Tried several times today and no joy starting her up.

The only other time this happened I left it an hour tried it again and started first time.

Battery fine engine turning just won't fire.

Any suggestions? Rode it Wednesday no problems?
 
No alarm. Tried it again just now & still no luck. Hopefully it'll start tomorrow. If not? Don't know.
 
Not yer kill switch,is it?Just a thought.
I would charge the battery up overnight.It may have enough oomph to turn the engine over,but not enough to power the injection system as well.
 
Mine does that on a very rare occasion,it used to do this a lot but would start after it had been left a while, it got right on my ****, gear on ready to go then f all would happen, i changed the starter solenoid,put on a 14 volt battery, it has only done this once since i made the changes and that was after i'd washed it. but it messes with your mind a bit, what if it wont start after ive parked up , been ok since.. hope that might help you..
 
crank it over with the throttle wide open (trust me)
the extra air flushes the cylnders out
then when it fires let it rev at about 3k till she warms up ( gotta get warm to clean the plugs up)
done it loads of times
 
Tried it with throttle wide open yesterday with again no joy! Going to try it in a bit.
 
Doing my head in. Still won't start. Going to phone RAC as battery feels like its dying and hopefully a more powerful battery will do the trick.
 
take a rear plug out and see if it is fowled ,if it is your gonna have to take em all out and clean or replace
listen to see if the fuel pump is priming
when you crank it is there a message on your dash saying no start ! if there is your tip over sensor has fallen over or faulty,
check if you have a spark by puttin a plug a plug cap and cranking it over
after that your gettin down to fuel pressure checks and more involved diagnostics
verry rarely the fuel pipe blows off in the tank and causes loss of pressure but you need pressure tooling to check that (or drop the pump assy out to visualy check)
99.9% of the time with these its purely fowled plugs and they clear when you crank them with the throttle wide open or new plugs
ps are you getting a bad banging noise from the generator area ie is the starter clutch dissengaging ?
 
Can't even get hold of RAC too busy.

Fuel pump is priming, no banging noises or anything. V annoying. Being a numpty with the spanners not going to take plugs out etc.
 
My 04 tuono has done exactly the same thing!!! couldn't get it started friday morning, tried throttle fully open but only got a small backfire! engine spins over ok no noises or error messages! samething RAC too busy to pick it up! got my local (Yamaha) dealer to recover it, they are going to have a look tomorrow but I bet the bloody thing stars after its been standing! It wouldn't last weekend after washing it but did the day after! I have fitted a new starter relay the battery is in goog condition(according to my optimate) and the plugs were new 6 months ago! As much as I love the Tuono the unreliability is piss poor! I ran a Fireblade all through last winter (the only time it wasnt ridden daily was when snow was lying on the ground!) and it NEVER let me down! The most you should have to worry about is your bike being attacked by road salt not if it will even start! at this rate she will have to go, a speed triple or Z1000 is looking a very attractive prospect now!!
 
Woo-hoo! Started first time just now. Tried it one last time before I tried calling RAC again and fired straight away.

Why wouldn't it do that on the weekend I wonder?

Anyway I couldn't have drained the battery much repeatedly trying to start it on the weekend - I checked using the bike battery reading before I tried to start and it was 10.9V. So I obviously drained it a bit. After it started I let it idle for a while until warm and then blipped it a few times etc. Turned it off checked the reading again and it was 11.7V.

Q - So why the flipping eck did it fire first time today with a weaker charge than on the weekend? It surely can't be that its not quite as cold today as Sat or Sunday!!??
 
Bit weird STiX. Mind you without riding it you won't have charged the battery at all so why it should show 11.7V afterwards is beyond me as theoretically shouldn't it show less?

I tried this before I got an optimate and drained the battery completely on my BMW. Saying that the BMW was nowhere as bad at draining the battery as the Tuoldo.

PS hope you're going to make an appearance up Abergavenny some time in the spring fella for a blast
 
Definitely will in the spring!

I left it idle for about 20 mins - thought that would charge it a bit tho?

I'll start it up more often and get another solariser - think I fried the last one by forgetting to unplug it before starting the bike :(

Because they just do. It's an Italian women, so it's fiesty, temperamental, and occasionally doesn't want to know. TBH you flooded it.

BTW a fully charged battery reads about 13.5V. Get an optimate (or similar) on it.

Charley - if the internal fuel link pipe pops you can hear it spraying if you open the cap on the fuel tank, I think the pump carries on running rather than it's usual couple of seconds as well.

No mate you need to ride it to charge it. That's why peoe run their batteries out by starting bikes without riding them. Best just leave em.
 
Batfastard - tried to start it several times on the weekend. Left it hours between trying in case I did flood it.

bay_1472 - fair enough didn't know that. Just bought another Solariser so battery should be fine.

Its not the battery I'm so concerned about as that is obviously fine. Its the fact that I had ridden it Wednesday and with a full battery it just would not start on Saturday.

Oh well as Batfastard rightly says - its Italian.
 
Oh, why would a fully charged battery read 13.5v? Its a 12v battery is it not?

When it's running its charging the battery @ 13.5v. Surely when it's not it can't go over 12v though?
 
hi stix, thats why some of us have got 14volters on ours, the 12 sometimes aint just man enough, especially with an alarm fitted + some cold weather.. since i changed mine over its been a lot better.. the alarm can sense drops in voltage [meta v3] and would play up, now with the engine running it reads 13+ and no more alarm problems..
 
Oh right. Mines been changed so perhaps it's also a 14 then. Wouldn't start again today voltage at 11. Ordered another solariser tho so hopefully when it's fully charged it'll be ok.
