Hi all,
Can anyone shed some light on this problem i have. well it gos like this, does not matter what time of day or weather, but when you first take off on your ride for the first time of the day you ride for about ten mins and the bike will just cut out, i stop the bike and lights are on dash etc, just as if you had turned the key ready to start again, so hit the button and away it gos and will now befine for has long a ride as you like. this will happen every time you first ride the bike, same each day, and cut out every time after ten mins, restart it and then all will be fine for the rest of the ride no matter for how long. if bike is left for a few hours the same thing will happen but if you have started and stopped it prior to the dreaded ten mins time limit all will be fine and will not cut out.
Sorry if this sounds a bit jumbled but its a strange jumbled problem. any one any ideas that could help me get to the bottom of this, many thanks for any help anyone may have.

Sounds kind of like the gas tank vent line could be pinched off, but this problem doesn't usually correct itself.

That would be the first thing I would check too. You might be able to rech under the tank and see if that hose is pimched off by the frame or the tank mounts. If it is, just pull the tank, put it back on making sure the hose is free.

That sounds like the vent hose is clogged by fuel/water condensate and once it's warm it lets enough air to pass to vent the tank (or if it's a late enough model a sticky tip-over valve in the same line). Try taking a section of line and attaching to to the vent nipple under the fuel cap and see if you can blow the line clear.

I think Ed probably has the right idea, If the problem persists might try taking the tip over valve out and either replace with a new one or a small piece of tubing. Good way to test this is to leave you gas cap loose next time you go and ride it for say 20 min and see what happens. If it doesn't cut out then you have a venting problem somewhere. Just keep an eye on the cap so you don't lose it.

Check your electrical connections. Battery cables (at both ends), fuses, backside of the fuse box, igniter, etc. Especially those under the tank. My theory is that, as things warm up and expand, you loose power to the ignition system. When the bike stops, heat rises from the engine and expands stuff even more and it makes contact again.
If it ere fuel flow, you would ride along fine, sputter to a stop and sit for a while whilst the system fills up again and then repeat all over.

greybeard has the right idea. check all electrics. Lots of issues with bike just dying without stuttering is usually electrical connections somewhere. battery and coil front wires are the first place to look. Then fusebox and all other connections, even the headlight connector can cause this to happen.

Hello Herb,
Sorry to hear about your problem. Could you clarify how the bike stalls. Does it quit when you are riding at speed or when you are stopped and idling? When it quits does it just stop or does it give you some warning (chugging, sputtering, etc)? My feeling regarding the problem is that it is probably fuel related given the fact that it quits at the same point in time (kind of like an engine coming off an improperly set up choke circuit, it either quits or sputters). How does the bike run after it stalls. Does it pull well in all throttle positions.
Best guess - try turning up your idle speed a bit. It is probably set too low as you come off the choke and is quitting.

That was my train of thought as well,if not enough gas was getting to the bowls but some was it would run until demand exceeded supply.
On the other hand though I have seen a bad coil work until it got hot and quit but work again once cooled off.

The boys are right it is a fuel venting problem. I had the same thing with my 05. I now have removed the roll-over valve and re-routed my vent tube. No troubles anymore.. It was quite a problem.. It took me a week to find it... Mine would do it at the weirdest times...Like making a left turn in traffic...Good luck..

ok we seem to be getting some were i think, re venting , on my last three rides i had the fuel cap loose as suggested and it did not cut out at all. im thinking the venting could be the problem, woohoo. so to try this out, my last two rides i screwed the tank cap closed again and thinking it would cut out has before but no it was ok. now im confused, but i think were on the right lines. gonna pull the tank this weekend and check the tube etc i will also check th electrical connections as well while at it. some one mentioned the coil could be the problem ?.
anyone any more thoughts on the venting or coil/ electrics to give me a bit of an idea ready for the weekend.
sorry to sound dumb but whats the tip over valve never heared of that. thanks every one

It's a small check valve intended to close vent line to prevent fuel spillage in case of a "tip over". Should be located in the vent line down near the carbs, sometimes they get a bit of crud in them and get stuck causing the vapor lock problem you've been having. That's where that extra lenght of tubing comes into play, you can put the tubing over the vent outlet under the filler cap and reset the valve by blowing into the tubing.

i have removed the tank and now will be looking into trying to find the cause of the problem. i have found the breather tube and traced it down to the tip over valve, a small black plastic thing in the middle of the tube, i hope thats it anyway. How can you test it is working ok and do you realy need it in there.
I have blown down the tube and you can feel air at the bottom, but when you suck on the tube it seems to start and then seems like the valve shuts off not allowing any air up the tube. does this seem right ? .
will also check out electric connections to while im at it any tips here also.
oh, pulled the plugs today as well and they seem a bit on the burnt looking side after 5000ks but still spark ok , (dont know if that will shed any light on the subject) re vent or elec problem
Thanks chaps

That's how it works all right. You blow to reset it if it gets stuck in the closed position.

Herb, also try connecting a small piece of hose to the small metal tube in the top of your tank, inside the fill area. This is the hose that feeds the breather system. Try blowing in there to see if it wide open. One member here was having breather issues and it turned out that the little metal hose thingy was tweaked and did not allow the tank to breathe. His tank had to be replaced (under warranty) to fix it finally.
Or...you can install one of the vented gas caps and be done with it.

My S/M does the same I stopped the problem by keeping the choke on about 1/2 until the motor was quite warm.
Hope it works for you.
