    Posted: 21 May 2018 at 07:01
Morning RSVR tech gurus, I'm looking for some help with a cut out issue if anybody has any ideas they'd be gratefully received...

About a month ago I bought an 05 RSVR Factory.  The bike is in great cosmetic condition and has just under 9500 miles on the clock, of which only 1000 have been done in the last 5 years (probably not such a good thing).  Test ride was fine, as was the 2 hour ride home in the evening after I bought it.  So far, so good...

I took it out for a longish ride a few weeks ago and after about 2-3 hours of riding I was coming off a roundabout, opened up the throttle and the revs momentarily fell away to nothing.  Opened the throttle further and it kicks back in and lurches to the horizon.  Bit of a WTF moment but all fine.  From that point on the rev cut outs start happening with increasing frequency.  Eventually the bike just cut out completely so I coasted to a stop.  No engine warning lights (or any other lights) showed on the dash and the bike would restart fine straight away.  But by this point it could do about 1 mile before cutting out again.  

It was a hot weekend but the temperature gauge on the bike was reading about 90 degrees C which seems normal enough. I thought maybe it was some kind of heat related issue so I stopped and waited for the bike to cool.  After waiting until it reached about 70 degrees C I set off and got about 5-10 miles further before it cut out again.  This time the red engine warning triangle showed so not wanting to ride on I called a recovery service.  At this point the bike would restart but even at idle it sounded weak and trembling and the revs would just fade out to a cut out after about 30-60 seconds of running.  I started the bike in diagnostic mode and it showed EFI and 0, which I think means no recorded fault?

The recovery van turned up after about 90 mins and the bike had cooled, engine warning light was gone and engine started fine.  Opted to nurse it home rather than go in the truck and have to pay for the mileage.  Turned out to be a mistake as got another 10-15 miles and it cut out whilst doing about 50mph. This time I gave up and waited for the recovery van.

One other thing of note was that the battery was on its way out when I bought the bike so I replaced it with a like for like Yuasa battery.  I've checked the battery output on the dash and it's around 12.5 at idle and about 14 when revved (this is from memory as bike is in garage now).

Googling around shows a heap of possible reasons for these problems.  I don't think it's an electrical switch/sensor related issue as the bike ran for a while without issue.  I got back in touch with the previous owner and asked if the issue or anything similar had come up before.  He said no and I've no reason to doubt him as he seemed a good guy.  The bike hasn't done much mileage in the last 5 years so he probably wouldn't have seen the issue even if it had been there.

I took the bike to a garage with a Texa diagnostic kit which can read the ecu data, apparently all that showed up was a fuel injector fault which they don't think is the problem (not sure why, presumably because the bike starts and runs).  They reckon based on another Aprilia they had in with a similar issue that it is an electrical fault, probably from a burnt out wire/connector.

Any help in narrowing down likely issues would be greatly appreciated!  At the moment the garage are looking for issues with the wiring which could last a very long time and cost $$$.  In theory I'm supposed to ride the bike up to the Isle of Man in about a week and half's time, but that seems unlikely right now Confused.

Cheers,

Billy

I'm no expert on electrics but based on a fault I had try jiggling the wires where they go into the bottom of the ignition switch as there is a possibility one of the wires has come adrift from it's solder and is making intermittent contact,this is not unknown.

I had something similar happen though mine was sometimes a complete absence of power to starter,dash although the pump powered up as usual.  You will get different effects depending on which wire is affected. My problem came to light when the bars were locked over and the harness became stretched

Problem is easily fixed though if this is the cause,though it's possibly more likely to be something fuel related like the short hose in the tank degrading due to sitting in ethanol fuel for years.

sounds a bit like the fuel pump. Quite a few go the way of working until they get hot and then start acting up. They generally won't throw a code when doing so.
 
Other possibles are tip over switch if you have tinkered around the batt or sidestand switch but those are more likely to be solid rather than just when hot.

Cheers for the pointers so far.  I plan on going back to the garage today and seeing where they've got to.  Will update the thread if they've found anything.  

The fuel pump, or some part of the fuel system, sounds logically like the strongest fault.  As the bike will run from cold for a while before the cut out happens, then it kicks in quicker and quicker, it doesn't seem like an electrical connection.  Time will tell though!

I followed this video 

The only issue you will have is removing the security shear bolt,I also dremmelled a slot across it and used a large screwdriver in the end. This could really be replaced by an equivalent size cap head if you have one handy on re assembly,I didn't so just re used the original as tight as I could get it.

I also disconnected the short harness at the plug behind the headstock and remove the harness tape,this allowed me to stack the individual wires ( flatten them )  so that when re covered they were much more flexible in the fork area.

One thing I did find was that the wire that had come adrift seemed slightly shorter than the rest probably due to the way the harness was initially laid up so that was actually acting as a straining wire.

It's easy enough to pull the harness forward a bit after re soldering so there is much less chance of this problem happening again.

OK, so as an update, I checked in with the garage today.  The conclusions they've drawn so far are:

  1. The ECU had registered an injector open circuit fault
  2. With the battery disconnected there is a high resistance reading when they check between the  injector plug's positive terminal and the battery negative terminal.
This doesn't mean a great deal to me.  Apparently that resistance reading shouldn't be there and indicates some kind of dodgy wiring issue between the ECU and the injector.  No idea whether this is correct or not, but just relaying what the guy at the garage said.

He reckons the plan is to try and chase the fault through the loom and then fix the dodgy connection/wire, or go for the more nuclear option of replacing the wiring loom.  Apparently the parts cost for the wiring loom is around £1k which is crushing!

I could go buy a second hand wiring loom from ebay, but obviously the risk there is that it has fault in it somewhere and the job would have to be repeated.  Changing the wiring loom is a time involved job (no real surprise there), so this could also be expensive.  Second hand wiring looms sell for around the £50-100 mark on ebay so perhaps not such a bad route.

In the mix on all of this is that the clock is ticking before I'm supposed to go on a 5 day trip with some friends next Wednesday, so a week tomorrow.

Probably my best bet at this point will be to arrange to beg/borrow a bike from a mate!

the injector wires are fragile at best. Look at the connectors. It is also worth removing the fuel pump and cleaning the tea bag filter. As Spoonz said this has happened to many and is cleared with a clean. Most likely never been done before.

Yeah from everything I read online the fuel pump or some part thereof sounds like a fit.  I'll badger the garage to take it apart and see if anything shows up.

Weirdly, skimming the RSVR workshop manual (https://www.scribd.com/doc/39921202/Aprilia-RSV-Workshop-Manual-2004-2008) shows on page 3-15 the notes for the "Open Circuit front/rear cyclinder injector" ECU fault as "It is a signal that can also be displayed by chance and with no actual part fault" - kind of pointless having it!

Injector errors in the ecu are very common and most often spurious. Just the process of connecting the axone can spike the ecu into throwing them. Unless they appear as active faults rather than historic i wouldn't assume they are the problem.

The injectors read something like 40k ohms measured in the way the mech is doing it which may seem high to him but is he making a comparison between injectors or just assuming it's high ?

A quick update on what has become a real pain in the ass.

I called the garage on Wednesday to ask them to check the fuel pump filter and fuel lines and the guy refused saying it would be a waste of time as it's definitely an electrical fault and he has 25 years in the industry etc etc.  No doubt it is annoying to have a customer try and overrule you, but I didn't expect this.  It would have been relatively easy for them to do the check as they already had the tank off and propped up.  I work doing consultancy work and if clients overrule my advice I just shrug my shoulders and take the money if they're still insistent once I've explained my thinking.  Anyway the guy got tetchy and said he was with a customer and would call me back.  No call came and I tried calling again at the end of the day only to find my mobile number had been blocked.  I used another phone and got through to them at which point I asked them to just put the bike back together as there would be little chance the bike would be fixed before my planned motorbike trip next week, so I might as well have a go myself and try and save money.  As they'd only done 2-3 hours work on it in nearly 2 weeks of having the bike a sudden breakthrough seemed unlikely.

Went to pick the bike up yesterday, was charged £155 to get the bike back in exactly the same state I dropped it off in. But.....they've managed to reset the odometer to zero on the bike!  I guess this is from having the bike sat with the battery disconnected for 2 weeks and running into the common clock fault.  Frustrating as I've paid them to give me the bike back in a worse condition than when I gave it to them and 2 weeks down on time.

Some sort of saving grace is that the bike had its MOT at a different garage immediately before I dropped it off at this one (they don't do Aprilia servicing but I really really wish they did!).  So I know the mileage almost exactly. The garage apparently know someone who specialises in 'mileage correction' and they would take the dash off and give it to him to restore the MOT mileage plus the 2 mile drive to their garage.  This costs £80 and I'm not optimistic that it will work or that it won't break something else in the meantime.

I'm borrowing an old CBR600 for the trip on Wednesday off a mate.  Hopefully that will be reliable as all this garage hassle is stressing me out!

I've only encountered three running issues on my Apes in 14 years, one was a cut out at random which turned out to be corroded wires in one of the wiring blocks beneath the left tank/fairing infill just behind the headlight, I think it was for the clocks, the connector had lost tension too.

Another was due to a backed out wire on another bike, from the tps

The last was a couple of years ago on the current bike, which turned out to be the stator dying, easily tested, this fault was one like yours that if the throttle was opened more the bike would lurch like nothing else. I rode the thing back from Betwys to the Wirral like I was in a rodeo, amazing I ever got it home, and is no surprise I need a new chain really,

Because it's easy, I'd do the stator check for the hell of it.

True about the injector codes, often dismissed as they're a glitch fault.

Name and shame the garage for others benefit, it isn't their fault about the clocks, it's your bike with the fault (sorry) which isn't their problem when the battery has to be off for other work, but their behaviour was sh*te.

The main reason why using bike workshops to do any work on my bikes is a last resort.
It's just too much of a lottery as to whether they've got a scooby what they're doing. 
Alarm bells would have been ringing as soon as they suggested replacing the loom. What ever the fault, first aim is to trace it and the cause.
Have you thought about taking the bike up to (the definitely reliable) AP?; you know they'll sort it.

Thats some shocking customer service no wonder you are pissed off i certainly would be. As above id check the fuel filter had the exact symptoms on my current 55plt factory once cleaned up it was fine until i developed the other fault on the STATOR so I've had both problems. I have fitted s re wind from west country windings to early to say for sure but so far so good. As for the clocks nothing you can do now but in the future do not disconnect or reconnect the batery with the key in the ignition as 5his has happened to me several times but never since following that advice. Coincidence maybe but i don't take the risk.  Good luck!

You have not had a good time.  :-(

The cut out:  did it die straight out.....as in riding, then absolutly bugger all?  Not even one cylinder firing?  Your problem was exactly the one I had last month where it ran OK for a few miles then just stopped running.  I sorted mine.  I noticed the sound of the fuel pump was slightly different so just ordered a complete fuel pump assembly, from Ebay of all places for £69 delivered!  Off a 15K Tuono Gen 2.  Not bad.  Dont be put off by milage, my original pump did 60K miles, and I still have that.

My issue was I replaced it during a build for a £25 chinese replacement.  What a load of sh*t!

Anyway, I couldnt put my old pump back in as I modified the plastic carrier for the new pump which was 1mm wider.....so had to buy a full assembly.  Took 20 minutes to fit.

I also removed my immoboliser and resoldered it....just incase it was causing the issues.....but fairly certain I had a pump problem.  Been OK since.

An easy way to drain the tank before removing: take the fuel return pipe off the pressure regulator which is left side of throttle bodies.  Put your finger over the end.  Guide the pipe out to the side and into a petrol can, then release...then lower the bikes tank to normal position.  This will get ALL the fuel out, enough for you to remove the tank and remove the fuel pump assembly.

Look on ebay...last time I looked there was another fuel assembly for about £70, which is a a good price.

Afternoon,

Apologies for the radio silence, I was off at the Isle of Man TT for a while and then got side tracked doing a minor service on the bike I borrowed as a thank you to the friend who lent it to me.

Thanks for the tip off on how to fully drain the fuel tank.  I have a siphon so was going to use that but your method sounds much easier to get all the petrol out.  I'm off at a friend's wedding this weekend and my wife has had enough of me spending ages either talking or working on motorbikes for a while, so this is going to go quiet for a bit.  Next plan is to check the fuel filter and if it looks clean enough then replace the fuel pump like you say.

The garage who reset the clocks didn't have any luck with restoring the mileage so it's stuck at near zero still.  They did write on their invoice to me that the odometer reset whilst under their care, along with the previous mileage, so I have some evidence as to the true mileage of the bike.  They also refunded the servicing costs less the cost of the diagnostic, on the basis the bike is in a worse state than when I gave it to them.  I think we'll call it quits at that as the Aprilia mileage reset bug could have got pretty much any garage except Aprilia specialists.  

Next update in a few weeks time once I've found some time to put a garage session in.

Thanks again for all the help so far.

if the fuel filters are fine you need to test the stator as mentioned as well as the current going into the battery.
It's an early gen2 so it has the two brown connectors to check. The one to the reg/rec and the one to between the v. 
LastLy check the white connector in the rear unit that joins by the rear light and goes to the solenoid and the two 30amp fuses. That can also melt

Hello again!

Long time no post I know.  Ended up going to the Isle of Man TT on my mate's CBR600F and then have been very lazy about doing anything with the RSVR since. Finally worked on it today though, so I thought I'd update what I have found so that the knowledge flows back to the forum in case anyone else has similar symptoms.

Since the IOM I went for a "wishful thinking" ride out with a friend to try filling it with petrol once the cut outs started to see if they were due to the fuel pump overheating somehow.  My theory was that the cold fresh fuel would cool the pump and the cut outs would stop fro a bit.  That turned out to be rubbish and I ended up having to limp home. After that I decided to drain the tank and look at the fuel pump and filter.  I siphoned the fuel out a while ago and finally found the time today to continue the job.  

Taking the tank off and getting the fuel pump out turned out to be surprisingly easy.  I disconnected the 2 bleed tubes and then there was enough slack in the fuel delivery and return lines to be able to flip the tank over and unscrew the pump and pull it out.   Straight away I could see a load of 'brown sugar' type sludge around the base of the fuel pump.  Looking in the tank I could see it swishing around in the dregs of the petrol in there as well.  Jackpot!

I tipped the last of the fuel out into a petrol can using a funnel with a filter in it, and the filter got so clogged the fuel wouldn't even drain through it until I stirred it up again.  The "tea bag" type filter inside the fuel pump assembly had more of this brown sludge on it.  I ran out of daylight today but I look forward (almost) to cleaning off all this brown gunk and putting it back together.  If I can figure out how to upload photos to this forum then I will do.

Once the bike is back together I'll let you know if this cures the cut outs.

Cheers,

Billy

Congratulations it sounds like you've found the cause of your problems Clap

I had a similar thing happen last time out in very hot weather with a low fuel level,I've been meaning to strip the tank and check for this but it can wait till over winter now.

Yeah, worth the work to strip it out - that must be it I would have thought. So how many miles have these bikes done that end up with this problem?

Not a lot. Maybe it's to do with old fuel standing for long periods?

possible hard to say without knowing the history. For me it was a result as I bought it as a non runner and got the bike running again for the cost of a second hand fuel pump and a new filter. I've also had a Gen2 with 24k which was still on the original filter but had been well maintained. As we all know keeping on top of maintenance is essential whatever bike you own.

just a thought while you are in there make sure it breaths your fault sounds a bit like the breather is blocked it runs until it vacuumed opening the fuel cap when it died would have told you that since air rushes in

Just a thought

Evening, I finally found some more time to work on the bike.  I was hoping that it would be up and running after today's effort, but no such luck!

I fully removed the tank and cleaned it out with hot water and then left it to dry.  There was still quite a lot of dried up 'brown sugar' type crap in there which is all gone now.  I used a toothbrush and a little bit of warm water on the fuel pump and tea bag filter to get rid of all the gunk on that.  I also used a bike pump to blow air though the breather tubes on the tank to make sure they weren't blocked. Then I put it all back together, got 5 litres of fresh premium petrol from the local garage, filled it up and tried to start it.

At first it attempted to turn over but sounded kind of like it was jamming.  I figure that this would be due to there being some air in the fuel system following a full drain and that it would take a couple of goes to get fuel in. No such luck as following 'key on' I can hear the whining of the fuel pump but when I press the ignition button I now just hear a clicking from behind the seat.  I've tried starting it with the bike in neutral and also in gear with the clutch pulled in and side stand up but just the same clicking and no attempt to turn over.

When I try with the bike in gear and side stand up with clutch pulled in then the neutral light flashes at the same time the click sound happens.

I thought maybe the battery had lost a bit of charge given it's been stood for a while.  Hooked it up to an oxford oximiser trickle charge this evening and it showed as 'green' before any charging had taken place.  I have to run an extension cord out of the window of the house to charge it so didn't leave it to run on trickle charge as the house would become freezing.  I'll take the battery out and start charging it tomorrow.

Searching the RSV forums shows a load of different reasons why the bike might be behaving like this.  If anybody has any strong ideas as to what might be the issue in this case then suggestions welcome!

flat battery or faulty starter relay, when battery fully charged try it again and if still just a click try bridging the terminals on the relay

Yesterday evening I switched the batteries over and the starter motor was attempting to turn it over again, which is good news.  Bad news is that it wouldn't start.  I tried putting it into the highest gear and heaving the bike to get the piston positions to move, tried again and more of a sound of starting but still not quite catching.  Kept trying but then battery died again.  That battery was 5+ years old which is why I replaced it, so now the 'new' battery has been on trickle charge overnight and all today.  Will fiddle around in the dark late and see if I can switch it over and try again.
