Reply To: Dies on idle (after 1-3 minutes) – GV250
Go for a small ride and come back, let it cool down quickly , report back on how it ran on the road ? And then remove your plugs , check again.
NGK is a safe call for caps. And test the resistance of coils and report back the figures.
Check the manual and test your Lambda Sensor (O2 sensor) in the exhaust pipe too. These report back burnt (or unburnt) mixture back to the ECU. Sometimes they just crap out needing a replacement.
Although, the only way to be sure about any part is to use the manual and actually write down the figures reported , then you know if a cerrtain part needs replacing. It could take 1 random sensor or part to throw whole bike out of balance.
