- Or sports tuning parts
To tune a moped at the most budget level replace the variator weights, remove the speed limiter and standard hone the cylinder under the piston with a diameter of 47 or 44 mm. Weights can be bought at any parts store or make your own. Cylinder bore trust professionals. The total cost of the tuning will be about 1000-2000 rubles. When the cylinder bore 44 mm moped will start to develop 65 km/h, in bore up to 47 mm up to 70 km/h. The acceleration will be improved, engine life is almost not affected.
For tuning a moped at the average price level of the standard, replace the piston and 50 CC piston in greater capacity (for example, 72 cubic cm), install a sports variator. Compared to the above tuning of the engine to decrease, and the rate is likely to reach 70 km/h, mainly due to the increase in gear ratio of the CVT.
For expensive tuning of moped, replace the piston to 80-cubic or hone the cylinder under the piston is 50 mm, install the cylinder head with increased valves and a sports variator. In addition, buy tuning the carb or adjust the old the jet at an increased. If desired, put Shirokovsky camshaft. At this level of tuning speed is 75-80 km/h, engine life is reduced a bit (especially the crankshaft bearings). There is an opportunity to move with the slipping and "porpoise".
For maximum tuning completely redo the engine. Install the piston 90 CC (bore 52mm), head with enlarged valves, a sports variator, brand cylinder group, a sports variator. Put the carb from a light bike 125-150 CC or sporty tuning. Be sure to put brand Shirokovsky camshaft, reinforced or sport crankshaft. As a result of these changes, the engine life will be reduced, the dynamics becomes comparable to that of 125-150 CC bike, the speed reaches 90 km/h. Don't forget to set the air intake to the cooling system, to supply cooling oil to protect from overheating.
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.
You will need
- Scooter and acquired sets of tuning.
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 make a moped
If you have to ride your bike long distances, then you may wonder about how to rig a motor and thus make the moped. This will be able to go without exercise and at the same time, all the benefits of the bike – the lightness, the mobility, the lack of age restrictions.
You will need
- - Bicycle;
- - petrol or electric motor;
- the moped used;
- - pulleys;
- - the drive belt;
- - fastening elements;
- - headlamp;
- electric wires and switches;
- - brake light.
Take an old bike and test it for reliability. Note that the motor immediately increases the load on all parts of the bike, so everything should be fine. Lubricate all moving parts, adjust the chain, cassette, rear bushings, brakes, tires, derailleur cables and other important details if necessary.
Pick up a motor for mopedand. You can use the motor from an old mopedand petrol lawn mowers or chainsaws. Before disassembling the motor, test it for performance, but also on the noise level (in any case, the singing of the birds you already can't enjoy). Also, pick the engine capacity of the moped with motor 1 HP, most likely, will not be able to move independently, and a roller coaster will have to help him with the pedals. More powerful engines more comfortable but also heavier.
Install on the rear wheel driven pulley, which will transmit rotation from the motor to the wheel. To do this, take an ordinary Bicycle rim slightly smaller than your rear wheel (2 inches or 6 cm), well his fix so that it rotates with the wheel.
On the bike frame under the seat make some extra tubes and a metal stand made of sheet steel in order to accommodate the engine. Install the gas tank on the top tube of the frame. Weld or fasten the engine to the bike with clamps. If the design allows, set the engine at the rear, on the trunk of the bike.
Connect the motor with a pulley with the timing belt. Inspect the belt before you install it will have to withstand heavy loads.
Given the new features of your old bike, you will probably need a new seat. Make it out of plywood, foam and upholster leatherette with furniture stapler. Then secure on a mopedE.
Be sure to equip a homemade moped front headlight and brake light in the back, because with the purchase of a mopedand you turn into a full-fledged participant of the road.
Advice 4: How to repair a moped
A moped, like any other technology, eventually breaks down. And then the owner faces the choice: buy a new vehicle or fix the old one. It all depends on the nature and extent of the damage. If they are small, it makes sense to make repairs on their own.
You will need
- Wrenches, screwdrivers, awl, vise, hammer and tongs.
Inspect your faulty moped and determine which parts need replacement or repair. New best to book in a workshop or in a specialized store. For details, don't skimp – they many times pay for itself in the future, moreover, depends upon the quality of your safety on the road. Invite your more experienced friend to help you repair.
First, thoroughly wash and dry your bike. Remove elements that will prevent you in the process of repair. If damaged parts have small sizes, it makes sense to include them on the table – so it will be much easier to deal with them.
Detaching separate elements of a moped, remember their sequence. Don't forget that ultimately the entire design will have to collect back. Dismantled parts in clean gasoline or wipe with a cloth soaked in it. Start to disassemble with the front wheels, the boot and racks. Inspect even the smallest items that may affect the performance of the bike.
If the item is badly rusted or has visible defects - chips, curvature, dents, without hesitation replace it. It won't last. After you have all carefully examined and removed the damaged part, carefully lubricate every detail.
Assemble the design in reverse order, instead of the old parts, put new Try not to forget even the smallest details – they are no less important than those same wheels and the steering wheel. It is better not to stretch the repair for a long time, if possible, do everything in a day or two. Otherwise, it is easy to forget something or to lose small parts.
These tips can help only in case if the damage has affected only certain parts of the rack. If you have, for example, "flew" the motor to fix it yourself you are unlikely, and a visit to the salon will become inevitable.
