Advice 1: 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
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).
Replace the silencer of the resonance pipe that is compatible with your Chu, adjust the transmission.
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.
Install a sports variator. The belt variator is also best to replace the amplified.
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.
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.
Better not leave the regular brake. Install disc brakes with hydraulic motors, use reinforced brake hoses, replace brake pads on a sport.

Advice 2 : How to vulcanizing chamber for moped or scooter

Vulcanization chamber of a moped or scooter is more serious process than simply sticking the patch. So that the wheel is not pulled at the most inopportune moment, is to follow the simple technology of vulcanization.
Cold vulcanization
Once the camera is removed from the wheel, it is necessary to determine the fault location; to do this, inflate the removed camera and visually locate the puncture. If it immediately fails, then you can immerse it in a suitable container; the escaping air bubbles indicate defective area. In order not to lose the puncture, plug it match. Conventionally, the curing process can be divided into 2 types.


You will need a special kit for attaching patches, fine emery paper, any degreasing liquid and rolling (roller) to press the glued patch. Position the camera on a flat, comfortable place, take a match and determine the location of the future patches to pick her up from a set of size (overlap damage from all sides should be about 1.5 cm). Take fine sandpaper and carefully apply on the area around the damage. Now clean whitened place with a solvent, wait for it to dry, and apply a thin layer of glue.

Until it dries (3-4 minutes), prepare the patch, removing it from thin layer of the protective film. Now apply the patch on the damaged area, being careful not to touch the hands of the puncture site and secure it by pressing the center and edges. In conclusion, roll the patch with a suitable knurling roller. Such repairs are carried out with quality materials that will allow the scooter to travel thousands of kilometers. However, there are more reliable repair method to successfully glue the camera not only mopeds but also trucks.


This is a more reliable method, requiring the availability of raw rubber and vulcanizer, which can be electric or marching (running on gasoline). Crude rubber similar to normal, but the touch is more soft, supple. Once you've identified the place on the camera, Stripping and abasiri it, take any piece of raw rubber and put in gasoline for 3-5 minutes. When the patch will swell up and apply it to the puncture site and cover with paper so that the camera does not touch the soles vulcanizer.

The resulting "hamburger" hold in already-heated device. The cure time of the camera for a scooter is about 5 minutes. More precisely, can be calculated according to the formula, by multiplying the thickness of the camera in millimeters in figure 7. When the time is up, let cool vulcanizer, then remove paper and sprinkle the patch with talc to the tire from sticking to the camera. It remains only to check the quality of curing, inflate the chamber to the elastic state and lowering it into the water. The lack of bubbles suggests that everything is done correctly.
