| Electric Scooter Parts – Replacing a CDI Module |
8 Jan |
Powered by Max Banner Ads
One of the most common of electric scooter parts in need of replacement, the CDI module is as essential to the scooter ignition system as the spark plug. Thought to be an invention of the brilliant Nikola Tesla, the Capacitor Discharge Ignition (CDI) is the standard system used on most of today’s gas-powered motor scooters, as well as on many motorcycles, marine outboards and other small engines. A complete CDI module is made up of a transformer, the charging circuit, the rectifier, a capacitor, and the trigger circuit.
How the CDI Module Works
The transformer first raises the voltage to 400 to 600 volts. Moving along the charging circuit, the electric current charges the capacitor, with the rectifier preventing the capacitor from discharging before the ignition point. Receiving the triggering signal, the trigger circuit stops charging and allows the capacitor to discharge to the low inductance ignition coil. This increases the original 400-600 Volt capacitor discharge to as much as 40 kV at the secondary winding, jumping the spark plug gap, and igniting the gas/air mixture in the cylinder. The charging circuit is then reconnected and resumes charging the capacitor all over again.
AC or DC?
Most current scooters us an alternating current (AC) system; however the popular KYMCO scooter brand uses direct current (DC). As a result, electric scooter parts for KYMCO machines, including the CDI module, can sometimes be difficult to find.
Engine Size
It is always best to match the engine size to the CDI specifications. A CDI module made for a 50cc engine might work on a 100cc, 125cc, or 150cc engine, and some are designed to function over a range of engine sizes. Others however, will only work for a particular engine displacement. Always check the specifications to be sure of getting the correct scooter ignition parts.
2-stroke and 4-stroke Scooter Ignition
The 2-stroke and 4-stroke engines are completely different, and as a result, their engines’ ignition timing is totally different as well. You cannot use a CDI made for a 2-stroker on a 4-stroke scooter. Conversely, you cannot use a 4-stroke scooter’s CDI on a 2-stroke scooter.
Connectors
On many current CDIs, the connectors are integral to the unit’s case, forming a plug that snaps directly on to the scooter’s wiring harness. On other models, the connectors may be located on wires, allowing some leeway on exactly where the module is mounted. The skillful mechanic may shorten or lengthen these wires as necessary. The most common CDI connector style uses two plugs side by side; one 4-pin plug, and a 2-pin plug. These connectors may be square, rectangular, or simple spades.
Note: Photo illustrations of many CDI connectors can be seen at the website listed at the bottom of this article.
Unrestricted or Restricted?
An unrestricted (or racing) CDI provides the current no matter how high the engine RPMs go. As the CDI controls the spark plug, the plug will continue to fire at high RPM. For reasons that should be obvious, these CDI units are made for racing use, and are not very suitable for regular highway use. A restricted CDI module however, will stop firing once a pre-set engine RPM is attained. Without current reaching the spark plug, the engine RPMs slow to below the pre-set limit and only then will the CDI resume providing current to the plug.
When replacing a CDI module, or any other scooter ignition or electric scooter parts, it is always a good idea to reference your owner’s manual. If the manual is lost or otherwise missing, many manufacturers and brands have downloadable manuals available on their websites.

| Scooter Parts – Be Careful When Purchasing Them Used |
27 Feb |
Like most motorized vehicles, there will be instances when replacement parts are going to be needed. Scooter parts break down and malfunction just like anything else and care should be taken as to where you buy them. There are many places to obtain parts, but when it comes to safety, caution should be used as to where you purchase these parts. If you are not careful you could buy parts that should have been scrapped rather than resold and there are a lot of people that will sell you defective ones but tell you they’re new. It helps to know what you’re looking for especially when dealing with used dealers. It’s not that all used parts dealers on sneaky and underhanded, but caution should be used when dealing with them and sometimes the best way to do that is by researching or word of mouth in order to find a dealer that is reputable.
Buying new scooter parts is always a safe way to go as they have been shipped straight from the manufacturers. You know that the odds of getting a defective or damaged part are slim as opposed to buying them used and on the rare occasion that one is found to be damaged or defective, there is usually a warranty to have that part either fixed or replaced depending on the problem. There will also be times where you won’t be able to find a particular part at a used parts dealer and the only way to purchase that part would be to order it brand new and this situation occurs more times than one would think. Another consideration is of course, the cost of parts. When you’re are seeking to buy new replacement parts, you will no doubt find better prices and rebate deals to help save you money. The downside to buying new replacements is that on occasion a dealer will be out of stock on an item and will have to order it special. The wait for it to come in is indeterminate and in some cases, you could wait weeks for confirmation that it arrived.
As stated earlier, caution should be taken when dealing with used parts dealers and a good amount of research or looking around for a reputable dealer can save you a lot of time and aggravation. The benefit of buying used replacement parts is that in most cases, the parts are cheaper. One of the downsides however, is that unlike new scooter parts, one that is bought used is not likely to come with any warranty. So if you get it home and it turns out to be defective, you may not be able to get your money back but instead be able to trade it in for another part.
| Audi Key Parts – Brake Hose and Clutch |
6 Nov |
As a subsidiary of the Volkswagen Group since 1964, Audi has been widely recognized for its production of elite and luxury cars. The German-based automobile manufacturer has proven the company’s worth over and over again by producing cars that have, time and again, turned into commercially successful vehicles. Since Audi vehicles incorporate car parts made only from quality materials, Audi cars last longer, perform greater and look better than a great many cars in the market. One reason for this is how the company believes that each and every part able to enhance the performance of their car models should all be given equal attention. In this case, two such engine parts that must not be forgotten are the Audi Brake Hose and Audi Clutch.
The Audi Brake Hose is the part that connects the master cylinder to the car’s wheels together with the brake lines. The brake hose is made of specially constructed flexible tubes that come with metal ends. It is principally responsible for the transmission of fluid. Transmission occurs under conditions of great pressure. The whole of the hydraulic system is filled with a unique brake fluid which is pushed through the a number of Audi Brake Hoses by the movement of the pistons. Aside from this function, an Audi Brake Hose ensures that the high-pressure hydraulic fluid passes through the brake calipers. This is a sensitive process as the brake fluid must never leak out from the Audi Brake Hose. Another thing that the Audi Brake Hoses prevents from happening is the vaporization of the fluid which is why these hoses must be airtight at all times.
On another part of the engine, one will find the Audi Clutch. More often than not, manual transmission is preferred over automatic by drivers, especially racers, since it affords them better control of the car. This is pretty much the same scenario with Audi drivers. To ensure that drivers do get to enjoy absolute control over their rides, one of the most essential parts that a manual transmission system employs is the Audi clutch. This part engages and disengages the engine to the gearbox and directs torque to the vehicle’s transmission faster than the blink of the eyeâ??improving and maintaining system efficiency and performance. Either way one may look at it, both Audi parts afford With the functions these two Audi parts provide, drivers must take note to always keep them in proper condition.
| World Standard Audi 9000 Parts Make Audi a Byword |
24 Oct |
The Audi 9000 is considered by many as a landmark vehicle in car engineering. Its introduction in 1995 as a concept car made people take a second look at Audi models. With the car’s distinctive, bowfront aluminum body and undefined bumpers, the Audi 9000 started a shift toward the automotive design method called angular styling. It is believed that the sleek bodywork of the Audi 9000 captured the attention of the auto industry, and this interest has been sustained by the Audi 9000 parts specs fitted on the vehicle.
One of the greater lights of the Audi 9000 parts is its transversely mounted engine. This particular Audi 9000 part was first available with a 1.8 L turbocharged, inline, four-cylinder, 20-valve engine. For the first two years of production, both front-wheel drive and quattro models of the Audi 9000 parts featured a 132 kW version of the engine. In 2001, a more powerful quattro Audi 9000 parts model was released. Equipped with a 165 kW engine, the first-generation of the Audi 9000 has parts that share the same basic design of the original but features a larger turbocharger, an additional intercooler on the driver’s side, forged connecting rods, a dual exhaust, and a few other internals designed to accommodate the increase in turbo boost from roughly 10 psi peak to 15. Over the years, Audi has developed parts for the 9000 with considerable improvements, including a lightened and power-boosted Audi 9000 parts for its ?quattro-Sport” model. Capable of producing up to 176 kW and a top speed of 250 kph, the quattro-Sport is supported by Audi 9000 parts designed to exhibit understeer during drive conditions. Understeer is a characteristic determined by Audi 9000 suspension parts design, such as the effect of the all-wheel drive system.
Understeer is inherently a safer handling characteristic, as it is easier for novice and casual drivers to predict and control the vehicle. In addition, a number of modifications on Audi 9000 parts included the inclusion of Audi 9000 parts like the rear-wing spoilers and improved understeer suspension settings while the original four cylinder engine range was complemented with a 184 kW, 3.2-L VR6 in early 2003, which comes with the quattro all-wheel drive system. In October of 2004 a new dual-clutch gearbox and stiffer suspension were included in the Audi 9000 parts system.
