Redline's to early

[romeo-corsaro]

Hello everyone, got my corsaro veloce last week and been riding quite a lot, on the dash it redline's at 9,500 rpm and what I have noticed is mine kickbacks at just over 8,000 rpm?? I looked through the handbook and saw the part on the rpm run-away speed threshold (the picture in the book shows 100x100) I adjusted this the maxium which is 105x100, thinking this would solve the early redline limit I took it out but still just over 8,000 rpm it still hit this limiter? I once had a aprilia rs250 and on that it was so easy to adjust the redline you could just move the needle to where you wanted it but with this so far I am struggling to work out how to adjust this early kickback? can anyone help me with this? thanks a lot, Ryan.

Hi,
the runaway speed setting affects only the red light that comes on when pre-set RPM threshold is reached. It is only indicative and just for you to know when to shift. I find it quite useless, because it is hard to see during day...

The limiter issue you are experiencing must be something else. Corsaro have 3 versions: Avio, standard and Veloce. The Avio had reduced power and it was done by changed fuel mapping and by lower maximum RPM. Is there any way you could have Avio mapping in your ECU?

hi franco, oh I see ummm well yea you may be right there but it is a veloce all the handbooks and logbook says veloce and it has the termi's as standard and has all other veloce trates, but yes for some strange reason it maight a the avio map.. well thankyou very much for your help and I will look into this some more, I will speak with you again soon, thanks

Hi Ryan,

Firstly welcome to Corsaro ownership and to the Morini Riders club. I'm sure you've already found what an absolutely stonking machine the Morini is, and you've found the right place to come for advice...

As franco82 says, the runaway speed setting is merely an upshift light and more or less pointless.

Your veloce definitely has the proper veloce ECU (the standard one, not the race-only one). I know this because the bike used to belong to my dad (It's the one he rode to the factory in 2009, and featured in last November's Ride magazine (mine's the yellow one). We never had any running issues at all with it, so I'm surprised to hear you say it's missing something at the top end.

Have you removed the baffles from the exhaust? if so I'd advise you refit them- the de-baffled system needs a race only ECU (or a remap at a specialist), so I suspect it's running out lean and misfiring. If it is then you could seriously damage the engine.

When Performance Bikes road tested a Veloce in Sept 2009, Three Cross supplied a de-baffled bike with the race ECU fitted. The bike was too noisy for Bruntingthorpe and so PB couldn't fully test the bike- that article said that to put the baffles back in you have to change ECU, so the same is true in reverse...

There are various places in the UK now who have worked on Corsaro re-maps so if you wanted to run de-baffled then i'm sure somebody on the forum could advise where is best to go.

Try it with the baffles back in and let us know if you still have running issues,

Best wishes,
Tom

My Corsaro (non-Veloce) has a 9,5000 redline BUT the handbook states that at no times should 9,300 be exceeded. I believe later models may have an amended tacho (anybody?).

Anyway, if you are using 9,500 rpm on the road you will be, er, going a wee bit quicker than the plod would prefer on Her Majesty's highway... in 2nd gear! Yes they are great bikes, but I prefer to ride mine in higher gears and enjoy the lovely torque curve. Top gear 70 to er, 71 officer, in a few seconds for quick overtakes, perfect. Love the way it will pull from 2,000 rpm, instant response anywhere in the rev range. (and 40 - 45 mpg!).

regards,

Old Fart.

ahhh hello tom yes ive waiting to speak to you, yes I brought yours dads bike he said to try and make contact with you, thanks for the warm welcome, well I am puzzled then because my very first ride on it I had the baffles in and it did then! and still does it now the baffles are out :/ im just not sure why its doing it, I know you don't need to take it right up there but I was heading towards at least 8,500rpm but before I got there at about 8,100/8,200rpm it just hits like a invisible rev limiter? its not a massive issue but I would like it to be able to do what morini made it to go up to, as far as the baffles out go it seems to run better with them out, a little bit more power sounds a lot better! and doesn't misfire or backfire or cough or splutter or anything so yea I never thought it would be an issue, also being fuel injected I assumed it would correct itself a little and to be honest its not a hugh change i.e haven't fitted different performance parts or using a higher octane fuel, just removing the baffles but if you say that then maybe I should take note from that, also one more thing I thought the voloce had a ohlins rear shock but I cant see any ohlins markings and in the handbook it says its a sachs :/ ? would do you make of that? and thanks for your input mickey moto thanks to everyone so far very impressed by the whole forum regards, Ryan.

[romeo-corsaro]

also @mickeymoto yes its lovely to ride its the first bike to put a full grin on my face! so comfortable and fun! ive ridden many twins in the past (Honda firestorm, aprilia rsvr, sv 1000, cagiva v-raptor) and I also have a mondial piega with sp1 engine but the corsaro just seems so much better to ride and have fun on also being a 1200 its just so grunty! big smiles haha.. and not to sure about later models but mine 100% says 9,500 redline

[franco82]

romeo: As I found, Veloce was not fitted with Ohlins from the start of production. So it should be one of the first series with Sachs...

[romeo-corsaro]

hi franco arhh I see well that clears that up then, wish mine did have ohlins haha but oh well not to worry, thanks

Hi Ryan,

Any luck with the misfire? Did you try it again with the baffles back in?

One other thought- are the gear indicator and speedo working ok? These can be tempromental on these bikes. The speedo problem is normally caused by a faulty wheel speed sensor on the rear wheel, or by incorrect shimming of it, and manifests itself as dropouts in the displayed speed, and sometimes spike to huge numbers even when at a standstill! The gear indicator on the modern morinis has been known to display the wrong gear, or miss gears or just show '--' the whole time. Also, is the tacho reading correctly (what rpm are you registering at warm idle, and what mph in 1st gear at 1000, 2000 and 3000 rpm?)

I did have a hard cut issue at 8-8500rpm on my first corsaro, and this was present at a time when I had all of the above issues! My thinking at the time was either if the gear indicator isn't working and the bike thinks its in neutral or a low gear there may be a lower rev limit whichs being hit when riding. Alternatively if the tacho isn't reading right, you may actually be hitting the true redline at 9,300, but just not know it. I can't say for sure what the fix was as 3X serviced the bike and performed some warranty updates shortly afterwards and I never had the problem again. I know your veloce had all the updates done sometime in 2009 so i'm pretty certain it won't be an update issue on your bike.


The notes I made at the time I had problems with my corsaro are below:
20/05/08
engine ‘hard cut’ / misfire at 8,500rpm in 1st and 2nd gear. Repeatable (possibly the first time I’ve taken the engine to 8500). Quite ferocious. Spoken to Pete Scott @ 3X who will see if one of their bikes does it.

21/05/08
Starts fine. Cut out after a short ride (engine 18 deg) started again ok, Running fine.

Couldn’t get it to ‘misfire’ at 8,500 again. Gear indicator working normally. Wonder if there is a neutral rev limit which I was hitting on 20/05/08 when the gear indicator was playing up?

21/05/08
Started fine, gear indicator mal-functioning again (wrong gear indicated or flashing between neutral and gear)

Engine cut out between gears with a large afterburn. Difficult to restart.

Tacho reading incorrectly- anywhere between 0 and 700rpm idle, occasionally reading ~1200 –Begs the question does tacho read correctly while driving, and is tacho engine speed signal the same as EMS signal? If so could explain some of the poor running.

8,500rpm rev cut present again. Possible issue with the engine speed being wrong or neutral indicator intermittent (does EMS have a hard cut rev limit in neutral?)

27/05/08
Gear indicator still malfunctioning. Rev counter still reading 0 at idle occasionally. Roadspeed in 1st gear at 1000, 2000 and 3000 rpm: 17mph, 22mph, 28mph.

30/05/08
Hard cut at 8,500rpm again, tacho then step changed to 8,500rpm before dropping to 3000.

After a 50 mile ride (mainly dual carriageways) The bike would not restart after refuelling (engine temp 79 deg C.)

3 cranking cycles almost flattened the battery. Spoke to Pete Scott who suggested switching the relays over. Still wouldn’t start but battery voltage 11.5V dropping to between 6 and 9 on cranking.

Steve from 3X jumpstarted bike, rode 60 miles to Portishead (M4, M5) Tacho completely wrong- reading 3,000 rpm regardless of gear at motorway speeds, but responded normally if you revved the bike with the clutch in.

Speedo jumping by +/- around 10mph. Neutral indicator flashing on and off and indicated gear jumping around.

Engine response not as good as normal and quite bad shunting at 60mph. Running hotter than normal.

You can test it on top speed too. With limiter kicking back on 8t rpm, you will have problems reaching 220km/h (138mph), with correct limiter set over 9t rpm you will have no problem going over 240km/h (150mph). You can test it on 1st gear if you want to avoid speeding. On 1st the corresponding speeds will be 82km/h (51mph) and 95km/h (60mph).

These speeds are the ones showed on correctly working tacho. You can correlate them with GPS measuring using smartphone and some free app for logging (google traces on android works perfectly fine for example). Just keep in mind, that the near-real speed (GPS) is about 10% lower than the ones showed on tacho.

Hello Tom, put the baffles back in (to my sadness lol) it never backfired though with baffles in and out.. Wow that's a lot of info haha thanks, well the gear indicator works perfectly fine I'm really happy with that most accurate factory fitted system I've had the pleasure to use so that's ok and the idle works fine on tickover and when running.. And speedo works fine as well, but you guys might be right by saying that maybe the rev counter does read abit lower at higher revs and when it hits the 8,300 limit it might really be the 9,500.. Also I have done 140mph on it and it did not hit the limiter and still had abit left so that makes me think that theory is correct, everything works fine, I can't remember what the idle revs are but it seems very normal because I never was alarmed by unusual high idling, and yes your dad told me it had all the updates so that's a good thing well like I say maybe it is normal but for some reason the needle says 1000rpm lower than what it really is. Can't wait till next week though I've got lots of carbon fibre goodies coming
