Hornet 600 not starting after stalling due to fuel

[TaeKwon125]

Hey guys,

I have a 1998 hornet 600.

I was riding it today and it cut out as it was out of fuel. I pulled over switched it reserve, no luck, wouldn't start. Found the prime the carb thing, tried that, no luck. With and without choke, no luck. Shook the fuel tank, no luck. Walked to the nearest petrol station, put 4.5 liters in, switched the fuel tap back to on. No luck. Repeated choke and prime and shaking, nothing.

What's next to try?

I suspect it would be air or dirt in the fuel line, but correct me if I am wrong.

Cheers, Olly

Forgive me for more insulting your intelligence but was the tank actually empty? You didn't just assume it had ran out of fuel, seems a bit strange it wouldn't start once filled up and turned over for a few seconds.. Unless there was masses of shit in the bottom of the tank.

Does it spin the starter motor and try?

Or nothing at all? /kill switch

Thanks for the reply, tank wasn't empty but had run out enough to need to switch to reserve around 85miles.

Kill switch is off, starter works, you can hear the engine turning, just won't start. Like when its too cold or no fuel going in. I'd guess its dirt in the tank too but not sure.

As a last resort, remove plugs drop some fuel in the barrel (only a little) and try then

Only 85 miles... was the tank not fully full to start with?

I've never made less than 100 miles, and that is riding really quite "uneconomically"

Never successfully managed to fumble and find the tap on the fly, always end up having to pull over and find it. Once it cuts out, it sometimes takes my bike 30-45 seconds of cranking to fire up again

if you switched to reserve there is a chance you dumped a load of water into the carbs.

If you really struggle, drain the float bowls and try again.

Fuel pump? It's inside the tank on the Hornet ja? Can you hear it?

Thanks for the replies guys.

Useful to know it doesn't have a fuel pump, so it can't be that that has gone.

I took the tank off this evening, emptied it (there really wasn't very much dirt in the fuel) and dismantled the tap that feeds the carbs.

There are three hoses connected to the fuel tank, one on the right seems to be a breather hose as it goes to nowhere (is not connected at one end). On the left there are two hoses, one which the fuel should come out of to the carbs and one that appears to be some sort of vacuum line connected to the engine.

Upon disconnecting the lines, no fuel came out. This tells me the fuel isn't getting past the tank into the hoses. The tap seemed to work when I played with it, so it makes me wonder if the vacuum hose has failed and the tap is not delivering fuel? If this is the case, there is a spring and diaphragm inside, is it a really bad idea to remove the spring from the diaphragm so that the tap will always be on even when the engine isn't running? The diahragm looks like this:

I have reassembled everything and recharged the battery so it I can try and get it started tomorrow. But I don't hold out much hope. What is my next option?

To answer another few questions, 85 miles isn't too surprising to be out of fuel as I had done a lot of short journeys with warming it up before hand, that coupled with a bit of "spirited" riding means 85 miles is enough to run out imho.

It did judder like it was missing at first, got off the roundabout I was on then it cut out.

As for water, I didn't see any in the fuel, and surely the line from the stopcock/ tap should be full of fuel so that is my problem?

Cheers

Have you tried sticking the tap back on and then sucking on the vacuum pipe to see if it opens up and fuel is flowing?

Cheers fore the help guys.

Sorted it in the end.

Petrol tank off, valve and stopcock out, cleaned and checked them. Poured some fuel into the line below, reassembled everything and jobs a good 'un.

Thanks again.
