Ducati monster 620ie loss of power..

[mr.freezer]

So guys.. before buying nwe injector I decided to try some injector cleaner.. So I put my bike back together... My injector has been 2 days in brake cleaner... when I start it up it sounds great.. i was for a test ride and it pulls like before...   .. really happy about it...  now I can    ... preventively I will use valvoline injector cleaner to fuel... thanks a lot for your help

 Yay! Congrats on a simple effective fix! Just don't use the cleaner too much!

so guys.. I am back... today I was for a ride.. when and open full throttle monster goes like a hell just to 6000 rpm... than it stops pulling and starts shooting to exhaust... spark plugs are white...

Did you change the fuel filter yet?

[mr.freezer]

of course... changed fule filter, spark plugs too..

[mr.freezer]

today gonna do TPS reset & synchro... will see the result..

[mr.freezer]

so TPS reset done... "0" was on the right place.. but throtle body was set to 1,8°.. so I set it to 2,7°.. going for a test ride... will see..

It would seem a too lean condition, from your comment "spark plugs white" . . . do you have a performance air filter? do you have performance exhaust? if so, try setting your trim around 23 . . .

For setting your TBs, did you follow this procedure, http://www.bikeboy.org/ducati2vthrottleb.html ?

Why am I asking you this? I have been there, in the same situation as you . . . long time ago

[mr.freezer]

original filter... termignoni slipons... before worked well with these.. yes.. I followed that procedure... how did you solve that situation??

Again, what is your trim setting? with OEM filter and Termis, you are "letting go" too much air and not letting enough in, but, your popping is from a lean condition, you need to check your trim setting and if you get/have access to an exhaust gas analyzer, your CO should be at or around 3.5%~4.5%; you have to check each cylinder individually and then set a 'compromise setting', that's how I solved it . .  trim set at 23 and CO@4.0%

now, how old/dirty is the air filter? do you have the 'open top' airbox?

I sent you a link to a tool, have taken a look at it? You need such a tool if you want to work on your bike yourself.

air filter is a year old looks like new.. i have original airbox... i have my own diagnostic tool... I have put termis on the beggining of season and it was good for a half of the year.. and suddenly it's going lean??? trimm set at 22.. as stock...

bring the trim to 23 . . . you can always take it back . . .
Why, because of this statement,

<snip>... to 4500 rpm it pulls normaly.. but than it lost power and start shooting to exhaust... spark plugs white..

it pulls to 4500Rpm OK and then looses power and has 'white plugs' like the one in the image?

' . . . that is lean; but, shooting through the exhaust would "tell" is too rich !!! and that it's burning "not burned AF mixture within the exhaust" . . .

now, check all exhaust pipes connections for them to be tight

[mr.freezer]

so will set it to 23 tommorow... and check the exhaust... will post the result... thanks a lot..

[mr.freezer]

exhaust connections tight.... trim set to 23...cleaned gas tank, fuel pump... checke all of the fuel hoses.. nothing helped... always loosing power and shooting to exhausts...
