OK after seeing the thing for real it was definitely not the Right gasket

[ducatigirl100]

SO Ive open up the thing and cleand it whit compress air . I've inspected the ole thing and I think I've found the solution to my problem ! 

The pilot screw is all bent at the end !




Now i'm just tring to find the number of the part so I can find it on the net

Tanks for the link although there out of rebuilt kit but I'll check latter

If you can get the parts then why not overhaul your carbs.

You may get away with the existing gaskets if they dont leak. You may get away with carefully straightening your idle mixture screw needles, but if your bike has done 10,000 kms on the stock needle jets, you will most likely need to change them.

the bike as 48 000km and I drove at lest 10 000 km whit it ......so I guess it time to shop at monsterparts  dynojet kit just ordered !   I'll post a photo of the needle jets tomorrow

Have you checked the carb diaphragms?  I had lag on opening the throttle, and I had cracked carb diaphragms.  Inspect those if they are cracked, I found a replacement from a Suzuki for $30 or so per diaphgram.  Beats the $100+ per slide/diaphragm Ducati wants.

Diaphragm where inspected  and there OK

Today, I've adjusted the hight of the floats to 14mm because one was at 17mm ans the other one at 14 mm.  the motor is more responsive now but after inspecting the needles jets I found that the where use to the point there was some discoloration on them :



Dynojet kit is ordered 

appart from that the exhaust is now 'popping' like crazy !  maybe the pilot screw's "to rich or to lean " perhaps ?

[ducfun]

Ca-cycleworks has a tool that has several different size wires for cleaning jets. I found it useful when cleaning mine.

For what it is worth, if you find yourself dumping cash into cleaning your stock carbs, the FCRs are worth the cash.

[wannabfast]

if its popping, you are probably too rich, turn the pilot screws in 1/4 turn

Needle jet (emulsion tube):

They tend to wear oval

Dynojet kits don't come with them.  Your dealer might stock them.

+1 . Thanks Howie.
Sorry 100. Probably my Australian "English" causing the confusion

From the picture the needle jet is the tube the needle goes into.
The needle jet or emulsion tube will wear in a way that makes the bike run too rich and foul plugs. It can cause rough, lumpy low speed running and will effect fuel consumption.

Good work on setting the float level.
The Dynojet kit will improve performance. You planning to run an open airbox with K&N filter or keep the airbox stock?

It's turn its better now almost no "popping"     I just learn something today, tanks
