Who's Stalled? (Stall of Fame)

Post by PeteH »

How about a thread similar to the Crash thread about engine stalls? With as many incidents of stalling as we've been hearing about, it would be nice to consolidate any symptoms and resolutions, in hopes that others can either prevent or recover from their own stalling situations.

So, if you would, please tell us the following:

1) What model Buddy? (year/model/approx. mileage)
2) Describe the stall or loss of power (speed, how long had you been rolling that day, your fuel level, etc.)
3) Were you able to restart? After how long?
4) Did the problem recur?
5) If resolved, what was the major cause, if known?
--> vacuum in the tank, bad fuel, particulates in the carb, bad stator, plug, ... ?

1) What model Buddy? (year/model/approx. mileage) 2009 Buddy 50, 7K+ miles.
2) Describe the stall or loss of power (speed, how long had you been rolling that day, your fuel level, etc.) No real pattern to it, except usually when caught in the rain.
3) Were you able to restart? After how long? Yes, after letting it sit for 5-15 minutes. Kickstart was a little more successful, probably because the battery was getting worn out from trying the starter.
4) Did the problem recur? Yes, during humid weather or when caught in the rain, once after riding through a big puddle.
5) If resolved, what was the major cause, if known? Old spark plug.

1) What model Buddy? (year/model/approx. mileage) 2009 Blackjack, 50 miles
2) Describe the stall or loss of power (speed, how long had you been rolling that day, your fuel level, etc.) Engine stalled all of a sudden after riding for 4 miles
3) Were you able to restart? After how long?
4) Did the problem recur? Yes, every time after restart it stalled again.
5) If resolved, what was the major cause, if known? Vaopr lock, loosening the gas cap and clean out the vapor system solved the problem once and for all. Currently hit the 10K mark and had never a problem again.

09 Itallia, 159 cc, 678 mile
2) Describe the stall or loss of power (speed, how long had you been rolling that day, your fuel level, etc.) Stalled when applying throttle.
3) Were you able to restart? After how long? Immediately, but it stalled again after a mile. After 2nd stall proceeded cautiously at 30 mph and later was able to get speed up to 40 mph. Afternoon - some cautious riding initially later was able to ride like before the problem started.
4) Did the problem recur? yes. Today again
5) If resolved, what was the major cause, if known? Don't know yet. Waiting to see mechanic. Meanwhile - Seafoam.

This weekend we are going for a long ride. I mean to rid of all of the gas in the tank and fill up fresh

(1) What model Buddy? (year/model/approx. mileage) Blackjack, 0-500 miles
2) Describe the stall or loss of power (speed, how long had you been rolling that day, your fuel level, etc.) very low speed, long and short rides and right after start up, low(er) on fuel
3) Were you able to restart? After how long? yes, immediately
(4) Did the problem recur? now and again, but never while out riding, exactly. just during "warm up" and at slow speeds. usually while driving in for gas, but the tank is not empty
(5)If resolved, what was the major cause, if known? idk? it hasn't had its first service yet, but will this or next week. so i attribute it to that, or the vapor lock issues

it runs fantastic when i ride it, really. no issues

1) What model Buddy? 2008 St. Tropez
2) Describe the stall or loss of power. I was riding along and then, all of a sudden nothing. It was awful.
3) Were you able to restart? After how long? Yes. After I pushed my scooter to a gas station and got some gas.
4) Did the problem recur? Yes. The next time I ran out of gas.
5) If resolved, what was the major cause, if known? I didn't stop for gas soon enough.

1) What model Buddy? 2008 International 150, ~5,000 at the time of the problem.
2) Describe the stall or loss of power (speed, how long had you been rolling that day, your fuel level, etc.) Going down the road at a good clip; 35 - 45 MPH, started losing power. The nature of the power loss was pulsing, like it was running out of gas.
3) Were you able to restart? After how long? Yes, it restarted pretty quickly but I had to crank more than usual.
4) Did the problem recur? Yes, each time I got low on gas.
5) If resolved, what was the major cause, if known? It was resolved. The issue was so called "vapor lock". I had allowed an overly helpful gas station attendant to fill my tank and he filled it to the top, causing the condition. I drilled holes in my gas cap and have not had an issue since.

If Sea Foam doesn't work, then no. The carb needs to be removed and the jets taken out.

It's fairly easy compared to something like valve work.

Today things went much better even in the morning. I started with venting the tank before I even started the engine. Then I started the engine and let it run for about 15 min. Tuned it off, vented the tank. Rode to work. It's like my old bike was back, It FLEW. I think in my case it was combination of some debris/bad gas, a bit more gas then usual a week ago, need to be warmed up more then usual for some reason and maybe the dreaded vapor lock - all played part. I am off course keeping close eye and I do not push the bike past 40 in the mornings. Just to be safe. I think 15-20 minute warm-up is the way to go for now.

2006 Blur (not Buddy), <500 miles

2) Describe the stall or loss of power (speed, how long had you been rolling that day, your fuel level, etc.)
I'd been riding all afternoon. Slowly but surely the bike had been running worse and worse, then it started stalling.

3) Were you able to restart? After how long?
It had stalled and restarted a few times. Finally it stalled and balked at restarting.

4) Did the problem recur?
Repeatedly.

5) If resolved, what was the major cause, if known?
--> vacuum in the tank, bad fuel, particulates in the carb, bad stator, plug, ... ?

It turned out that the air filter cover was loose and getting progressively worse as the day went on after being serviced. It was utterly simple to fix, but I had no idea. None. That's why I wanted this to be archived here in the Stall of Fame thread.

Excellent idea, PeteH!

I stalled my new Stella 4T once when I came to a stop at a light and simply forgot to pull in the clutch.

I've been switching back and forth between my automatic Vespas and the shifty Stella a lot, and simply forgot which one I was riding! :oops: :lol:

Stalling Buddy 150

Post by CROSSBOLT »

2009 Buddy 150 stalled and/or quit right out of the box, usually after riding for a few miles. Would always restart after a coupla minutes. Finally found the vent valve stuck shut and a Buddy dealer got me a new valve which came with new hoses and clamp. I plumbed the vent straight through while waiting for the valve assembly and the scoot NEVER stalled or quit but it would stink of raw gas after a ride. Put the new valve in yesterday and I think the problem is gonna reoccur since the idle speed goes up after riding a short distance. So I am gonna drill the cap since I cannot find a vented cap that small. I have over 1800 miles on the scoot and most of them are with the straight through vent. I will start with a #60 drill for the cap vent.

Here's my stalling entry.

I purchased the 2008 Buddy in Aug or Sept of that year. We never had any issues for the 2 or 3 months of riding time in the remainder of 08.

2009 was a different story. The scoot started having very intermittent stalling issues. While riding, it would lose power, wouldn't accelerate and would quickly stall out. It would always restart, sometimes immediately, sometimes after a minute or two. And that continued on throughout 2009, despite several trips back to the dealer. The dealer never identified a cause and didn't do much of anything to resolve the issue.

Because of MB, I was very aware of the infamous "vapor lock" issue, which is really a vacuum lock, so I ensured there was a vented gas cap, but that didn't solve the issue. Also because of MB, I became aware of a stator problem. I was strongly leaning toward that as the root cause of my problems. However, I could not convince the dealer and they wouldn't budge on replacing the stator. To my knowledge, the scoot had never been overfilled with gas ... I'm not 100% confident of that, because the better half sometimes did the gas fillup honors, but I did make her aware of the problems with the overfill.

Then came 2010. And the problem seemed to have mystically been resolved. Until late in the year, maybe Sept or Oct and it resurfaced and again was very intermittent. Of course not only was the scoot now out of warrenty, but the dealer had also gone out of business. Because of the very intermittent nature of the problems, the dealer had assured me they would log all problems and trips to the dealer and even if they eventually diagnosed the problem outside of the warrenty period, they would still honor it as a warrenty repair. Lesson learned there!

So, we'll see what 2011 has to bring. If the problem resurfaces, the scoot is likely going to get a little vacation time in the Scooterworks facilities.

Intermittent problems really suck!

Update for what it is worth: The #60 drill did the trick! that is a hole on the flat part next to the spring and one radially into the side. NO gas smell nor idle change nor fading nor stoppage.....

Now that is a sad sad story right there. Seems to be pretty common for these types of dealers to become "former dealers" and oh my, how convenient it is too.....

Good Luck!

2009 Blackjack. Picked this up used last fall and did not have a problem until the weather got into the upper 80's this past weekend. The first symptom was after a long ride after work, as I pull into the driveway the motor just cuts out. Thought maybe the idle was adjusted too slow. The next day, however, while running at about 60bmph the motor sputters, backfires, and stalls out. I'm able to get it started and get home but need to keep it below 35-40. Stalls out again at higher speeds. Do some research on MB and decide it probably the vapor/vacuum lock issue and both drill the cap and flip the valve that goes from the charcoal canister to the intake. So far so good now.

Update

Post by Stormswift »

I rode to work today. No problems. I am still doing routine warm up, then take off gas cap to vent the tank before riding. Don't know if this is helping or the problem is simply gone. I suspect it is gone. I think my scooter got "constipated" on either bad gas or it thinks it is BMW and needs the most expensive grade of gasoline. :evil: . IN either case it is getting the most expensive gas from now on (not that I was feeding it anything less then 89 before, mind you. And a dash of Seafoam, as usual

1) What model Buddy? (year/model/approx. mileage)
2008 Stella
2) Describe the stall or loss of power (speed, how long had you been rolling that day, your fuel level, etc.)
about 7 miles into the day's ride
3) Were you able to restart? After how long?
Yes as soon as I switched to reserve
4) Did the problem recur?
Not yet... but most likely after I use up this tank
5) If resolved, what was the major cause, if known?
Gas gauge does not work (its a stella thing)
I am planning on dropping it at Genuine in Chicago for a few things next weekend so hopefully that will get fixed as well

1) What model Buddy? (year/model/approx. mileage) 2009 Buddy, ~700 miles
2) Describe the stall or loss of power (speed, how long had you been rolling that day, your fuel level, etc.), stalls occur all over, after 5 minutes and after 20 minutes. Coming to a stop and accelerating. Speed of 10 to 40 mph. I haven't paid attention to gas level. Intermittent enough to cause issues in troubleshooting.
3) Were you able to restart? After how long? Restarts immediately, but may also stall again.
4) Did the problem recur? yes
5) If resolved, what was the major cause, if known? Not sure so far.

Possible vapor lock issue? The dealer has had it for 3 weeks, saying they cannot reproduce the issue. I'm taking it tomorrow and figure it out myself. It is very scary though to stall on a fast road.

Moron. I did it to myself.

I was out for a long ride yesterday, and was waiting until I'd crossed the bridge back into Missouri out of habit, as gas is substantially cheaper compared to the Illinois side. Old habit from driving the gas-guzzler. So I'm buzzing along, when all of a sudden I start to lose power. Visions of this thread run through my mind as the RPMs wind down, despite my frantic throttle-yanking. I'm running down the mental checklist - water in the tank, plugged carb jets, vacuum lock, stator failure, blocked fuel filter, kill switch, all of it, as I'm decelerating towards the shoulder of the road.

And then it hit me.

Yep, sure as hell, out of gas. My gauge had read about 1/8 as I crossed the bridge, so I knew I had to stop soon. But looking things over at the side of the road, I saw that I had gone 113 BDUs since filling up in the morning. Yep, that'll do it. So I was pretty sure it was _just_ the gas.

I wasn't going to push the Bud over two miles in 100-degree heat and humidity - I'd probably stroke out. So I call #1 son, give him directions, and tell him to bring the can of plain-old gas from under the deck. Fortunately, I had some drinking water with me. He shows up an hour later with the fuel/oil mix for the line trimmer, saying 'oh, this one seemed more full'. GRRRRR. We drove a mile or two down the road to the nearest station and got some fresh stuff, and Bud started right back up. Should I have called Roadside? Maybe. But I was pretty embarrassed.

Lesson #1: don't trust the gauge in the red.

Lesson #2: next time, actually take the MSR fuel bottle you just bought.

We live, we learn, we work on our tan. :D
