Bar risers - again!!

BrianC · Post by **BrianC** » Fri Jun 15, 2007 1:38 am

Thanks for the tip on Gerhard's files. I want to raise and also pull back my bars, has anyone tried this? The spacers would be bolted (down) to the triple clamp, extended back (50mm approx) and bars bolted (down) to the risers. Shouldn't be too hard...for an expert (not me..).

Re Staintune pipes...do these require a special chip? My 907ie has Staintunes - don't know if any later chip's been fitted.

Re cruise control - I just need one to give my right hand/wrist a spell for a moment or two, not to leave on for any extended time.
Cheers, Brian C.

I find the drive position quite comfortable, so I'll not change it.
No matter, if you want only raise the handle-bars you can do the spacers, but if you want furthermore pull back them, I think is easier make a new upper clamp fitting a Monster's type handle-bar, or welding two raisers on the stock upper clamp.

About the Staintune: all the open mufflers require a richer mixture, or the exhaust valves could go burnt.
On the P7 ECU there is a potentiometer to richener the mixture, but I don't know if it's enough only richener the mixture trimming it or it needs also to change the chip on the ECU.
I would also like to know it, because I have a mod chip and I'm guessing if fitting it or not with the stock mufflers.
No matter, to find out the chip, you have to open the ECU.
The stock chip has a label "Ducati 907ie -023-" on to the european bikes, or -023U- on the USA bikes.

Ciao

P7 ECU potentiometer adjust ONLY IDLE MIXTURE in lower rpms! Anyway it should be adjusted to close 4-5% ratio measured by good fuel / air ratio meter and If U put Lambda sond to end of exhaust, remember then close another exhaust can end with some material !!!! There is some pumping effect from end of cans to inside and thats why another have to shut and then U can put lamda to another. That way U can get only right measurement to analyzer.... I have played with this with some Ducati specialists with very good meters and dynos. Some analyzers are also quite slow, so if U turn potentiometer, then U have to wait some time to see right way in analyzer. Anyway Ducatis need to be adjusted to 4-5% at idle, to reach good running. It far from new cars, but luckily Ducati is not "a car". Btw, in many cars its adjusted close to 1% in idle....

Higher, than idle, the only way to get more richer, is to get new EPROM. In my mind, FIM is best, but only after readjusted with FIM software in dyno run. 91 modell (with P7) need then also FIM AMB to inside P7 to remember adjustments after turning ignition off. 92 P8 ECU dont need AMB...

If U want good performance from Ducati engine, then it need new Eprom and fineadjust it by dynorun. There are hundreds of fuel maps to Ducatis, but "all of them" are designed to JUST EXACT MODIFICATIONS, so every bike is little different=need "finetuning" to map !!!!

Hi Antti,
are you sure the 907 MY 1992 has the P8 ECU?
I'm not sure.
I have a mod chip built by a well know local dealer.
Do you think I can fit on my bike without any issue?

There is not so much difference between P7 and P8. P8 is fitted with such "memory battery", like FIM AMB is, so that P8 "remember" changes to fuel map, if its fitted with FIM Eprom and tuned with FIM software.

Normally all 92 "golden front Brembo modells" have P8, but i cant be 100% sure of it. All 91 modells, what i have seen, had P7.

I wouldnt put any Eprom to my bike, if i DONT KNOW, how that Eprom is done, i mean, what modifications had that bike, to what its was made for.

Anyway U cant have "very serious problems", if U have "little wrongly tuned Eprom", but surely its not right way, if You want everything be perfect and take all power also from better pipes and maybe better flowing air filter, maybe porting, etc.... But better change Eprom to more richer to protect exhaust valves. Not so nice to see such....

I have a '92 907 which doesn't have neither the gold Brembo calipers, nor a P8.

That eprom I have is done specifically for the 907, but I don't know much more.

Frankie, If You have black Brembos, then You have 91 modell(like i have), what can be "put to street use 92". All 92 modells have golden Brembos and lower saddle and different (original)mufflers.

I have (better I had) black Brembo calipers

, black exhausts and P7 ECU, even if my 907 was May 1992 :ugh: .

So, Yours is 91 model and its put to street 92. Simple! Registeration year is totally different, than yearmodell. There are plenty of 750 Pasos also imported first to usa, then not sold there and shipped then to Europe market and then is "old Paso",(maybe 87, or 88) and " put to street "very late", like 89,or 90,or 91.

Btw, those black 4 piston Brembos are very rare these days, so i am lucky also, cause i have black ones....
