This morning my X wouldn't start. The startermotor turns normally, but the engine won't fire up...
I know there could be many reasons, but where to start?

Center stand down, side stand up?

Got it working again. No idea why it wouldn't start. Hope it will last

Won't start again!
When starting the sparkplug is quickly flooded so it wont't start en meanwhile the battery runs out of juice. I dried the sparkplug and recharged the battery and after that it would start normally.
This morning wouldn't start again >:(
When starting the battery icon on the dashboard lights up after 10 seconds. I read on the manual that this means voltage is below 11 volts.
The battery was installed january 2014.
Need ideas guys.
Thanks

I have this issue with my 2010 EFI. I just bought a new battery. Charging measured at battery while idling no lights on, 13.15 volts. I am told it should be 13.95 . I used to own a grandchild 2006 and the choke was seized solid. Check these mentioned things out.
-
I am hoping the new battery will keep the morning cold start issues at bay for a while.
-
I also have trickle charge on during winter here in south Africa.
Scoot parks outside under net gazebo.

EFI bikes will have lower charging at idle because it has to run the fuel pump and injectors. Anything over 13v at idle is good. Also the x500 is horrible on batteries, only really get a couple chances to start it before it starts to crank weak.

Mine has a carb. Guys, is my battery dead?

does it crank over?

yes, absolutely

yes, absolutely
Then the battery is a OK

Someone explained to me that if there is not enough juice to create a strong spark the sparkplug will flood etc. etc.
Is there a logic in that?

The 500cc engine is HUGE, so if the battery has enough grunt to crank it over, it has enough to spark just fine. You'll know if the battery is bad on the 500 because it cranks very slow to almost no cranking.

Okay, but what could be the problem then?

Did the bike sit all winter? If it did, have you flushed the gas and cleaned the carburetor jets out? This is where I would start. If it died while driving or whatever, I've seen the fuel pumps go bad on the X500. Has the bike ever tipped over? It has a tip over sensor that will not let the bike start, I've disabled one before on a customers bike that he was constantly dropping. These are just a few options. Check for spark first, then go from there.

Thanks voor the tips:
Did the bike sit all winter? partly
If it did, have you flushed the gas and cleaned the carburetor jets out? No, but I checked the carb. There's lot's of gas
If it died while driving or whatever, I've seen the fuel pumps go bad on the X500. It only has starting problems
Has the bike ever tipped over? It has a tip over sensor that will not let the bike start, I've disabled one before on a customers bike that he was constantly dropping. I did turn over the carb itself several times to reach the thingy to tune the CO2. How could this sensor be disabled?
Check for spark first, then go from there. Impossible to reach the spark plug without special tools. I already ruined the sparkplug cable once. I will have to find good tools first
When starting the battery icon on the dashboard lights up after 10 seconds. I read on the manual that this means voltage is below 11 volts. Does this indicate anything significant?

The tilt sensor is located in the nose of the scooter, and the ENTIRE bike would need to have tipped over to set it off. If the bike sat for more than a month this winter, I would take the carb totally apart and clean it out. You have to reach the spark plug cap with needle nose pliers, and pull it from the cap body NOT the wire, then use a long extension with a spark plug socket to get it out. Crank the bike over with the spark plug touching the frame and look for spark. The battery voltage will be far below 11v while cranking, this is totally normal. I'm guessing this issue lies with the carb being clogged.
-
Repaired!
It was the sparkplug-cable.
Second time btw. Must have something to do with the fact that the cable is under friction because of the engine block being part of the suspension etc.
-
The story continues :(
Still starting problems. I have a feeling it may have something to do with fuel. There is either too much or too little.
When it wouldn't start I loosened the idle screw on the carb and it started right away. What does that mean??
Can anyone tell me the default number of turns of the pilot screw? Is it 2,5?
-
I'm having the exact same issue. :'( :o
-
I played with it somewhat this afternoon thinking it's the fuses. In playing around with it I noticed one of the battery cables was rubbing against the plastic case the battery sits in. It started right up with full power when that plastic piece was off....put it on, nothing. So, I think I just may need a new battery cable...or a better way to hold the battery in place.
Ideas?

Guys, I'm desperate. It's been weeks now that I'm battling this problem that my Xciting 500 (carb) has and I can't rely on it a all. I prefer not to bring it to the repairshop as I'm certain it will cost me an arm and a leg and I will still not be sure if it is the final solution as changing the sparkplugcable by the repairguy was not the solution the last time.
The problem is that it starts very arbitrarily and I can't find a pattern... When it does start it picks up immediately without hesitation. When it won't start I smell gas but it won't fire up. Flooded?
This is what I did so far:
- replaced sparkplug, sparkplugcable and battery.
- took carb out and checked inside for flaws. Put original 118 jet back. Reset mixture screw to 2,5 turns.
- cursing
What can it be? Electric of Carb?
Pro's: please let me know any (serious) ideas you have.
Thanks.

There may be a pattern in the starting problem: when (if) fired up and run for at least an half hour, a couple of hours after or the next day it often won't start.
Any idea is welcome!
Thanks!

Sounds like you have an intermittent cause like a wire grounding or opening. This will be very hard to find and it would cost ya big if you have a shop do it because it takes a lot of time. You will be the best tech for this job. You may have to remove a bunch of plastic to do this. Already mentioned the plastic battery clamp, I think, so start there. Take your time and get your mind right and you WILL get this. Keep posting what you find and we will all chime in with ideas.

My bad. Hound had the battery clamp/cable but start there, anyway!

Guile, what news re your carb XC500 starting woes?
-
This is an interesting topic for me, since my XC500Ri EFI also had major starting issues, now resolved. Mine has no carb, and solution was an electronic device of some kind, not sure what.
I hope you get it sorted soon, Guile

Was it a coil of some sort?
-
I will get the exact part name from the shop and let you know.
-
For the EFI model, you can get a modified ECU, but in my case it was a combination of rectifier, starter motor, solenoid and relay.

In what way did your X did not start? Did the starter motor turn but was the spark unstable or missing?
-
While battery had power it would just crank, now and then a splutter. Battery eventually faded due to multiple attempts at starting. Occasionally it would start. It was suggested that since ECU must be getting full voltage to run all the electronics, when battery fading, not enough power left to spark, crank, and keep ECU at operating efficiency. (so ECU was brain dead when battery was fading).

Thanks for replying.
The problem still hasn't been resolved. The mechanic now wants to move an electronic wheel closer to another part so the spark is stronger (I don't know what I'm talking about). He needs to open the right side of the engine for this.
I'm frankly not at all reassured by this approach.
Please people, ideas!
-
I know which part you are referring to, also don't know the name. As far as I am aware, that part has not been replaced on mine. A mechanic I know has said that that 'wheel' can loose efficiency after a while, and should be replaced, or rewound. Moving something closer to get improved spark is going beyond cost-cutting, just get the proper part, in my opinion.

I also installed an extremely high end battery, Motobatt, with high CCA of 240,more than traditional battery.

What about your auto choke? If it does not start after 2-3 tries, battery is going die, and it will likely be flooded. I got mine started a few times, by drying and sanding he spark plug gap.

Guys, I started this thread almost a half year ago and I have been struggling with my X since. It would only start very arbitrarily. I tried everything and it cost me a lot of money. BUT I found out recently that when I turn the key and wait about 10 seconds until a soft ticking sound stops, the engine starts... Is this the autochoke / fuelpump?
So the good news is that I know now how to start the damn thing, but what needs to be repaired?
Please your suggestions
-
That will be the electric fuel pump. I had some success by doing a full throttle just after fuel pump is primed, and then immediately starting. The Motobatt battery I mentioned before will give you more starting attempts, and less chance of leaving you stranded.

Do you mean the pump needs to be replaced?

Makes me wonder how Wayne is getting on with his new to him 500. ??
Wayne, time for a full new owner's review! :-)

I fail to see relevance here... ???

Re starter needing to be replaced. I am not saying that. Since it is priming, it should be good. EFI models, fuel pressure is more critical, but for carb models, float and needle/seat issues are a possible problem area. I mentioned my starting procedure when I was also having major starting issues,which had some success.
I learnt recently that here is some mechanism to do with the cams that releases cylinder chamber pressure for a second just to ease starting. I don't know if your model has that feature.
The bike shop I used for repairs also only seemed to find out about it while working on my scoot, and then also, when I was there another time, I saw a xc500 stripped which the mechanics explained had that exact problem.
Hopefully your starting procedure will keep doing the trick for you, but dead of winter I would strongly recommend that high end battery I have mentioned a few times now.

Boy, what a hassle! New bike, too. The thingy the "mechanic" wants to reposition is the CPS or Crank Pulse Sensor. This would be valid if spark was intermittent. Is he SURE this is the problem?
Karl
-
He can't move that part closer, it is plugged in in line with/after the stator/generator. This part could be weak or breaking down intermittently? A new one may do the trick. If he has the right side cover off, I would replace the statot/generator at the same time. This is the charging system. Mine started to go bad, and took a year or so to finally die. It's 60 some bucks, I would replaces it. :-*
-
The part I made reference to is the decompressor cam. It is a mechanical part.
