Many, especially for the first time, when buying a fifty-kopeck scooter, mistakenly believe that the power and speed of their scooters will be enough for them. They honestly think “how much faster is 50-60 km / h and why?”.

Disappointment soon comes - you want more speed. It is after this thought that scooter owners think about tuning. Of course, piston 70 cc, saxophone mufflers, sports variators and so on look very impressive. But not everyone can pay about two hundred euros for the same tuning piston for a scooter worth 400-600 dollars - it looks somehow illogical - it's much easier to immediately take a 70-100 cc unit. So we will try to tell you about the so-called budget tuning of scooters using the Honda Dio as an example, and share our experience in this matter.

To begin with, before complaining about a scooter, you need to make sure that the stock settings are correct, that is, the standard settings. You can be pleasantly surprised by cleaning exhaust pipe scooter, air filter by adjusting the carburetor and adjusting/reconfiguring the scooter's CVT.

The first thing you can (should :)) do after buying a scooter is adjust the carburetor; and after proper break-in of the scooter, remove the speed limiters. The scooter then becomes faster. Perhaps these are all operations to increase the speed for the first season.

By itself, such a filter will give little (except for the appearance and sound). After installing it, you need to reconfigure the scooter carburetor. It starts to become poorer (there is more air, the same amount of fuel) and this can lead to burnout of the piston. Here you need to conjure with a jet. You can drill it out. You can’t do this on your knee, you need a special tool and an experienced turner. You can drill out the thread and put a jet from Solex. They say from Weber fit without alterations. And finally, you can order it. Price approx. 1.5-2.5 euros. Of course, you can still put carbon petals on the Dio, but this makes little sense if the tuning is not so serious.

With the intake, it seems, while we figured it out, it's time to move on to the release. The simplest thing is just to clean the exhaust pipe. Here you can do it differently. Someone advises walking on the muffler with a blowtorch; someone cut it at the seam, clean it and weld it again. After this simple operation, the scooter will become more cheerful.

So, for now, that’s all about the release, let’s move on to the piston. Everything is simple here, if the compression is 8-10 atm. - everything is fine, if it is lower, it may be necessary to change the rings (or the entire CPG). It is not advised to put Chinese piston rings for three hundred rubles, such savings can lead to the replacement of the entire CPG.

It is recommended to polish the Honda cylinder head, as well as the top of the piston. No soot - more power. It would also be nice to walk through the windows with a polishing machine (Attention! In four-stroke engines, when cleaning the cylinder head, you should not forget that you cannot clean the valves with sandpaper or a metal object at the point of contact with the head body - this will lead to "repressurization", and in the end as a result, to burnout of the valves).

Well, a little about honda variator Dio. Just put new weights - nominal, often heavier weights are put in the factory. Before installing them, it would be nice to walk the grinder along the weight tracks and lubricate them with a thin layer of graphite grease.

Outcomes - scooter Honda Dio, capable of confidently accelerating to 70-75 km / h and sometimes even more, equally well pulling one person or two. And, perhaps, the most important thing is the costs, or rather almost their absence (you can make the filter yourself, dig out the jet in my father's garage)! If you are not preparing your scooter for serious racing, but just need acceptable top speed and traction, then I think this is what you should do.

Used material from www.moto.ironhorse.ru

Many bought scooter Honda Dio are confident that a speed of 50 km per hour will be enough. "Why go faster, better safer, but at a lower cost." However, when some time passes after the purchase, the owner will want more speed in order to get to the destination faster.

After such a thought, the owners are thinking about how to tune their budget scooter and convert it into a high-speed two-wheeled "Monster". It's funny, but many people call this budget miracle that way. Of course, you can buy and install a Japanese-made tuning piston on a honda dio, but its cost is more than $ 200. And to install a piston of such a cost on a device that costs about $ 500 is, to put it mildly, not rational. It's easier to just buy a 100cc scooter initially and enjoy it without any tuning. Therefore, it is better to just do the tuning with your own hands and add speed to your scooter without throwing out huge costs for it.

Before you start disassembling the scooter and start improving the device, you need to figure out if your scooter is configured correctly. It is quite possible that if you clean the exhaust pipe, the air filter and tune the carburetor, then your Honda Dio will simply "Fly" on the roads.

Tuning for beginners

Initially, when the device was first purchased, you need to break it in, remove the speed limit and adjust the carburetor. If you do everything right and avoid mistakes (especially in setting up the carburetor), then as such, you won’t need it for the first time. It will become faster and respond quickly to the pressure of the gas handle.

If you like this initial setting of speed indicators and there is no longer a desire to increase the speed, then in principle this can be finished. With this setting, the maximum speed will reach up to 60 km per hour. The difference from the basic setting is not big, but the acceleration itself and gaining momentum will become much better. If you are satisfied with these indicators, then the tuning of the scooter can be completed.

More advanced tuning

If there are few such indicators and you want to minimum investment your honda dio was driving much faster and behaved much more briskly, then you need to take tuning more carefully and modernize many elements of the scooter itself.

Piston group tuning

The engineers who worked on the honda dio made it so that the dimensions of the crankcase would allow replacing the standard cylinder with a piston with a 39 mm and installing a unit with a 47 mm. If you perform such an operation and select a suitable piston with a cylinder (the same Athena is ideal), then the engine volume will increase as much as 74 cm3. It is worth noting that the replaced engine is most likely made of aluminum, which means that it is not necessary to be smart with different cooling systems. The engine, although larger, produces more power and increases speed, but does not require cooling.

Air filter tuning

The standard filter is made and installed not very well. The fact is that it gets dirty too often, which is why it needs to be constantly cleaned. In addition, it is installed in such a way that it is very difficult to get to it. He is also not able to pass enough air when installing a new piston. Therefore, it needs to be replaced.

You can install a regular car filter of a small size. But you need to install it in the trunk. The scooter has enough sealed luggage compartment, because of which the filter simply does not have enough air. Therefore, you need to make a small and not very noticeable air intake. But also do not forget that a lot of dust gets into it, so you should make a coarse filter for the air intake.

To connect the filter and the carburetor, you need to choose the right hose and just fasten it tightly. But not everything is so simple. Finding a suitable diameter is not difficult, but finding a hose that will not kink and create air obstructions is very difficult. One could choose a corrugated hose that does not kink when driving, but there is a strong swirl in it, which blocks the flow of air and thereby the entry of air into the carburetor itself. To improve the operation of the engine and filter, you need to find a hose from the cooling system with a VAZ - 2110. When the suspension vibrates, it does not bend and does not create any turbulence.

If everything is done correctly and installed good filter, then the scooter will pick up speed much faster, there will be enough air for the piston to work, and clean new filter it won't happen often. In addition, the noise from the filter is almost inaudible. The speed will increase by approximately 30-40%.

Silencer tuning

If you started tuning a Honda Dio and changed the piston performance, then you definitely need to change the muffler. The standard one is simply not able to cope with the air flow that is formed after upgrading or replacing the engine. In addition, the speed with such a silencer will not increase much. The scooter needs an exhaust pipe replacement! The most suitable model will be from Giannelli, but they have closed their production. But if you meet just such a model, then take it. It is worth noting that, having installed this exhaust pipe, you need to carefully consider the setting of the motor and not over-lean the mixture. But if such an exhaust pipe was not found for a scooter, then Tecnigas is quite suitable. This option is something worse and louder, but also pretty good.

Transmission tuning

Tuning a scooter will not do without reworking the transmission. The fact is that manufacturers did not take care of cooling too much about overheating of the gearbox, which can lead to rapid wear the transmission itself. You can make a simple cooling system that will direct the air flow to the transmission and to the gearbox itself. If you have good skills in engineering, then this is quite easy to do. Speed, of course, will play a key role in cooling efficiency, but this does not mean that you need to drive too fast, save your life.

Tuning is an opportunity to increase the power of motorcycles and give it an original appearance emphasizing the individuality of the owner. On our website you can pick up various spare parts for tuning mopeds and scooters:

Scooter tuning features

So, tuning this popular vehicle may need in several cases:

• you lack standard speed indicators that do not exceed 60 kilometers per hour;
• to increase the performance of the vehicle;
• to improve performance.

The whole process tuning muffler scooter model Honda Dio 18 and its other details consists of several successive stages. Each of them provides for certain operations with a particular part. Ideally, you should do something like this series of actions:

• replace the muffler with a tuning resonant pipe, pre-selected for the CPG;
• rebuild the transmission based on the characteristics of the tuning pipe;
• install a carburetor that has optimal diameter diffuser;
• replace a conventional variator with a sports one (which will increase the overall efficiency of the transmission part and the throttle response of the scooter);
• install a tuning CPG equipped with an extended volume of the Sport class;
• carry out the design of the engine on the tuning piston.

The above option can cost scooter owners a pretty penny, so let's consider the most a budget option which won't cost much.

Inexpensive tuning muffler and transmission Honda Dio 18

You can try to increase the maximum speed, performance and dynamics of the scooter using simple, "folk" methods and means.

So let's start muffler tuning Honda Dio 18. It will be necessary with the help of improvised materials clean from soot and dirt exhaust pipe and ducts. It is advisable to use sandpaper to remove flaws and excess casting. After such a simple operation, the motor will noticeably perk up.

The exhaust pipe can be cleaned in several steps: using blowtorch, or a cut along the seam and subsequent welding.

Next, we move on to the transmission. In most cases, the increase in maximum speed and the development of dynamics are hindered by its non-optimal setting. In CVTs, you can often find failed springs and half-worn weights. They definitely need to be replaced, so you need to purchase a set of springs and various weights in advance. First of all, we adjust the clutch, equipping it with stiffer springs.

Next step - setting up the variator. Here you should carefully select loads of a certain weight. The goal is to achieve the largest ratio width by using the belt to fully extend to a large radius. To do this, you need to remember a simple rule: the less the weight of the load, the more ratio and the higher the engine speed, the heavier - everything, respectively, is vice versa. It is important to choose loads with precisely the optimal weight, since excessively heavy ones can reduce dynamics, and light ones will reduce the possibility of developing a higher speed.

If the scooter is new, then you should immediately correctly adjust the carburetor, run it in, and then remove all speed limiters. Also, it is necessary to pay attention to the piston part: if the compression is below 8-10 atm., then it may be necessary to change the CPG rings. It is recommended to carefully polish the upper part of the piston, and clean the cylinder head.

And finally, revealing a little secret. In factories, most often, to limit the speed, they set a limit on the number of revolutions of the propulsion system. This is done using introduction of an additional wire v the electronic unit ignition control, which must be carefully removed.

As you can see, to achieve goals, you can use not only costly methods, but also very simple operations and little tricks. Just a few hours of work, and your "iron horse" will greatly cheer up and come to life. As a result - an increase in maximum speed, the development of dynamics and performance.
