Increasing Performance (simple trick)
With a help of online gear sprocket combination calculator like gearing commander, simply input your desire sprocket and it will automatically generate all data from rpm againts speed, custom setup versus the oem set, you can even know the right rpm of your motorcycle in relation to speed, etc. etc. etc.
With changing your final drive reduction ratio you can give the impression that you motorcycle has more horsepower.
NOTE: The trick is not all combination will give power to your motorcycle, we are just re assigning to where we want the power to come in a desired RPM ramge of the bike, we cannot simply of course have both, the acceleration and top end, we change sprocket combination, for drive ability on street and highways. We can have acceleration but poor top end, or top end but lost acceleration, nonetheless, trying is everything. it is cheap, and yet easy to replace if you do not want the set-up and revert to stock combination.

Reusable Oil Filter
Been thinking of a way to minimize cost of my change oil change filter routine, that due to prices increasing on parts needed to maintain our engine..i have developed such filter that is useable and the only thing needed is the oil, that the filter may be used overtime, and not needed to replace it every routine..So why not make a reuseable Oil Filter out from stainless wire mess.
4-stroke Engine Condition Through Exhaust Smoke
1. Colourless or slightly blue smoke from exhaust
This means that your bike is very good condition. What you can assume is your fuel/air mixture is at the right composition and everything is well burnt in
your combustion chamber.

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)
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.

3 Phase Voltage regulator (SERIES TYPE)
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.

Understanding Motorcycle Switches
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
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.

KOSO speedometer panel
Koso speedometer panel for motorcycle are so cool when fitted to the bike, in replacement for those analog type. With its digital display and colorful backlight. A head turner indeed. But when it broke down..i mean get defective, it is like a disposable item.
Shown is a Koso speedometer panel for yamaha mio. A friend send it to me by parcel in request for me to look at it if there is a way to fixed the panel.
Unfortunately, at the end of this page, you will see why i said its kind of a disposable panel, but if there is a way to find the right program, yes a program, a firmware for its MCU perhaps, there is a slight chance it can be revived and repaired.

5 LED Motorcycle Headlight (review)
Led headlight for motorcycle are in the beginning of their trial and error process that many claim a thumbs up, these are those users who actually fitted it on their motorbike to name a few are yamaha mio, kawasaki fury, honda wave, and select unit with enough headroom on their headlight assembly. Variants come out in the open on three onboard high power leds, and as shown on the photo is a five led type with 5mm leds circled at the edge as to form a circle of light when main device is at the OFF position.
This article is just a review of the said led headlight for motorcycle and even for cars too but not as headlights but as an auxillary lighting.

Wireless helmet brake light (doorbell hack)
Photo shown is the donor gadget, transmitter on the left and receiver on the right side. The supply voltage of the transmitter is 12 volts, and can be directly tap on the motorcycle stoplight supply path, that when the brake is press, will enable it to transmit signal towards its receiver.If we analyze their circuit, the transmitter push button switch just enable and disable the supply, and when used on the brake light, the switch will be omitted, so no other modification is needed for it to work on this hack.
For the Receiver, the sound emitted by the module of course is not needed, and the sound chip must be disregard, and in its place, a switching transistor and a pair of 3 RED LED array is to be used. The receiver voltage supply is actually 3 volts only, Three led in series cannot be powered by that voltage so led forward voltage must be selected. In this hack, i'll be replacing the 3 volts up to 3.7 volts such as cellphone battery so that no other additional circuit that will waste battery power.

Spark Plug Cap Resistor
I recently encountered another problem with my suzuki ignition, that even if i am kicking the hell on the kick starter wont even nudge or start my bike. Ever since i added this ignition-wire-ground-strap , it became a tester of some sort due to the spark jumping on that shield ground, that from there it is telling me, the PLUG CAP resistor is too corroded to accept even an arc to feed the spark plug GAP. It has been three times i replaced my plug cap. so in the end, instead of buying the same crap, i made a minor modification using that plug cap and a resistor of 2.2k used in every electronic circuits.

Max16820att high power led string driver
In this page, tried using max16820at+t by maxim
The MAX16819/MAX16820, step-down constant-current high-brightness LED (HB LED) drivers provide a cost-effective solution for automotive interior/exterior lighting, architectural and ambient lighting, LED bulbs such as MR16 and other LED illumination applications.
The MAX16819/MAX16820 operate from a 4.5V to 28V input voltage range and feature a 5V/10mA on-board regulator. A high-side current-sense resistor adjusts the output current and a dedicated PWM input (DIM) enables a wide range of pulsed dimming.

7 segment gear indicator
The photo shown with separate gear indicator is very common nowadays with cheap bikes, A designated number on the panel tell us the gear position, (think outside the box here)....
Why not put a seven segment display to show the current gear position.
CIRCUIT
I derived the circuit from this seven segment gear indicator. I had built the unit, but not yet incorporate it inside my panel, it is under on my project plan.
This is the circuit i'll be using on this modification and eliminate the old indicator on my panel, consisting of very cheap and few parts readily available at any electronic part store, The heart of the circuit is based on the mighty 4511 , is a BCD to 7-Segment latch/decoder/driver, that will drive the seven segment display.
