Honda Vision 110 cutting out when cold

[barryd]

My Honda Vision has been stood for six months (only used for motorhome trips in the summer) and it was due a service. It started first time though and I gave it a run round. After a mile or so I noticed it was cutting out and kept stalling at low revs.

Had it all serviced, new belt, battery, fuel changed, fuel filter cleaned new plug etc. Went to pick it up and it was still cutting out. Took it back and the mechanic had a go on it and said it was fine. I then had a go and it was ok. Rode it home about 15 miles full chat and it was fine. Today went to start it and it started ok but even after leaving it ticking over for 5 min when I drove off on it it kept cutting out as soon as I applied revs. Trouble restarting it several times as well. Drove it up and down the village coaxing it along for 10 minutes or so and eventually it got going and seemed fine but something is wrong.

ITs not right though. Ive had it four years and normally you turn it over from cold, jump on it and away you go.

I think its fuel injection so would it have an automatic choke? Could it be that? Ive not called the bike garage yet but thought I would put this out there as I suspect ill get a lot of hmmms and scratching of heads.

I had one here yesterday
It has no choke as its FI
It just squirts a bit extra juice in when the sensors indicate it's
below optimum operating temp.

does it smell of petrol at all ?
If it isn't getting a reliable signal from a temp sensor
it may continue to give it plenty as it warms up causing similar symptoms to what your getting. ie flooding

Sounds like the symptoms of fuel vacuum lock.

Thanks for those helpful replies. No smell of petrol that I noticed. Garage has offered to come and pick it up on Monday and investigate. They are good lads I think at our bike garage (Darlington) but I guess I cant expect them to know every bike, model and problem so any pre investigation ideas are going to be helpful.

Its been such a reliable little bike. Its been all over Europe on the back of our camper van and never let me down. Must be something simple hopefully as it runs sweet once fully warmed up.

Condensation buildup in fuel tank perhaps?

My efi bike started stalling when coming to a stop for the first 5-10 minutes.

Came down to faulty throttle position sensor.

Not sure of your bike, just thought I'd share as it had me puzzled at first.

[barryd]

Thanks. If it was just condensation would it not happen all the time? They replaced the fuel I believe. Its not just stalling either its cutting out when you try and turn the throttle, it dies but generally keeps going, just. There are two hills going in either direction out of our village and until it was properly warmed up it would not get up either of them as it kept dying until I turned around. Once fully warmed up after about 10-15 minutes it was fine.

[Robby]

Well it sounds like something up with the fuelling when cold, and it's been sitting for a long time.
Lots of potential causes, but my first approach to fixing it would be to fill it up with fresh fuel and take it for a few rides. The combination of fresh petrol, heat and vibration will tend to clean up and free off anything which is a bit dirty or sticky.

[barryd]

[Robby]

Ok, so the fuel and filter are good, its just a case of using that new fuel to clean everything downstream of the filter when the weather is good enough to ride it.

I would just try to get in a couple of half-hour rides. If it is behaving a bit better after them, then it should keep improving. If it isn't, then it needs proper fixing.

I would be loathe to put it right back into a garage before a couple of rides, because the usual method employed to diagnose any kind of FI fuelling fault is to keep replacing expensive components until the problem goes away. The problem is often just a switch, sensor or solenoid sticking in one position, which will free off with heat and vibration.

spark plug caps are prone to being weak on these.
Replace for a new one if you haven't already.

As Robbie said fresh fuel and shell v power 97 works better and has been known to me to cure some running issues.

Had the bike out again today. Same problem. It fired up straight away but died then kept starting it and catching the revs. Took off up the road and immediately it started to die and then wouldnt start at all, just spinning over. Tried it with the fuel cap off in case it was a vacuum thing but didnt seem to make any difference.

Going back to what TM Forte (Jason King) mentioned earlier there was a strong smell of fuel at this point. I know your not supposed to but I then tried blipping the throttle a bit when it was turning over and it tried to catch but didnt. Left it ten minutes, did something else then tried it again. Started and I just caught the revs and kept it going with the back wheel spinning off the ground.

Couple of minutes of that then off up the road. Coughed and died a little bit but kept going, after a few minutes up and down the road it was fine again. So gave it a good blast round the villages but it will take an age to run off all that fuel its so economical.

Going out now so will try it again when I get back.

I reckon it has to go back but will see later and tomorrow if its still the same.

[WD Forte]

Is it really a cold start problem?
It sounds as if it starts ok but struggles to keep going.

All we can do on forums is make guesses and suggestions
based on info given and sometimes personal experience
so good info = better guesses and vice versa.

The guy who brings his scoots here just bought a new Motobatt battery for his 2018 vision and reckoned it made a lot of difference in starting and performance where previously it was an erratic PITA.
I havent tinkered with it as it's under warranty and Fowlers should be sorting it but he tells me they're useless and had it two weeks and did nothing useful

Its a bit better today. Started first time and went off up the road no bother. It was actually coming back down the hill (about half a mile from the house) that it started to splutter. Kept going and died when I stopped outside the house. Took the fuel cap off to see if there was some kind of vacuum or blockage but it seemed fine. Few turns to get it started and then zipped up and down the village ok.

Its a much warmer day today though so would it really make a difference? Maybe whatever it is is slowly clearing and just needs more riding as suggested. I would have gone further but I have a nuclear hangover.

It seems to be failing as it warms up. Could it be the coil failing?

Been all over on the bike today. Had to drop the camper off twenty miles away and went back for it just now on the bike.

Again earlier on today it was a bit iffy at first for a few rides round the village but not as bad as it has been. Cutting out at low revs and struggling to get going. Twenty mile blast flat out round country roads to pick up the van, no problems at all and no cutting out once warmed up.

Im wondering about trying some of that injector cleaner but which one? A lot of reviews seem to say its snake oil but worth a go I suppose.

[Sister Sledge]

Nobby's touching on something ^^
I've heard of coils failing slowly too. Could it be that? Do you have a spare to test the theory?

Coils usually break down when they get hot, then start working again once cold. So this is the opposite of normal coil failure.

I have never known injector cleaner to do anything at all. A tank of super unleaded usually contains some kind of cleaner stuff anyway, so go for that.

So it looks the scooter is still running a bit shit when cold, but fine after a bit of a run. I would want to find a way to check any fault codes stored on it now, seeing as the problem is still clearly there, if less of a problem than it was. Something on the warm-up map in the ECU isn't getting the right input from a sensor, and it sounds like it's not running rich enough to stay happy. Similar to running a carbed bike cold without using the choke.

Just thought I would update the thread again. Over the summer the bike was fine after daily use. However it was warmer weather. It's been stood for three weeks and I've started using it again and now it's a lot cooler it's doing it again. Starts ok then after a mile or so splutters for a bit then once warmed up its fine again. I'll be using it daily for the next few weeks so will see what it's like but it seems to me to be a problem when it's cooler weather!
