Hi guys! I need your help. My Vdue starts well with a full charged battery. When I stop it and try to start again seems the battery is discharged. I charge the battery and then starts again, but only for one time. I try with another battery and then the same problem. The two batteries are in good condition because can start many times a SV650. Do you know wich could be the problem? All the saturday for nothing... Thanks for your replies. Bye!

PD: Sorry for my english...

Try the main earth , generally on the left hand radiator mount, or try the actual contacts in the starter toggle in the right hand switch gear.
Also try just holding starter toggle switch down for longer as mine seems to have a delayed reaction to the start function. Take 1 or 2 seconds to realise the button is depressed.

Start it up and check charge rate

The starter motor on my bike start turning right away on the first try, if I try a second or third time I need to hold the switch for 1-2 seconds before it reacts.
after 4-5 starts, I get the low bat message.
my bikes is always plugged on to Ctek chargers all the time to save the battery.

You can ignore the "low Bat" warning note that comes up on the dash.....with a decent newish battery theres still plenty of grunt left over lone after this warning message comes up........my battery charger can indicate "strong battery" and voltmeter says so also...yet low batt warning can come on after a few failed start attempts....I usually key off the ignition and leave for a few moments for the ECU to reset itself on warning messages.....think the Low batt warning is programmed to come on over a time issue of non start rather than a warning on the battery itself.........start button not working for a few seconds is a good thing.....Older Ducati style start buttons on older Bimotas had a tendency to short out if you kept them pressed for too long, and that meant a new starter button assembly......at least on the Vdues it seems to auto cut-out to stop this happening....if an issue just use the key to reset and start again

I've sort of learned all this over the last 10 months since having my Vdue..which even if it isnt ridden every week (although I try) it is started every week........It was the only bike I rode to the Mcr Bike show...despite the rain bouncing off the roads on the way down...and all with no problem......

Great, thanks

Hi all I have a problem with starting the new bike too the sun has even gone in as it's taken that long.
It started with the choke warmed it up with constant small blips for 30-45 secs, then choke off an continued to warm up to 40 degrees, then Stopped. Won't re start. Checked fuel, plugs, oil etc. left for a bit. Tries to fire for 1sec then nothing. Repeat half a dozen times, now feel dispondent. Outside temp is 14 an cloudy. Idea's please

Petrol tap closed?

After more time, I've narrowed it down to the battery or charging system. As with the trickle charger back attached it runs well. Even with the lights on or the electric fan. Without it it dies.

Are you actually riding the bike on the road yet Matty? re insurance posts etc etc.......I always get myself ready and then start the bike...once it revs cleanly after 20 seconds or so I back off the choke completely and then ride it........otherwise you will be draining the battery if just starting and letting it idle without riding it...........Battery could be 17 years old? And hence not up to the job of holding a charge?? Does "Lo Bat" warning sign come up on the dash when starting it?

[Matty82]

Hi 2bims, I didn't want to but you know sometimes you just get the erg to ride your bike, ha. Bad I know but.... You're dead right by the sounds of it. I normally run my 2stokes up to 60 before riding them, no-one likes a cold seize they all sit fine till we're both ready. How come the stator/ copasator setup doesn't seem to function. The battery should be good as it's ALL new but will double check tomorrow.
Tell me more about a 20sec warmup an then ride. Is this the best way or is it the only way.
Oh ya when I get fully sorted an out are you up for a ride

if you start getting mis fires on the starts you might want to check your sprag clutch...
both me and Nige had this problem many years ago.
trying to keep starting the bike with a low voltage/flattish battery will knacker it...
