GOES DEAD

Does anybody REALLY know why this bike goes dead when you come to a stop??? It will run perfect for a month or two and then out of no where the going dead when coming to a stop starts. I took it in at 15K and had valves adjusted,new plugs,new air cleaner element,TB boots checked,you name it.I have tried every octane they make.More than half the time you can stop it by simply poping the gas tank lid open. But the vent tube is clear and run correctly.HELP!

We had a really warm summer this year in Scotland and my '02 V-Strom stalled a couple of times at yields/roundabouts. It happened enough for for me to notice, but not enough for it to be a frustration.

Spoke to the dealer and they said "welcome to high compression v-twins". We agreed we'd monitor but the weather changed and it's really not happened since, so it could be atmospheric. I can't remember if it's happened since the throttle bodies popped out of the inlet track a few months ago, so it could be an early indication (although this seems to be a rare event for any of us on this site...e.g. just me and someone in Texas).

Cheers.

goes dead

I recently bought an '02 with 12K miles and have had the same problem, but, like you mention, not every time I ride it. The bike has a PCIII and TB exhaust, although the first owner did not change the PC map fom the stock one. I think I'll try synching the throttle bodies, checking the throttle position sensor, and changing the PC map to the one meant for the TB exhaust and see what happens. I love the bike, but get a little concerned when it's acting up and I need to stop to make a left turn.

GOES DEAD

Thanks for the feedback guys! I guess I will just blame it on fuel for now. I have checked most everything else. It did it the worst when on a ride 89 octain was out and I went up instead of down to 87 percent. It ran really bad with premium....that was the only time it ever cut-out while riding along with the going dead when coming to a stop. So, I have run that fuel out and filled up with 87 and so far so good. I am going to run 87 only and see if the problem ceases.

Mine does it too. Have no clue why. It has even done it while rolling to a stop around 10 mph. If it was a single, I would understand.

Mine was doing this when I went to LA to ride with a friend, It spit/sputtered a couple of times and actually stalled coming to a stoplight once. That was before I hit 300 mile mark too.

I am lost on level of incompetence from a dealer. Since when it is normal engines just die off, regardless low or high compression, no. of cylinders, colour of the engine case, etc?

1. adjust idle to 1200 rpm
2. syncronize TBS
3. get the valves checked

If no.1-3 don't help, get the FI re-programmed slightly richer at low rpm. The basic problem: The engine refers to idle FI values with no load. These are adjusted lean for environmental reasons, and will lean even further in hot climate. This is also the backgound, if the engine runs rougher when it's hot weather.

Regards
Peter

just a general addition to Peter's good advise... adjust valves 1st, then sync TBS, then set idle rpm. i don't own a DL yet, but the order is the same for all engines and it does make a difference.

and, i have to respectfully interject a bit here. v-twins of all makes are more prone to sputters and stalls than their inline counter parts because the loping effect of the crank creates a good opportunity for kicking the pistons backwards (esp single pin cranks). this is the small price to pay for that sweet torque curve.

however, i would think that high compression/fuel injected/ECM v-twins could easily overcome this problem...? overall, good discussion.

I had the same problem when slowing to a stop - It quickly died.

Since I tightened up my throttled cables and made sure it was idling warm at 1200 rpm +/- The problem has gone away....

Cranks up ,great runs great, then after about 15 minutes of riding , it just stalls out at lower rpms in neutral, think i'll richen up the fuel at lower rpm's, maybe that will fix it
