Start with the engine. The heart of any moving structure is an engine and it is more powerful and more reliable, the faster will be the scooter. Borrow the engine from the motorcycle. They are similar in design and fit you weight. Of course, we are not talking about the big liter monsters, and about 125 and 250 CC depending on the size of your scooter.
Adjust the body of the scooter. Very often owners of Japanese higher quality scooters regret not bought only for the reason that cheaper models often look better. As the motorcycle plastic scooter can be custom made or buy ready-made option. Visit the online store specializes in your model of scooter or try a search in the city garages. In any case, you will be able to find the option that suits you covering a scooter.
Do airbrushing. Your scooter was reborn, and it is time about it to loudly say. Refer to the workshop by drawing or buy a set of stickers. It is better to choose the first option. You can together with the master to come up with original design that will not be stereotyped and will set you apart from the crowd.
Remember that with the replacement of the engine more than 50 cubic meters, you will have to have the right category.
Advice 2 : How to make a scooter faster
In the life of each owner scooters comes the hour when the maximum speed and the dynamics required more. If the scooter is for the owner to stand out from the crowd, the camera just has to hit all the speed. But only the right approach to the tuning of the scooter leads to the desired result. Although it often makes more sense to change the scooter for a more powerful than my old tune.

After completion of the running scooter can remove the limiters of the maximum speed. Without it, the speed will increase to 80-90 km/h. It is the most affordable way to increase the maximum speed.
Options inexpensive tuning kuterevo first, change the muffler scooter tuning resonant pipe suitable for cylinder-porshneva scooter group (tspg) or on the muffler with the "torque" issue. For the first option will suit pipe Laser X, ZX LeoVince, Technigas Next. For the second – Polini No Smoke, LeoVince SP3/Turing, Technigas Silent Pro. In combination with the setting of the transmission in accordance with the parameters of the new exhaust, this will give an increase of 10-15 km/hour.Second, change the carb on the carb with a cone diameter of 17.5 mm as the optimum and convenient to set up. The best quality produces DellOrto carburetors.Thirdly, the replacement of the CVT on the sport. This variable allows you to accurately and efficiently configure the transmission for the new engine characteristics.The most effective way to raise the power and speed of a scooter – sports Chu the increased volume. In addition, for the two-stroke engine increases not only the volume of the cylinder, but also improves the purging process, i.e. it keeps adding more power and speed. The set comes also and cylinder head with optimized combustion chamber. When you install this kit it is very important that the crankshaft and bearings were perfect condition. Otherwise the increased load on these parts will quickly destroy them.
The next stage of tuning scooter – racing. It is costly, resulting in easier to buy a faster scooter than to tune.First, installed reinforced crankshaft with matching bearings and a reinforced rod. Only such parts of the engine will withstand shock loads, will help to realize high power, ensure stable and reliable operation of the engine.A high rpm racing engine (up to 10,000 Rev/min) require appropriate reliability of nodes, which is not able to provide factory parts. The diameter of the carburettor must be at least 17.5 mm, to provide power racing engine. Carb setting should provide good mixing at high speed. The best option – carburetor 19 mm in combination with a sports air filter.Other racing tuning procedure is repeated as described in claim 2, all the components are more qualitative and productive. For example, it is recommended to install variator Polini Evo or Malossi OverRange.Racing scooter have high dynamics and maximum speeds (far beyond 100 km/hour) and is able to satisfy many fans of high speeds.
Peak boost tuning Hi End. It allows you to shoot up to 3 HP for every 10 CC of engine displacement. Manufacturers of kits for the tuning of this level Malossi, Polini, Kunda, 2Fast, Fabrizi, MetraKit. Elite components and prices are appropriate.Engine this level develops up to 20,000 Rev/min About the efficiency of the question: the engine is tuned most effectively to work out for two 15 minute race session and a few training hours. Then the engine requires revision with replacement of worn parts. Installation tuning sets requires a major rework of the engine and the chassis of the scooter. Can not do without a rotary ignition, it allows not to lose the power of the spark at high revs. Installing this feature will require you to abandon the entire electrical scooter, not related to the ignition system. The ratio of the reducer is determined experimentally.Such scooters can go the distance of 400 m over 12-14 seconds to start. Resource rings is 1500-4000 km when used for everyday driving. Use only 98 octane gasoline, with the highest quality and not one that they sell at gas stations. Oil is poured only very expensive.
Almost all the sets of tuning scooter is designed for self-installation. However, the more expensive the purchased kit, the more it is recommended to install it in a specialised workshop.
Advice 3 : How to increase engine power on a scooter
Many owners of scooters with time starting to run out of the standard engine power. Want more speed, more acceleration, more reliable and precise movement with heavy loads, rough roads and climbs. Add horsepower to the engine of the scooter is quite possible on their own.

Start with restore design capacity. The fact that the factory settings of the motor is made subject to environmental regulations and improve efficiency. Reconfigure the carb – this may be enough for a noticeable increase in power. Replace the air filter on the model with increased capacity and the exhaust system more efficient. This way you will remove the obstacles that prevent the engine to develop full power, which he's capable of.
Look in the sale or order a retuned electronic engine control unit (ECU). By removing the electronic speed limits and changes the ignition timing with the help of this device the motor has reached the maximum design capacity. This will worsen fuel economy and increase the content of harmful substances in exhaust gases.
The following steps increase the power proportionally will reduce the resource of the motor. For example, boosted to 20 HP engine with engine displacement of 50 cubic centimetres will be online for 1-2 race session. Decide for yourself: do you need such sacrifices.
Modify power supply system. To do this, find your carb tuning kit with a set of nozzles that spray the main metering system and a metering needle. When installing this kit to replace or hone the diffuser below the increased diameter. Without increasing the diameter of the diffuser increase the power will not.
To increase engine power by more than 40% replace the carb entirely. Tuning the carb already has the desired diameter and cross section of the nozzles. Note that with such a carburetor, the fuel consumption will rise by more than half.
On a two stroke engine with carb and replace the flap valve at the inlet. To obtain the effect of the tuning flap valve must increase and the flow area of the inlet window of the valve. Not to rastakat them yourself, make replacement housing flap valve to a more efficient aftermarket model.
When upgrading the carb or installing a new, be sure to replace the air filter. The best option would be a sport filter of zero resistance. Their cost is very high compared to the standard, but they are reusable. Every 400-600 km rinse them in gasoline and treat with special oil.
Install a sports exhaust system. The qualitative tuning system should have the exhaust manifold, resonator and muffler. Properly chosen and installed system will not only increase the capacity by 10-15%, but increase the maximum engine speed and shift the peak power in the higher revs.
Put a sports version of the ECU. At the same time pay attention to its settings. Racing ECU, as a rule, are set to develop maximum performance at high rpm. Such models give a good advantage on the racetrack, but impede the operation of the scooter in the urban driving mode. For everyday use way control unit with software tuned to low and medium revs.
Expensive model ECU have the ability to change recorded in this program. This requires a computer, interface cable, software and appropriate skills. If there is no knowledge and experience for the selection of a suitable program control, don't try to do it the experimental way. Find a UNIT with several modes of operation.
ECU with a factory several management programs have on the power button, switching programs on the fly. The result of the capacity increase will be lower than on programmable models with careful selection of computer programs, but for city driving this system is quite convenient.
Tuning kits - the result of work of many engineers and is based on computer programs. Do not attempt to "improve" them.
Advice 4 : How to boost scooter
Scooter is a compact and convenient means of transportation, has firmly taken its place in the transport stream of the country. However, in order to increase the comfort of the ride, it makes sense to increase his power, luckily there are a lot of possibilities. Improved dynamics not only increases the fun of a scooter, but also allows to significantly increase driving safety.
You will need
- - set of keys
- - abrasive paste
- - the piston and the shirt of the cylinder of larger volume
- - exhaust pipe
- - belt CVT
- - spark plug
Replace the cylinder-piston group for tuning larger. The result is the displacement of the engine increases, and this will allow to achieve substantial power gains at a minimum cost. In addition, offset by the effects of improper break-in. Together with the replacement of Chu should change the spark plug.
Polish the crankcase, the combustion chamber and the bottom of the piston. This set of measures allows to increase the filling of the cylinder fuel-air mixture and improve the combustion conditions. Power gains will not be large, however, the scooter will become much sharper to respond to the throttle.
Adjust the carb. To ensure the most effective use of increased, need to retune the carb by installing new nozzles and polished diffuser. Standard air filter ensures a long service life, but it does not allow the engine to "breathe", it is necessary to change the filter of low resistance.
Change the exhaust system. Now available a large number of sport exhaust systems for scooters. The most efficient way – the installation of the resonance of the exhaust pipe of a type of "saxophone". You should achieve the most complete coincidence of the outlet port Chu and the receiving hole of the pipe. In addition to increased by 10-15 km/h maximum speed of the scooter will also please the owner a "sporty" sound while driving.
Reconfigure transmission. After all of this work, the scooter engine will be more powerful, standard and reducer will not fully meet its requirements. So you need to lengthen the gear ratio by 12-20%. This will allow to dramatically increase the maximum speed. Installing the sport weights in the variator and belt replacement will have a smaller, but also very tangible effect.
Remove the limiters. All the efforts may be futile, if the scooter includes a speed limiter. The most common form of restriction is the restriction in the switch. Consult an electrician will solve this problem.
