Please help - Engine stops and won't start - 2006 RSV R with 9000km on board

[Santon]

Hi guys,

I'm posting for a friend of mine who just bought YESTERDAY a 2006 Aprilia RSV R with only 9000km on board.

At a closer look after buying it we discovered that the battery top plastic cover was loose and some plugs to the battery cells were off. We inspected the battery (by eye ) and found that it had very little water in it. We bought a distilled bottle of water and added into the battery.

After that, he fixed the top cover of the battery with double side adhesive duct tape and he went to a ride.
After just 20 km or so the engine suddenly stalls/stops and a pop sound came under the seat. The bike won't start anymore. The starter workes. The engine rotates but no engine start.

After inspecting the battery again he found that the cover was blown again. He replaced the battery with a new youasa one borrowed from a friend but the engine still won't start.

Please give him a hand or a suggestion to this problem. The bike is very new.... and he's very very very disappointed and sad .

Thanks a lot

check tip over switch under seat, and make sure the battery is a right one.
any codes on the dash?

Symptoms:
- bike cranks fine but doesn't start
- no popping in the exhaust, backfire or anything else
- air is coming out of the exhaust so sprag is engaging, although I would've expected a stronger smell of gas out of the pipes

What I did/checked:

- fuses (2x30 amps near the batter and the ones under the right upper wing/fairing) all good (with multimeter)
- connections, nothing lose near the battery
- tilt over switch, mounted correctly, tried starting the bike without it, EFI stays on but same symptoms
- no codes on dash
- side stand switch, if in gear bike doesn't crank, so I guess it's not faulty?!
- fuel pump - primes 2-3 second when I put the ignition on
- let bike sit over night in case it's flooded, nope...

What we will do tonight:

- hook it up to my car's battery and see if I have a spark and if injectors are working.
- have a beer and look at how beautiful she is

So if you have any ideas of what I should check, please let me know

What to check next?

Thank you guys.

Stupid question maybe...but...is there fuel in it?
Pull a plug and check for state of plug (wet?) then look for a spark.
At least then you will be able to narrow it down to spark of fuel.


A lead acid (water) battery....???
I can't remember the last time I saw one of those....deffo not standard fitment on an RSVR...theys are generally sealed gell/acid or GM these days...

yeah must be battery probs, these v2's need BIG cranking power matey

defo change the battery to a gel one. if you are adding water to a battery which already gel filled you will get the results your having!

 

[Santon]

Thanks

Yeah,

The battery sux(it's a dinosaur), it's a lead-acid one with maintenance(needs water completion once in a while).
There is fuel in the tank.
Will check the spark out of the plugs. Hopefully there isn't any so that we can narrow things down.

Keep you posted.
Thank you.

Side stand switch playing up , doesnt allways light up on dash when they play up
The side stand switch actually has two separate switch elements. One just controls the dash indicator light. The other controls the ignition circuit. The switch grounds one circuit or the other to enable it. Just because the dash light goes out doesn't mean the ignition is enabled. The only way to check that is to bypass the switch. The bike will not run in gear if the side stand switch does not enable the ignition.

The neutral light switch will tell the system that the bike is in gear before the gears actually engage.
Bypass the switch

Great !!! Added to check list. Thank a lot.

I've just tested for spark at the lead, and I have spark. So that means I don't have gas. I've looked down the butterfly opening and I cannot see any gas going in.Fuel filter and hosing are ok.

I've measured the input to the right mounted injector with ignition on and i get readings up to 8 volts. I've also measured the resistance of the injector, somewhere aroun 15-16 ohms.
so who's telling them not to fire? camshaft pos sensor?

Suggestions?

Blocked tank outlet? blocked breather pipe?

Problem SOLVED.

It was the tank fuel hose. Had a hole in it
Hurraaaay !

Thank you guys for suggestions. Took every one of them into consideration. Thanks again.
