MG 1100 Sport ie 2000 problem in low rpm's

[Filipe]

Hello everyone, my name is Filipe.
I've recently purchased a lovely sport 1100 from the year 2000, I've got it with 9500 km, it looks almost new, it was well kept.
Before I bought it I've riden it for a little while in the parking lot, so I didn't notice any problem.
When I went to take it home, leaving the store in the middle of the city using the rpm range 1000 to 4000, it doesn't work properly, it "cough" and I hear some gasoline burning in the exhausts. In high rpm it goes very well.
Later I tried to ride it, and again it hesitates and cough and it isn't a very pleasant ride between open roads.
I took it to the store where they have a mechanic, they say it needed some minor adjusts in the carburation. Today I've ride it once more, but nothing changed.

The bike is stock, the only thing not stock are the pod filters (K&N).

I will try to put some pictures of it











Anyone had the some problem? What could be?

Before leaving the store I ask to service the bike with new spark plugs, change the engine oil and filter and check the valve clearance.

Thank you all.

[Devildog]

My congratulations, a very nice Sport.
The experts will respond soon (I am not one) but you have a fuel injection system, not carbs, and it may never have been re-adjusted for the pod filters. Speaking to the previous owner may help.
If you have the stock intake and filter you could re-install it and see how she runs.
Most important is finding a good mechanic, once it is sorted out you will love this bike.

[Filipe]

Thank you Devildog.
I can't talk to the previous owner, i've tried and he is unreachable (out of the country I guess).
I don't have the stock intake.
Re-adjust the ie, maybe that's it...

 The valves may be a bit tight . Any good mechanic should be capable of sorting out the problem . Fuel injection sync , TPS adjusted , maybe a tweak to adjust for the pods . Does this thing have a Power Commander , if so , most of the experts will say to remove it and establish a good base line .

 Nice bike

[Filipe]

Hello Dusty, thank you.

I've googled power commander, that is a remapp of the original right. I don't think that this bike has a remap.

Yes, I really have to get a good mechanic.

[LowRyter]

Someone told me that those bikes were susceptible to slack timing chains that cause ride-ability problems while the owners chased phantom ignition and fuel gremlins. 

I've ridden only example and it ran poorly.  The owner did lots of work trying to correct it.  A knowledgeable owner mentioned the timing chain after I talked to him about me my riding experience. 

so long as we're freeballing some ideas.........

of course Guzzi aren't meant to be lugged and should be ridden 4k+

[Filipe]

Hi LowRyter, thank you.

So you are saying that the problem could be a slacky timing chain, I've never thought of that...

If I adjust to correct slack should do right?

I know that this machine is for open roads, and i've bought it for that, but I live in the middle of the city so I have to pass trafic lights, junctions etc... and she coughs and coughs and I think that shouldn't be happening. I've tried to ride it always above 4000 rpm but it's very agressive  and it catchs the police attention  rapidly...

[fotoguzzi]

is the exhaust stock? you've opened up the breathing in with the pod filters but restricting the out flow possibly.. probably can tune somewhat for that..
you can get manuals here,
http://www.thisoldtractor.com/moto_guzzi_misc.html

there is a Fuel Injection supplement that might help but I'm not sure it covers the Digiplex ignition that your bike has, Maybe.
if it has the p8 CPU there is a trim dial on the side that can lean or richen low speed fueling.

Hi LowRyter, thank you.

I don't think the chain can be adjusted.  I think parts need to be replaced.  If you run out of ideas, you might check it.  If runs well at higher speeds I wouldn't think the timing chain would be first thing to look at. 

[Murray]

From the factory the tuning of these things were always a bit s!@t. You may be able to hunt down one of the original retuning chips, it was what inspired Cliff Jeffries to build the MYECU a few of these things had odd things like cali pistons in them meaning the compression ratio didn't to match the tune in the ECU. You can try a power commander although getting a loom to match the bike might be a bit of an issue a ducati one of similar era may do the job. You could try moving the valve adjustments out to the old t3 adjustment of .22mm?? for both exhaust and intake.

The timing chain has a self adjuster in it it is not the best however on a bike thats done so little work its unlikely to be the problem IMO, can be simply checked with a timing lamp.

[rocker59]

The valves may be a bit tight . 

My first thought, too. 

[Kiwi_Roy]

Make sure you have a steady signal going to the ECU relay, if that's dropping out due to a loose or dirty connection it won't run well, I always try to get owners to tie a small lamp on the signal to verify this, you can twist the leads around the relay coil pins or connect it between petcock fuse and chassis if it has an electric petcock.
A steady light will instantly eliminate a major portion of the wiring.
A flicker points to something upstream.

It looks like the earlier sports had the large P8 ECU

I think the later ones would be more like the 6 inch square 15M

  Filipe, your bike is a 1997 model Sport. First year of fuel injection for that model. With only 9500 km on the clock I doubt timing chain slack. My first guess would be TPS, Throttle Position Sensor. May be just a little out of adjustment or might just be worn out due to age and/or how the bike has been ridden in the past. There was a popular injection add on available back then called a Will Creedon chip. I'm not sure how it works or if it's still available. The TPS is way too expensive from Guzzi but other bikes use the same brand injection. I have a TPS from a Harley Davidson on my 01 EV. I think Ducati uses them too. They are very sensitive to adjustment.

One there must have a specialist for the M16 ECU in the late Sport. 
It has a mixture screw for idle right next to the EPROM chip under the rubber opening.
If the thing hasn't been very active, you may need to clean out gummed up Throttle Body air screws
Many things it could be.

What Guzzidad said. I would start by taking it in for a tune up and make sure they change the fuel filter and clean the fuel system. It's under the tank and I'd bet it's original to the bike. After that I'd get a ECU chip from Will Creedon. He used to sell them for $100.00 and they work. best money I spent on my '97.

Thank You, that will be a thing to check if all others doesn't work.

Hey LowRyter, I was thinking just that, the air flow trough the pod filters has almost no restriction, that could unbalance the mixture fuel/air right?
I may try to fill the empty space inside the pods with some sort of filter material to create more resistance and go for a ride to see if makes any diference, what do you think?

Thank You guzzisteve, I will dig in this documents to see if I can take out some ideas.

Hello Turin, do you know where can I check out this Will Creedon Chip's?

Ok, thank you, I'll take your sugestion to my future mechanic.

Hey Guzzidad, how do you know that is a 1997 model? The dealer said it was registered in 2000, maybe it was in stock for three years...

I'm crossing my fingers so that the problem wouldn't be the TPS, expensive stuff....

I tried to look for the Will Creedon chip online and I didn't find it for sell, do you know where can I get it?

Thank you, yours is another aproach on the problem...I'll take to my mechanic.

[Filipe]

My first thought, too.

Hey Rocker59, Thank you.

These tights valves wouldn't cause problems all the way in the rpm scale?

[pauldaytona]

Filipe, you bike has a 16M, forget all comments on other ecu's. The stock eprom might not be the best but if the rest is ok, it should run decent on it.
Since so low miles it hasn't been used much, so maybe old dirty fuel. But try to find a decent mechanic. Someone with lots of Ducati experience can do it too.
I think someone has been messing with adjustments without any clue. I think I have an airbox for it.

hello Paul, I hope you are right, maybe puting the factory adjustment back will do the trick. The moto dealer adjusted the valves before I bring it home, maybe he adjusted in the wrong way...

[pauldaytona]

maybe not the valves, but someone thought that the injection must be compensated for the open airfilters and started doing wrong things around the injection bodies. A stock 1100sport I should a decent driver.

     Filipe, the 97 Sport was a one year only production bike. They didn't make a Sport in 98 or 99 but they came out with another Sport in 2000 but it was totally different. The 97 looks just like the 95,96 carburated Sports from 20 feet away but if parked side by side you see there are very few interchangeable parts. I have a 96 Sport with 124,000 miles. I haven't used it in close to ten years now but now that I have retired from work I plan to freshen her up and let her breath again.
   The TPS isn't that expensive if you find an alternate application. I only paid $90 for mine.
    I don't know where to source a Creedon chip as I never had a need for one. Someone on this list might have the answer.

[pauldaytona]

There is only one type 1100 sport I, the 2000 model is a v11 sport, got a six speed and other clothes, and other things.

this is a 2000 v11 sport




this is a 1997 1100 sport





both spine framed bikes but very different.
