GSXR Ignition Switch Bypass – A Step-by-Step Guide

The Suzuki GSX-R is a beloved sport bike, renowned for its speed and agility. Sadly, some owners may experience difficulty with the ignition switch – whether it won’t turn on or fails to start their engine properly. Therefore creating the need for a GSXR Ignition Switch Bypass. Fortunately, though, there is an easy fix: bypassing the ignition switch. In this article, we will explain exactly how to do just that; allowing you to get your GSX-R up and running in no time!

Before you start the process, make sure to gather a few supplies. Here’s what you’ll need:

  • 100 Ohm Resistor, 1/2 watt, 5% tolerance: Radio Shack part 271-1108
  • 18-20 Gauge Wire (two different colors)
  • Electrical Tape

Soldering was my tool of choice to make the connections, but if you’d rather use connectors and a crimping device, then it is essential that those supplies are easily accessible. I’m unsure how someone would effectively install the resistor without using a soldering iron.

Step By Step – GSXR Ignition Switch Bypass

Step 1 – Removing the Wiring Harness

To begin the process, detach both of the harnesses that require modification: a key switch and the right clip-on switch cluster. Unplug their connectors from the main wiring harness. The former has two links along the right frame spar while you’ll find one connector for latter just before your radiator on its correct side. To liberate these wiring systems, open some zip ties and loosen a clamp or two to get them free!

To get rid of the key switch, you need to take off the top triple clamp and unscrew both tamper resistant Torx bolts. Since I didn’t have appropriate Torx bits, I had to drill away the heads of these bolts. In order to detach the right clip-on switch cluster, remember that you must disconnect its throttle cables from the cluster first.

Step 2 – Modify the Key Switch Harness

To begin this endeavor, cut all of the wires two inches from their primary connector. When it comes to Br and Gr, make sure those cuts are slightly recessed since they will not be utilized in the future. Cut O/Y and B/W wires down one inch long then solder a lead from a 100 Ohm resistor onto each wire respectively. Once attached, secure with electrical tape for insulation purposes – making certain that neither wire nor resistor leads come into contact. Leave R and O at two inches for now; you’ll use these later on!

Step 3 – Modify the Right Clip-on Switch Cluster Harness

Our target is to reconfigure this harness in a manner that the circuit connected by the kill switch remains constantly active, and two wires coming from it link up with the same.

When the kill switch is flipped to “run,” an electrical circuit is established between O/B and O/W wires. The O/W wire connects directly with the starter button, forming a “Y” configuration about four inches down from the switch for maximum efficiency.

To begin, carefully cut into the sheath to locate where the O/W wire forms a “Y”. Then, trim away any excess of this same wire that leads up to its connection with the kill switch. Following that step, you will need to slice through and snip both ends of your O/B wires inside the harness and then solder them onto your newly disconnected section of O/W running over towards the Starter Switch area.

To conclude this process, thread two additional flexible wires throughout along within this same sheath before finally connecting these at their conclusion points on either side of your existing pair (O/W & O/B) from earlier – leading back up those originating connections coming off directly from said Kill Switch source.

To ensure a strong connection and to protect against any potential electrical issue, you must leave roughly three inches of wire exposed from the sheath at its connector end. To prevent electric shock or interference, wrap all the connections in electrical tape and also cover up where you’ve cut into the sheath.

Step 4 – Putting It Back Together

Connect the key switch and right clip-on switch cluster harness connectors to the main wiring harness. Examine R and O wires from the key switch harness, as well as two unconnected wires from the right clip-on switch cluster harness. If necessary, trim excess wire length for a neat connection when finished.

To finish your task, unplug the key switch harness and right clip-on switch cluster connectors. Then take the R wire from the key switch harness and join it with one of the unconnected wires in the right clip-on switch cluster connector. Next, attach another wire to this connection – more specifically, connect an O wire from the same key switch harness to that other unconnected part ofthe right clip-on setup. Finally, once all connections are made secure them by wrapping electrical tape around each area for insulation

To get your bike up and running, first set the kill switch to “stop” then plug in all necessary connectors. After that, move the kill switch to the “run” position and try starting your bike – if you’re successful, you’ll only be moments away from being ready for a spin!

Step 5 – Final Step

Securely reattach the appropriate clip-on switch cluster and neatly organize all wiring harness connections.

Our Final Thoughts on the GSXR Ignition Switch Bypass

Accessing the Suzuki GSXR Ignition Switch Bypass is a straightforward process that requires merely following this article’s instructions to get your bike running again.

However, this is only a short-term fix. If you encounter any problems with your bike, don’t hesitate to speak to an expert mechanic or the dealership to help properly fix your bike and remove the GSXR Ignition Switch Bypass. Keep in mind that bypassing the ignition switch can potentially void the warranty of your motorcycle and lead to further issues down the line.

Also note, that this method is readily available online and utilized by thieves so make sure you’re careful who you share this knowledge with.
