I’ve been having issues with my 2006 carby GT250 , my first ever bike, cutting power completely, as if the killswitch was tripped. to try and fix this I bypassed both the kickstand and clutch safety switches. after riding the bike for a good few hours, making sure to give a good ringing, this seemed to fix the issues, however as I went to start the bike up again it started cutting even more than before, ultimately stranding me 30 minutes from home with the only route home on a notoriously dangerous highway. If anyone has the slightest clue what it could be, help would be insanely appreciated.

Sounds like these should immediately resolve the issues for good (and it is common, even with other brands)
- Carbs = Take them off.
Verify they are Size 20 Pilots
Verify Main Jets are correct.
See tutorial below

- Replace or clean the fuel tap under the tank.
- Open the FUEL pump that is on the frame and use carb cleaner to clean gently
Next up, since the carb is apart , do the following
- Do the “Slide Mod” tutorial (recommended)
- Get the carbs involved in an ultrasonic cleaning process, it really really pays off.
Fuel = Try to use E5 grade fuel. if you have fuel that is E10 grade, you will have problems because there is nothing positive about using E10 grade fuel that some pumps wan’t to introduce , your country may have it under a different name but we call it E5 and E10 here in UK.
- Carbs = Take them off.
