Hi guys!
As I've told you.... actually, training it's in progress......
.... and I've done about 700 km....
BUT.... I've tried to push engine over 8000 rpm.....
... N O T H I N G! I mean nothing!
Carburetor setting? I'm thinking at carburetor, just because I've put into an heavier fuel floater (9 gr.)....
..... instead of the original fuel floater (6,5 gr.)....

Well Now I've an original 6,5 gr fuel floater! I took it from an original carburetor Dell''Orto PHBH 28 MD!!!

Here my "old" and very dirty 6,5 gr fuel floater, and a "new" (used) fuel floater in good conditions!


My "old" and very dirty 6,5 gr fuel floater


See you on next episode!

Hi guys!

Well..... Ready to search engine problem: Why my engine stop at about 7500/8000 rpm?
Maximum power it's at 9500 rpm!!!


Leave lateral fairings.....
.... here we are!
Chance 1)
I'm leaving out a 9 gr fuel floater and setting an original 6,5 gr into my Dell'Orto carburetor PHBH 28 MD

- 1st Unscrew metal fix bands of carburetor




- 2nd Unscrew the carburetor bottom external screw (14 mm) for leave out maximum jet


- 3rd Maximum jet in my hands! (Dell'Orto nr. 155 = 0,155 mm).


Now I can leave out bottom basin of carburetor.
Here I can change fuel floater: leaving out a 9 gr fuel floater and setting an original 6,5 gr .

See you next episode!

Hi guys!

Searching engine problem: Why my engine dosn't run over 7500/8000 rpm?

Chance 2)

Maybe too much oil in air filter?


No! Just a little oil leak from air filter..... Uff!


Result?
.....
.....
Uhm.... nothing!
Again... and again.....my engine, doesn't run over 7500/8000 rpm in 6th gear.....

Ok Joachim..... we got a problem!!!!!
I think that you have reason.... maybe it's APTS valve!
Damn!!!!!

See you next episode!

only in 6th gear?
Maybe i have not read this before
Did you use an original chain wheel and sprocket?

ciao Joachim

Hi Joachim!
No...... I mean....
.... about 8000 rpm in 6th gear,
.... about 8300 rpm in 5th gear.....
.... and so.... until at 2th gear where I reach about 9000 rpm....
Lacks power!
About chainweel and sprocket, are in original dimensions and teeth.....
Not enough power..... I think that you have reason about APTS valve.
I'll try to take apart it next weeks...... My God!

Ciao

Marco

[Joachim]

as said before. I can hear and feel when the valve is opening.
Maybe it did not open completly.

Uhm.....
Yes...
I agree, you have reason.....
I must to take my workshop manual and read it very carefully....
And..... after that re-open engine.....
Uff!!!!!

Thanks a lot!

Ciao

[Joachim]

you may better start with the 'easy' things

Your engine has the metall cover over the valve, right?
Did the system work without the cover?
So you may take it away and rev the engine up to see what happens.
Sorry, but i did not know how thw pneumatic system works

Good luck, Joachim <leaking water pump and engine case>

Ciao Marco,
vedo che la tua bella è sempre più perfetta!

Io ho appena portato a casa la mia...e tra poco si inizia il restauro più conservativo possibile...

volevo chiederti un paio di cose:
ho notato che il cavalletto mi ha inciso con la parte finale il forcello posteriore...anche alla tua era successo questo? come posso ripristinarlo?
il parafango anteriore è tutto scolorito, come lo rinnovo? riverniciato non sarebbe originale...tu ne hai uno per caso?
devo rifoderare la sella... colore esatto quale sarà? non è che per caso hai già la scritta GILERA su file in modo da farmela stampare per poi riprodurla sulla sella?
il codice colore del serbatoio sai qual è o magari se hai già un serbatoio?
Per i pezzi con relativo costo mandami pure un mp,

ciao e grazie mille...

[gileraXR1]
