► Unexpected stalling issue

[v8legend]

Hi,

So sadly the bikes back with the garage this week trying to resolve this ongoing problem. The only thing that seems to solve it sometimes is a magic 3 twists of the throttle and restart.

There was a way of calibrating the throttle on my old F650GS. From memory, you turn the ignition on, wind the throttle open fully in a steady and controlled manner, then wind it back the same way and turn off the ignition. I'm not sure if the 800 runs the same system (I've never had to try it!).

I hope that makes sense?

Maybe something has failed, and your bike is 'forgetting' its settings. It might be worth trying the calibration thing every time before you start your bike (I doubt it needs three twists). Then if the problem goes away, at least the dealer has something to work on. My guess is that this is something to do with the ecu.

There was a recall on the F650 twin for the air filter based on the production date. Mine was one of the ones that had collapsed and I do remember the stalling issue was quite pronounced and the difficulty in starting at some times, especially humid evenings.
It is a simple thing to check, don't expect BMW to do anything and don't assume they have checked it. When was the last time you changed it?
I've had my F650 2009 since September of 2009 and I have begun to cut in half the recommended service intervals for oil and filter and the air filter. You can call me paranoid, but 10,000kms between oil and filter changes on a bike just doesn't feel right to me.

Day 4

Thanks for your replies, 4th day in the garage and they are apparently only checking spark plugs and airbox now. I was told 3 twists reprograms the fuel mapping? I will ask about the slow opening of throttle to calibrate. At least the problem has shown itself once again to the garage. Bike was plugged into computer at the time and showed no issues. They are awaiting comment from HQ in Madrid. At least the weather here is not so great for the weekend, eases the pain of being without bike somewhat. cheers

Day 5

Checking cylinder compression today.
Am I alone in thinking the much slowed process of taking orders from BMW HQ before the surely experienced mechanics on site can do anything is a waste of time?
Is this a normal part of the BMW warranty experience that i'm not enjoying?
What demands can be made from me, other than please fix my bike BMW?
Sun is out and that just makes the pain greater.

Day 7 result? Throttle valve switch.

So the end of my idle speed problems? We shall see.
After 7 work days with BMW the part at fault is apparently a throttle valve switch with part nº 13547696412

After first swapping it out for a second hand part on Monday the bike has been starting fine for the last 48hrs and with a new part fitted today all seems well again.

Apparently not covered by the diagnostics device and therefore why it took so long to find.
The cynic in me says a mechanic might have found this quicker without bouncing questions between HQ’s and garage, but this I am told is the normal process to follow with a bike under warranty.
I am by no means a technical wiz but surely modern bikes like this cannot be so far advanced that a common sense approach to this problem could not have found this sooner?

So to anyone suffering a similar problem as my 2010 GS8 I hope this info may save you days without your bike and hours searching the Internet.
For specific symptoms with this case either drop me a PM or trawl the backlog of my continual moaning on this topic here.

Gonna be so happy to ride away from the garage tomorrow with a bike running 100%.
Does seven days separated from bike equal % discount from BMW when it comes round to service time? We'll see.

Just come back from a test ride on a 12 plate F650 GS, with a view to getting one for Denise when her restriction runs out. She followed me on her 250 and we had a nimble to the Ponderosa for a brew. At the first set of lights we came to, the bike stalled as I sat there with the clutch in. At the next set it stalled as I rolled to a halt, again with the clutch in. A few miles later as I roll into a roundabout in 3rd, as soon as I pull the clutch in the bike dies! All the way there I can stall the bike whenever I'm off the throttle.
While Denise got the coffees, I twiddled the throttle cable adjuster to try to get a little more tickover, which I managed but then had no free play. It was better on the way back, but then we dropped Denise's bike back at home and rode to the dealer two up. It stalled twice in the ten minutes it took to get there.
Fantastic little bike, but there's no way I would let Denise out on one until I was confident this issue was sorted.
The salesman uses this bike himself, and said it had never happened to him, but it had been in the workshop prior to me riding it. I'll be very interested to hear what they come up with, as I've suggested it needs looking at before they let anyone else out on it.
Unless it's just me?

BMW F650GS 2008 Twin Engine Cut

Hi all,
Got a call from the wife today, stuck at the side of the road after engine had cutout just after leaving a roundabout. She stayed calm clutched and parked safely on the hard shoulder so all good, thank goodness. The fuel gauge was showing about 3/4 full. Engine would turn over but not fire up. On opening the fuel tank cap there was a loud hiss of air so it was obvious a venting issue is the root cause.. Tank quantity now fell. Still would not start so it was also empty. We had brought fuel just in case and it fired up instantly when topped up.
She had been driving the bike in our wonderful Summer of rain over the last number of days. Is there a known problem with the venting system, and any warranty or other sugested fix for this issue. Any assistance much appreciated.

Best regards PJ

2012 F700 stalling

I'm new to this forum and BMW bikes but I thought I'd add to this thread.

I'm looking for a replacement bike and the F700 GS seemed to tick all the boxes so I booked a test ride. I rode the bike, a 2012 F700GS with around 3k miles on it. I was impressed by the bikes agility, power and smoothness, although I found the engine a little 'Bland'

Anyway, during a test lasting around an hour it stalled 4 times. The first couple of stalls were as I was rolling up to a red light, I assumed I was a bit slow pulling the clutch in, next stall was stopped in 1st holding the clutch in at idle waiting to pull out onto a roundabout, I say stall but I mean it just cut out at idle, last time was filtering thro traffic, again it stalled in 1st at idle holding the clutch in. By now I was now suspicious that it was the bike rather than me at fault. I returned it to the dealer, I didn't mention the stalling issue as I was running late . That evening I googled for 'F700 Stalling' and found this thread and many other related threads in many forums confirming my suspicions - OMG - thankyou Google!

Based on the fact that the stalling issue discussed in this thread and similar threads in other forums now span over 4 yrs production, clearly, without apparent resolution I certainly won't be buying.

Thanks to all the contributors.

Now moving on to test the 2012 V-Strom 650 and Tiger 800!

 

[MikeMike]

My stalling issues were pretty much eliminated when I had to fit a new fuel pump controller. Also, if you rev the bike the engine is by no means bland.
Above 7,000rpm changing gear from 3rd to 4th is quite addictive!
Book another test ride at another dealer and rev the bike this time.
The V-Strom has less power and the Triumphs run on the warm side.

Had a new fuel pump controller fitted when my bike would not start in November. In December, it stalled at a set of traffic lights with 1/8 tank. Filling up, it was OK. Last Friday, the bike stalled a couple of times, this time with 1/4 tank. In both cases, I was heading down hill. Bike currently at Ocean BMW...

This was a fairly common problem when the bike was released (2008). It happened to my mates bike, but not mine. It was sorted with a software upgrade. I can't believe they've reintroduced a problem?

It was entertaining that the bike was collected by the biggest truck in the fleet!

Hopefully the new 'fuel sensor' being fitted today will sort it out.

I've been underwhelmed by the lackluster communication from Ocean BMW .
- though was impressed with the 40% discount last weekend on a v3 twat suit...

 

[earthmover]

As an update on our experiences, despite the issue with the bike we had on test, enough people we spoke to rated the bike very highly. A 2008 plate with 20k on the clock came up and I bought it for Denise. We haven't had a single stalling issue with this bike.
Cheers

I experience 6 time stalling when coming to a stop or at slow speed.(speed 10-30km/hr) It had occurred with the clutch engaged (i.e clutch lever out/released) or disengaged (lever pulled in)

When In gear 2 & 3 . Occur once during a bend when slowing down fr gear 4 to 3 . I release the clutch at gear 3 and the engine stall n my rear end skid and I was lucky to counter back.it all video

I had no problem when starting up but on two occasion the idling go surging n stalled.

Send in to BMW Dealer to check things up. Was told they cant replicate the problem and they didnt upgrade the ECU software. Instate they change a new TPS (Throttle Position Sensor) @14000km mileage and so far so good till now.(@14250km mileage) with no stalling issues.

 

[Murpies]

Hi it me again. The stalling is back but it happen only when slowing at traffic in gear 2 clutch in. The engine just cut out. Immediately I push the starter n it start right up, after tat it went fine. It happen in 3 occasion now. So far no surging of the engine. It all happen after the 20k servicing and battery replace as it usage for abt 2yr . Will be going to dealer n see wat they can rectify it.

 

[Murpies]

Today it didn't stall but saw this on the OBC - (EWS) error code when I switch on and off the ignition. Could it be the culprit of the stalling issue?

2009 650
I had read about this problem but had assumed I was a "lucky one" - today it happened three times on the way home - hot weather (well 25c is hot for us!) only 36 miles range so low fuel. Will fill up and see if it runs ok.
looking at this thread as a possible solution

Thanks for the info. Today starting up the bike and have no issue engine running smoothly at (temp 25degreeC).

For the EWS error , I was on main stand and let the bike running fr gear 1-2 then try clutch in to stimulate the cut out. When the error appear while off & on the ignition.
Will monitor the situation.

 

[v8legend]

I can't be certain, but I think that showed on mine when the fan failed. Make sure your fan is working ok.
