Led Tail/Brake Light Evolve



Filament bulb tail brake light bulb often failed due to the vibration at the back of any motorcycle, and it is un noticeable by the rider up until they are warned that they do not have a brake light to alert motorist at the back that you are stopping. I was once caught with a busted rear end light, thus this keeps me think of "Why not replace it with LED bulbs instead of filament bulb". In this way, i can conserve battery power, more reactive light at the rear when stopping, Yes led reacts faster than filament bulbs.

Horn Interrupter (flasher)

Motorcycle horn is basically the least seen to be modified with regards to the sound, one momentarily press of the horn switch, one sound, while as long press emits a continuous annoying sound. Why not make it lively  by just putting an interrupter (Flasher) to alternately on/off the horn to produce a machine gun like sound when the switch is press. Using a 555 timer ic that will be configured as an astable multivibrator, and a relay that can handle 10-15 amps, will do this trick. Moreover you do not even have to cut any existing wire for this to work and can revert the HORN system back to normal, in case it is not allowed in your area by the traffic law enforcers.

OVERVIEW 

Horn works very simple, the negative supply is the path that is being used on the HORN switch rather than the positive line. Why? perhaps to lessen and avoid voltage spike that may affect the ignition when the horn is activated drawing large current just to move its diaphragm to create the sound, such as the CDI and ECU of fuel injected machines, i may be wrong here,still that was my findings about the horn wiring on a motorcycle.

Photo shown is the basic motorcycle horn wiring without automotive relay. Basically an additional relay is fitted by others just to preserve the switch contact from wear since the configuration shown, the switch will always spark corroding its contact.

In this kind of setup, one momentary press of the horn switch, one sound emitted by the horns, one long press, one long annoying sound.

Here is a hint, instead of one press one sound, why not try the one press two successive sound, and one long press, will produce, a flashing or strobing sound. Any IDEA? we'll i have and you came to the right place, and the set-up will be very simple. no need to rewire, and no means of cutting your existing wire, so that in this kind of setup, once you did not appreciate the sound then unplugged the module and plug the horn, you'll basically be back to the original set-up.

LED Signal Light Bar End (how to make)

Having a handle bar end lights is pretty cool as well as added visibility during night time riding, There are lots of aftermarket part like this and sold almost everywhere at a very reasonable price. There is only one drawback on them, all are battery operated and somehow cannot be modified to work as an additional signal lights. So why not make a customized unit that can be directly tap on your motorcycle voltage supply as well as to your signal lights path to make them flash and just lit steady when signal is deactivated.

Many article posted here actually have photos and videos showing my bar end at work, and many of you are thinking how to make one, well sorry for the late responses. This article and post will show at least an idea on how to produce your own glowing bar end lights.

3 Phase Voltage regulator (SERIES TYPE)

CIRCUIT DESCRIPTION

The circuit is straight forward, It is not a shunt regulator, but a SERIES type of voltage regulator. D1 to D6 comprises the RECTIFIER diode which converts the AC generated by the 3 phase stator, Q1, Q2 and Q3 as the switch that controls the flow of voltage and current to charge the battery, Q1 and Q2 must be heatsink, since this type of regulator is in series mode, and no shunting will happen on all the windings, thus LOAD is particulary important on this kind of regulator.
IC2 inverting input has a two resistor in a differential way thus R4 and R5 is very critical on this design so the value must be at least 2% tolerance. When the IC2 input sense a high voltage, it switches ON Q4 and immediately allow it to control those power transistor flow via Q3, the circuit in RED is like a faucet that controls the flow of water. The circuit in GREEN are the voltage sense circuitry, and The Blue box is the source voltages with the rectifying diodes.

Suzuki Raider Shim Table

We all know Suzuki Raider both 125cc and the 150cc version do not have adjusting nut to adjust the valve clearance, but instead a SHIM is inserted and used to vary the clearance between the valve and the cams. Shown in the photo is the table of the shim selection for the raider, satria series of suzuki.

Upper table show the intake side

Understanding Motorcycle Switches

Ignition  performance (trick)

Understanding Switches of your motorcycle

We all know the characteristic of every switch out there that turns on and turns off the supply of any electronic equipment. They operate in such a way that the two contacts just slide with each other, and therefore prone to corrosion, moisture and degration. This in turns lower the efficiency since the contact is not 100 percent in contact with one another. More often, if the switch handle current more than their rated characteristics, then it heats up building more corrosion and blackening, producing more contact problems. A slight increase on their resistance, produces problems to current flow.

Now let us examine all possible switches there is on a motorcycle. What are they and what they are switching?

let us start, (add more on comments if i missed something)

IGNITION SWITCH
HORN switch
TURN SIGNAL switch
BREAK LIGHT switch (front and rear)
HEADLIGHT switch
HEADLIGHT BEAM switch (HI and LOW)

Now we will analyze each and one of them, i'll start from the bottom.

Shogun DC-CDI schematic

The picture shows an OEM dc-cdi of a Suzuki shogun 125cc that prior on my recent posting about kawasaki OEM dc-cdi, they are almost identical, parts used are almost exactly the same although in a different layout and or placement on the PCB. However, i recently found out the two dc-cdi differs on the design of their HV generator.


Digital DC-CDI by the way uses microprocessor on the pulse shaping circuit to maintain integrity and reliability of giving out right timing all the time when the spark plug will fire the combustible material inside the combustion, it is also to where the ignition map of the engine is stored for accurate timing. Many OEM uses MCU specific for their design and no available datasheet for us to understand it fully. This OEM upon analyzing the entire board has an Rx, Tx, and ground port, and if only i have the datasheet of the IC, perhaps we can be able to extract the data and dump it to a computer for further enhancement.

Raider R150 Wiring Diagram


Making modification on raider R150 electrical is difficult without the right electrical diagram. All bikes have a color coded wire for easy tracing when doing electrical works. Prior on my post with the FL125 (shogun electrical wiring diagram), in by request, wanting to have the diagram of raider r150.

FL125 wiring (Suzuki Shogun)

Troubleshooting wiring of any scooter or under bone type of motorcycles is easier if we have a handy schematic of the bike. When adding accessories, we need to determine what color of the wire is the right path of tapping anything to avoid electrical problems, such as blown fuse, wire heating up, etc.

Shown is the full wiring diagram of FL125 brand motorcycle by suzuki.
