Hi,

I have a Suzuki GS 150R, the bike they have marketed in India. The bike is brand new and runs smoothly. But sometimes very unpredictably dies out while running.

I checked the fuel tank and lines and found that there is no fuel supply problem.

Last night I went for a ride for about 10kms and parked it. Then after an hour or so I restarted it and went for just 300m when the engine died and refused to start.

It has not happened before the mechanics at the company so they think everything is fine (they can't see any symptoms of the problem).

Please advise,

Thank You

Likely fuel or spark, How did you see in the lines for blockage?
Did you remove the float bowl drain plug for fuel flow?
Many bikes have a vacuum line that allows fuel to flow whan cranking or running. When engine is off, fuel stops.
You can draw a vacuum with bike sitting, and Off to check flow. This is at your Petcock.

If your bike has a crank shaft or cam shaft sensor it could be going out. That happened on my Harley, got hot during a long parade and quit. Let it sit for maybe 30 minutes and it cranked back up.

Thanks for the suggestion outrigger. The problem was solved by one of my friends who saw that the air pipes to the fuel tank were bent, hence blocked. The problem has not recurred since fixing them. Thank you.

Thanks for the reply Stratmando. It is surprising how minor problems can prevent machines from running! The problem was solved by one of my friends who saw that the air pipes to the fuel tank were bent, hence blocked. The problem has not recurred since fixing them. Thank you.

I've seen that happen with Vehicles and Bikes when the vent is blocked. It creates a vacuum, removing gas cap and hearing the air rush in is a sign of the vent blocked.
Strange things happen.
Almost sounded Thermal related.
In Electronics we use a can of freeze or a heat gun to reveal Thermal Intermittants. Good you got it.

Glad to hear it. Ride Long Ride Safe
