Quick (Cheap) Swifter
« on: December 06, 2017, 01:14:47 PM »
Hey guys... this is my first contribution here.. I would like to share an idea that I've implemented last week.. and so far is working fine!

I bought an old GS to learn about motorcycle mechanics, tweaks and to take her to the track in a near future...

So after understanding the Quick shifter principles. I bought a relay (4 poles - 12V) that has the normally opened and normally closed contacts.

So I connected the coils (orange wires) through the relay on the normally closed connection.. so the bike works as it should.

From passing light ( that I do not use) I disconnected the original wiring (only one) pulled a wire that feeds 12V when pressed to the relay... and that's it!

I used a 4 pole relay.. and using 2 contacts per coil.

Initially I was concerned about vibration... however it have not interference in the relay (similar to this one)



When pressing the PASS switch the ignition is cut.

At first, I did for the fun.. but it really worked nicely...(high revs especially)

Just put a bit of pressure on the gear lever up.. and a quick tap on the PASS button (even the lettering worked  :laugh:)
and the next gear engages.

Sometimes.. even pops... and so a smile on my face.... :icon_lol:

I can try to post a vid or photos

but is very straightway

thats pretty cool kito, dead creative  :thumb: i've played with the idea of making a switch on the gear lever linkage on another bike but i've never got round to it. i do love rapid clutchless upshifts when snapping the throttle shut but the ignition cut on a quickshifter would make for some hilarious backfiring action  :icon_twisted: :icon_lol:

current project list:
//cbr 600 f3 fighter
//gsxr 1100 mental oldskool supersport
//gs500 daily rat tracker cafe fighter that changes every couple of month... cafe fighter?

Indeed it is fun!... ohh yeah!
I swear that soon as I get a gopro like camera I post a video with some pops! Perhaps some exhaust takes can show what is happening on the pipe ...Who knows some fire flames are going out too  :D

I found easier to get pops when shifting near of 9k rpm... (which thankfully match with the engine useful range)
  I believe is that related with the pressure wave (like an acoustic standing wave) that is formed inside the piping that allows the explosion happen (more probable at least) in the exhaust.

What I like in this configuration is that all the stock configuration remains.. so if you don't  feel like Q-shifting .. you dont need to do nothing....
