advise against the change of any of the three parts.
User Manual Wearparts and service intervals The Raket 120 will need very few spare parts due to its simple and reliable design. The table below shows some typical service intervals. Please notice that the conditions under which the engine is operated will have great influence on these intervals.
User Manual Environmental fuel In some countries fuel for lawn movers, garden tools, chain saws etc is made from other raw materials than oil. The advantage of these fuel products is that they produce less of exhausts that polute the environment. Before you use a fuel of this kind, make sure with the manufacturer that you can do so without harm to your Raket engine.
