Nice, kinda oldschool though...what did you do with your flywheel, have your rivets fallen out or how come there are screws in it?

Did you alter the position of the "hub" for iginition timing or what's the point of that? I've thought of that once for using a original PK XL II HP4 flywheel on a PX-did you intend that, too?

[oli-san]

wow, nice retro-tuning. hope it gives you the results, you expect. positive thinking!

What is the purpose of the dark areas on the flankes in the foreground? Balancing or hardening?

In Bella Italia ist es wohl recht üblich den Primärkorb auszuwuchten....

Das rechts gewuchtet ist sehe ich, die dunklen Stellen hingegen sehen aber nicht shr erhaben aus.

Daher die Frage, was, wofür oder woher diese Flecken kommen.

[Brosi]

Ach die. Hab irgendwie Helligkeitsprobleme mit meiner Grafikkarte. Die dunklen Flecken sehen mir schwer nach Härtung aus.

What is with the groove above the grudgeon pin?

What is with the groove above the grudgeon pin?

eine Ölbohrung - damit die schmierung besser klappt.

CIAO pozzone!!!

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

[RomeoN]

bella sir!

che tempi di aspirazione ci hai dato?

saluti romeo

Why do you use a longer durationtime for the Boostport than for the other Transferports?

[sir1234]

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.
