About: I love making something about electronics, making something awesome and cool that I've never make before!

Hi Superbike or motorcycle lovers!

On this instructable, I'll share how to make your own Quick Shifter for cheap!

For people who lazy to read this instructable, just watch my video!

Note : For some bikes that already using Fuel Injection System, sometimes Check Engine indicator light up. just turn off the ignition key and turn it on again. but it's so infrequently so it will be okay

Enough intro just go to the steps!

Step 1: 1. What You Will Need? How About the Schematic?

READ THE SCHEMATIC FIRST, MAKE SURE YOU ARE NOT FOLLOWING WRONG SCHEMATIC.
OLD SCHEMATIC AT THE END OF PHOTO COLLECTION ON THIS STEP

So here is the parts that you will need :

  • Schematic
  • Arduino Nano, or anything smaller
  • ON OFF Switch (for bypass switch)
  • 16x2 I2C LCD Display
  • 2N2222 Transistor or any NPN Transistor
  • 12V Relay rated 10A at 24VDC or more
  • PCB (small is enough)
  • Small Multipurpose Box
  • 2 Small Switch Push Buttons
  • 1N4007 Diode or any kind of
  • Rear Brake Switch with the spring,
  • Steel Bar for making the spring holder
  • Pin Headers

for the brake switch, I'm using switch for Honda Grand because it's cheap

and don't use MOSFET instead of Relay. If you want to use Solid State one, use IGBT instead.

Step 2: 2. Code? Here Is..

I've made some revisions on this code, just check up my Github Gists page!

If you don't wanna use any display, You can use this Code.
If you want to use LCD Display, please use this Code.

Sorry for giving the code on other website :(
Asking for the libraries? Links are inside the code.

if you got an error when setting the timing, just make a EEPROM write code with value 70 on block 256 and 257

Step 3: 3. Solder All Components Into the Board!

for the LCD and push button, I make it separately.

LCD and buttons used for remote control for setting the timing of the module so you can use the LCD for other projects!

you just need to set the timing once.

on this pict, you might notice it that I'm using MOSFET. but please don't use MOSFET

Step 4: 4. Sensor/Switch Mounting

(Update) First things! You need to lubricate the brake switch, so it won't stuck if it's get wet and dry many times and keeps it smooth. Any lubricating liquid will work fine.

For the spring holder, I used the steel bar and you can place the spring holder anywhere do you want, or just mount it on the bolt that near on the footrest.

but I'll mount it and use the spring holder under the footrest

and route the spring behind the pedal rod linkage. (am I right?)

anyway, for the placement of the switch, i mount it on the shift linkage rod and I fix it with Zip Ties after I set the sensitivity

ah, you need an LED (12v or whatsoever) to know where the sensitivity is, just connect the LED to the switch and begin setting the sensitivity.

you might need to reset the sensitivity when you test it on the road. don't too sensitive or it might ruin your day (but for what I made the bypass switch?)

when routing the cable, give it a small excess of the cable or whatever it called. don't tighten the cable or you won't be able to downshift

Step 5: 5. Connect Everything!

First thing is place the module under the seat and remove bolts from the tank, route the cables from the relay on the module under the tank, make sure isn't pinched by the tank and keep away from it. then find the ignition coil.

after you found the coil, unplug 1 cable from the coil, then connect 1 cable from the relay on the module to the coil. and connect other cable from coil that has been unplugged from the coil to the other cable from the relay on the module

Route positive (VCC) and clutch cables from the module under bike frame, make sure isn't pinched by seat.

For the positive input (VCC) I connect it to the blinker relay, because it goes directly to the ignition key and every motorcycle is different wiring so you should search the nearly power source from the ignition key

and clutch cable (from the module) I connect it to the Clutch Relay

Negative cable? just connect it directly to the battery or the bolt on the bike frame (Ground)

don't forget to connect the switch relay! or it might not work

Step 6: Test It!

    Hi, how are you? very good project
    I have a doubt. When in the carburetor scheme, does it say "sensor" of which sensor does it speak?
    (by pass switch I think it is the change sensor) right? thank you!

    Question 27 days ago

    for a 4-cylinder motorcycle also should be hooked up in the coils? do you have enough in one or all or maybe in injection cables? what relay to use and how to solder it?

    if your bike using FI system, you need to connect it to the coils. If there is 4 coils, you can use 2 DPDT Relays with 2 transistors (don't forget to add diode. *read schematic). how to connect? unplug 1 cable from the coil (for the example coil no.1), then connect it to the COM1 pin on the DPDT Relay. Connect NC1 pin into the terminal on the coil1 that last time connected directly to the cable on your bike. do the same steps to all of your coils. if you use DPDT, on the coil2, connect it to the COM2 and NC2 (DPDT Relay has 2 pole 2 throw). or you can use 4 SPDT Relay (like on the schematic.) with more transistors and diodes. 4 relays, 4 transistors, 4 diodes (to protect the transistors from voltage collapse from the relay)

    did you mean Engine with 2 Cylinders? If so, you can use DPDT Relay or use 2 SPDT Relays with 2 Transistors and 2 Diodes

    what if i connect the relay to the kill switch?

    You can do that, but you need to make sure where the cable goes.

    hi..may i know..do you still need to use the Voltage Regulator LM7805 from 12v battery to power up the arduino board? in the previous version of the schametic i can see it.. but not in this new version..please advice

    That's used for preventing your motorcycle turned off when using clutch, so the Quick Shifter will be disabled when Clutch was pulled.

    "don't use MOSFET instead of Relay.
    why not use mosfet or transistor? they are faster

    Answer 4 months ago

    I've already tested using Mosfet, it can't handle the current and blown. No idea why, but I already put diode on it.

    I will making circuit update for this project, and might take some time because need to remake the video for it.

    Question 4 months ago on Step 2

    Hi. Many thanks for this awesome project!
    Perhaps you can help me with a little Problem with the Arduino compiler...I have problems to compile the code...It seems that I haven't the correct LiquidCrystal_I2C.h library?
    It's my first Arduino project.
    Can you help me?
    Best regards

    Sorry for that, but I forgot where I got the library from :(
    Maybe, I download it from github page.
    But I still have the library.. I can reupload it for you if you want
    Remember the library is for I2C

    Hi.

    I have tested the quickshifter on my aprilia rs125 on racetrack. very smooth switching the gears! perfekt! thanks a lot for that diy!

    But I did not use the brake light switch. It is too incosistant for me. I use a real quickshifter sensor.

    thx.

    best regards
