No no... the boost port and the transfert duration will be the same.... at the moment it is different but i will modificate the transfert port from 120 grades to 130 grades like boostport. Ciao Romeo ancora non conosco le fasi di aspirazione della valvola e al cilindro.... perchè non ho ancora ricevuto il pacco da DRT.

Here the UPDATE! You can see the new quarry on the piston for lubrication and a new orientation of the aspiration to the top of the cilinder. The phase is 130 grades
-
CIAO pozzone!!!
-
That quarry is for lubrification!!
-
Yes it is Balancing the dark area are hardening... this treatment is ORIGINAL form PIAGGIO
-
Yes i have rivets the flywheel because i cange the big cone with the small (19) if you look good yuo see that i take a reference and i put the cone in the same position like the old one.

Don't misunderstood what i say...... I want to say that the 5 disc DRT is good and is not worst than ZIRRI! If your 5 disc doesnt work so good is your problem.......this is not LAW! Sorry at all for the Misunderstanding... i hope that VESPAOLO show me his intelligence and make DIE this disussion.

Hello GERMAN BOY! I want to present you my new motor composed by: -130 polini double admission -Mazzuchelli crank 53 mm -PHBL 24 -DRT cluth with 4 disc surflex modificated, "Kupplungsabdeckscheibe" and "innerer Kupplungskorb" -Schaltkreuz/Schaltklaue DRT -24/61 -Pk flyweel 1,6 kg (6 poles ignition et3 compatible) i'm waiting for the crank from denis because there is a delay on the delivery! Let's take this photos for the moment......i accept any kind of question! i update as soon as possible! BYE

momo you are a very nice person! I am very happy to talk with you about VESPA solution by DRT or by other. I disagree with you about all that you think....... falc has GOOD solution and products almost perfect but unbuyable! about the clutch... I have 2 vespas: The first is a PRIMAVERA 125; i put on the 130 polini DoA with 53mm crank and i will use the 4 disc SURFLEX modificated like DRT advice and this components (i dont know how to traslate CROCERA, CASTELLO MODIFICATED and DISCO BOMBATO): I will test this clutch this week (i hope this!! I have not yet received the crank from denis!!) the second is a VESPA 50 L with 130 polini more or less 20 cv in this motor I use a 4 disc SURFLEX modificated like DRT advice and i have the DISCO BOMBATO (second image) and this clutch is PERFECT!
-
hi momo denis DRT is a modest person! i think that the 5 disc is good for BIG horse power! I think it is better than the zirri clutch...... for my polini is good the 4 disc clutch do you have a falc? good choice! i want to buy a falc but it is e lot expensive! what kind of falc do you have? (sorry for the OFF topic...)
-
I'm SO happy to read your interess! Wait to next week! CIAO
-
Perfect! Next week i will close the motor so i will post a TOPIC with some fotos! byeeeeeee

This is not correct. The drt 5 disc clutch ARE NOT tested with a superpowered motor so you can't say that it isnt good for race you must TRY if you want to say this.... I use a 4 disc SURFLEX modificated with special DISC by DRT on my polini (about 20cv) and it is PERFECT! Sorry for my english..... I'm a user of et3.it I'm just finishing my POLINI 130 Double admission in with crankshaft 53. If GSF is interested to my project i will open a TOPIC on your forum. Bye
