Nov 8, 2022 at 6:40 AM in reply to: [Tutorial] Hyosung GV650 & GT650: Tip Over Sensor (TOS) Bypass Mod & C23 Fix #9031
I did not write this , but give credits to the lad who made this. (BTW, follow at your own risk!)
Quote from book :
The TOS sensor, the same in the GT650 and GV650, turns the ignition off when an emergency happens such as excessive tilting or the tipping over of the bike. If the sensor is not working it will create a situation whereby after a short time of about 2 seconds after the ignition is switched off the injection pump is disabled and you cannot fire up the engine. When this happens, the display will always show an “FI” error. When this happens the sensor should be checked. Put the bike into service mode. There should be displayed error c23. This means that the sensor is faulty and needs replacing. If there is any problem with buying a new sensor, or the price of about $ 100 is too high, you can hand-edit the faulty sensor for the engine to run properly not display FI error. The cost of modification is only the purchase of two resistors in the price of .30₵ – .40₵ cents. The only drawback of this modification is that if you tip over the bike while running, the ignition will not be stopped.

When that happens it will run normal then I’ll slow down to check code and red light go’s away so I can’t check the code. I also took the injectors out and cleaned them with carburetor cleaner and I used the battery and everything To get pull setting again it’s still kind of squirt but I don’t know if it’s dumping to much fuel or what

Welcome to the site, sorry that you’re having an issue with your fuel system. I assume you have found the service manual for the EFi 650 , in this forum. Then tricked your ECU to display error code on the dash. Did you get an error code or how did you come to this conclusion ? Does the same issue happen if you swap injectors between front & rear cylinders ?
