Advice 1: How to increase speed on scooters

All delivered in our country scooters class 50 CC limited in the speed at 50 km/h. This is a requirement of the SDA. But the desire vladeltsev to make your scooter faster not lost. To achieve higher speed performance in various ways.
How to increase speed on scooters
You will need
  • - aftermarket mufflers, kits and other Chu
Instruction
1
Remove the limiter. The constraints on design are different digital (limit the speed), mechanical (limit gear ratio in the CVT) and the limiters on inlet and outlet (to limit the filling of the cylinder mixture). Of course, there are also combination methods. Electronic limiter hard wired into the switch of the ignition system, and removing it is impossible. One way out – to buy and install a switch with an adjustable Rev limiter or no restrictions. The first type of switch is preferable, since it protects the motor from damage by excessive promotion.
2
Replace the muffler on a scooter. Standard factory mufflers from a semi-sports scooter (Suzuki Sepia ZZ or Honda Dio ZX) will provide a small increase in engine power without increasing the optimal speed, improve filling of the cylinder with the mixture, it will put torque characteristic of the motor. Aftermarket silencers (e.g., LeoVinci SP3) will provide up to 20% capacity increase, will increase the optimum engine speed. The use of such tubes involves tuning the variator: install it with lighter weights and a stiffer return spring.
3
Sport mufflers (LeoVinci ZX) provide an increase of up to 50% of capacity, significantly increase engine speed and require not only tuning of the CVT, but harsher recoil spring centrifugal clutch. Or replacement of the variator and the clutch on the sport models. Thus, the removal of restrictions and the replacement of the silencer is able to raise the speed to 80-90 km/h and to improve the driving dynamics.
4
To further increase the power gain tuning kit for the engine. Renowned firms like Malossi, Polini, DR, Eurocilindro produce for 50 CC scooters kits piston with increased volume. The kit consists of cylinder, piston with rings and a finger, and a new cylinder head. The installation of the kit allows you to raise the engine size to the standard values of 70 and 85 CC with a simultaneous increase in power at nominal or high speed. The most preferred cylinders with coating was nikasil withstand high rpm, providing more power and torque than steel and significantly more durable.
5
To prepare the scooter for a competition install tuning kit piston racing class (e.g. Polini Corsa Kit). Engine power will grow incredibly but will make it unsuitable for everyday use due to moodiness and increased demands for frequent and expensive maintenance. For example, the standard piston rings need to be replaced after 10 thousand kilometers, and the Polini Corsa cylinder Kit every 2-3 thousand.
6
Install the rear gear. Because of the design features of the 50 CC scooters a significant increase in engine power does not lead by itself to increase the maximum speed without change gear ratios. Therefore, the tuning motor must always be accompanied by the purchase of aftermarket kit for the rear gear (e.g., Gear-Kit). When using the kit Gear-Kit and aftermarket cylinder 85 CC standard scooter is able to develop up to 110-120 km/hour. When using the racing kits even more.
7
Do some tuning of the carb. 50waste water scooters are usually installed the carbs with 12-mm or 14-mm diffuser. After you install tuning kits to the engine, replace the carb sport (for example, Dell'orto) with a cone diameter 17 or 18 mm. racing cylinders required carburetor size 22 mm. As a rule, the replacement carb was escorted to the replacement of the surrounding installation components and installation of filter increased performance (zero resistance)

Advice 2: How to increase the power of a moped

Fly with the wind on a small moped or scooter – there's a real teenagers dream. Whatever unit they may have acquired, it always seems that the power is not enough. And because the craftsmen are trying to add in a variety of ways. Some of them are quite safe and convenient.
How to increase the power of a moped
Instruction
1
Start the reworking of the engine by removing the plugs installed by the manufacturer. For the Japanese technology for a start replace the switch - there is the main plug of the most common models. Replacement switch for tuning will remove the restriction on the maximum engine speed that will definitely give boost to maximum speed. Be sure to check the engine for wear of the crankshaft bearings and cylinder-piston, before installing the switch. The new models (made after 2000) often contain plugs in the muffler (catalysts and "whistles") and the variator (washers).
2
Replace the silencer of the resonance pipe that is compatible with your Chu, adjust the transmission.
3
Install the carburetor with the increased diameter of the diffuser. Easy to install and configure are carbs with a diameter of 17.5 mm. Replacing the carburetor, be sure to replace the air filter. There may come a sport filter of zero resistance.
4
Install a sports variator. The belt variator is also best to replace the amplified.
5
Install Chu Sport-class – is perhaps the most radical and effective way to increase capacity. At the same time pay attention to the bearings and crankshaft were in perfect condition, otherwise the increased load will destroy them very quickly.
6
Replace the exhaust system on the sport, the so-called "saxophone", which consists of a resonator, the exhaust manifold and the muffler). Well-chosen saxophone will increase capacity by 10-15% and allow to raise the maximum speed.
7
Better not leave the regular brake. Install disc brakes with hydraulic motors, use reinforced brake hoses, replace brake pads on a sport.

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.

You will need
  • - tuning body kits for your model scooter
Instruction
1
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.
2
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.
3
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.
4
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.
5
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.
6
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.
7
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.
8
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.
9
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.
10
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.
11
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.
Useful advice
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 increase engine power on a moped

To increase the power of the engine on a moped in several ways. To do this, you need to understand for what purpose you need a large capacity. You should know that the more driving horsepower motor, the shorter his life will be.
How to increase engine power on a moped
Instruction
1
Start tuning kuternoga engine with restore design capacity. After the production is always taken into account environmental regulations and the efficiency of the motor. For beginning just remap the carb - this will have a positive power gain. Factory installed mechanisms of the intake and exhaust do not allow the engine to maximum fuel-air mixture, so it can not develop the biggest power, which is capable of.
2
Replace the air filter the same with more capacity, reconfigure the carb, replace the exhaust to a more productive infrastructure. Now the engine can get the fuel / air mixture as much as you can "suck" and rapidly released through a tube from the exhaust gas.
3
Buy or order a retuned electronic engine control unit. After all, the staff of the ECU at the expense of capacity of the engine does not allow him to burn the maximum amount of mixture per unit of time. In addition, he has changed the ignition timing, which helps reduce levels of toxic substances in exhaust gases and reducing fuel consumption, but again at the expense of power.
4
Now replace the inside of the carb for the jet kit. This will typically include nozzles, spray metering infrastructure and metering needle. Note that an important parameter of the carb is the diameter of its cone. Even if you set the carb up to 50 CC, jet kit 124 Cuba, you will only get a huge consumption of fuel and filled the candle. Therefore, by increasing the volume of the engine by 40% and more change the entire carb entirely. Install new, larger diameter of the bushing and diffuser sections of nozzles. In this case, you must understand that will increase the fuel consumption.
5
Along with replacing the carb, replace the flap valve at the inlet. Aftermarket valves are made of carbon fiber and other synthetic materials. They are more rigid and durable.
6
If you increase the cubic capacity of the engine, don't forget to increase the flow area of the valve Windows, otherwise the amount of incoming fuel / air mixture will not increase. The increased volume of the mixture may squeeze into the standard hole of the valve, therefore, it is better, replace the entire "house" on more productive.

Advice 5: How to remove speed limiter on a scooter

Modern scooters are equipped with quite powerful engines, capable of giving the machine a maximum speed of 80 km/h. But to implement the terms of the legislation manufacturers artificially limit the speed at 50 km/h. To remove these artificial restrictions just a basic knowledge and skills in the field of installation and repair of the scooter.
How to remove speed limiter on a scooter
Instruction
1
Often the maximum speed is limited by the setting of the washer between the variator cheeks. This washer prevents the variable speed belt on the outside radius. Sometimes instead of a puck, it sets a special plate from the installation of the weights. To remove a washer or plate, remove the cover and the impeller of the CVT. Puck is removed quite easily. To remove the plate you want to remove and completely disassemble the variator. Simultaneously with this procedure, inspect the condition of the weights and the belt of the CVT. Worn replace. In the absence of washers or plates, they may play a role of a projection on the bushing. Install the new bushing with no lip or grind the ledge with the subsequent polishing of the surface.
2
Installed in the exhaust pipe restrictors are tapered or uniform process that reduces the throughput of the exhaust system. Remove this limiter. When removal of the Appendix requires further sealing of the hole. The use of electric welding desirable. Often in the exhaust system of the scooter is fitted with two stop. For detection and removal of the second limiter, disassemble the exhaust system.
3
Carburetor limiter speed in the form of a special strip on the flap allows you to fully rise. To remove this limiter, remove the cover of the carb. Found the option to install a valve baffle in the float chamber that restricts the flow of fuel in the chamber. Removing it will require knowledge of the device of carburetor to not remove something extra.
4
Electronic limiterinstalled in the switch. Is removed by cutting the blue wire. In the Japanese techniques to remove difficult. Much easier to install aftermarket sport switch off.
5
Non-standard constraints. First, the sleeve on the air filter restricting air flow. It must be removed. Secondly, the closed half the outlet port Chu. The elimination of this limiter is possible with full disassembly of the engine and boring out the window. This is a complex event, in which the means do not justify the goal.
Useful advice
Before removing the limiters check the wear of cylinder-piston group scooter. Otherwise, increase the maximum speed will cause the engine to seize.
Don't try to find the constraints on Japanese scooter, destined for the domestic market of Japan. It simply is not.
