Ahoj, ano prepruzoval som stale ako som fukal.
OK, uz som v obraze, vdaka. Neirituje ma to, len som nechcel nieco/ servis, opravu/ zanedbat aby sa to nenavratne odpalilo a riesenim by bola uz len nova vidla.
Tu je pripadne riesenie ak som spravne pochopil

Hod sem pre istotu S/N vidlice, aby bola istota ze mas B1 verziu.. v tom pripade by ti na upgrade na C1 stacilo toto:

To co objednavate a o com dookola pisete je len fix ktory riesi dosledok problemu ktory nastal. Dosledok su nevyrovnane tlaky v komore. Problem je ze k tomu doslo a cez port urceny na vyrovnanie sa to nevie fixnut.
Vid napriklad https://enduro-mtb.com/en/lyrik-pike-yari-revelation-debonair-upgrade-2020/
Je to napisane salamunsky ale v preklade k sucknutiu u starsieho typu dochadzalo castejsie pretoze negativna komora bola vacsia a uz pri mensom rozdiely v tlakoch ak bol tlak v negativke vacsi tak vcuclo vidlicu. Kedze je tam ale ten port tak by to normalne nemalo vadit a tlaky by sa mali vyrovnat, vsakze. Z nejakeho dovodu sa to ale nedeje. Preco sa to nedeje? Lebo cez ten port nevie vyrovnat tlaky. Preco to nevie vyrovnat tie tlaky? Pretoze cez ten port nie su spojene tie dve komory.
A podla tohoto
To mozno ani nefixne tento problem ked znovu nastane. Predstav si ze ti prepusti vzduch z pozitivky do negativky a vidlicu ti to vcucne. Vyrovnavaci port je ale pristupny len v 0% sagu takze sa ti tlaky nevyrovnaju
Este by som sa asi pytal i to preco doslo k takemu rozdielu tlakov. Ak nebol zasah do pozitivky tak bud nieco uniklo z pozitivky von alebo cez tesnenia do negativky. 1500km by uz proste chcelo servis, hlavne nova vidlica chce ten servis este skor ako odporucany interval.

Why do RockShox forks tend to sag by a few millimetres?
To understand what the new upgrade does, you first need to understand the internals of the fork. Situated inside the right-hand upper tube is a notch or dimple, which is there to equalise the air pressure between the positive and negative air chambers. This dimple is positioned in such a way that the equalisation happens with the fork sagged, that is to say at approximately 25% into its travel. However, due to the increasingly large negative air chamber, the fork tends to contract by a few millimetres if the negative air chamber has a higher pressure than the positive air chamber.

How does the new DebonAir upgrade work?
Since it isn’t possible for RockShox to move the position of the equalisation notch in the upper tube, they’ve simply moved the air spring piston upwards by lengthening the shaft nut of the air spring shaft. That way, the piston and the equalisation dimple are lined up with the fork fully extended. As a result, the latest DebonAir upgrade allows the positive and negative air chambers to equalise with the fork extended instead of at 25% sag. On the one hand, this has the advantage that the fork will no longer contract, seeing as the air chambers are always able to equalise. And on the other hand, the air chambers don’t need additional equalising when putting air into the fork.

To mozno ani nefixne tento problem ked znovu nastane. Predstav si ze ti prepusti vzduch z pozitivky do negativky a vidlicu ti to vcucne. Vyrovnavaci port je ale pristupny len v 0% sagu takze sa ti tlaky nevyrovnaju
Este by som sa asi pytal i to preco doslo k takemu rozdielu tlakov. Ak nebol zasah do pozitivky tak bud nieco uniklo z pozitivky von alebo cez tesnenia do negativky. 1500km by uz proste chcelo servis, hlavne nova vidlica chce ten servis este skor ako odporucany interval.

Ved to si prave napisal a odcitoval zo zdrojov to, co vravim od zaciatku - ze B1 shaft sa zanara pod vahou bajku kvoli nevhodne navrhnutemu dizajnu zo strany RS a sice - umiestneniu eq portu + velkosti negativky.. a toto ziadne rozobratie a vycistenie portu ako si na zaciatku navrhoval nefixne.. je to vlastnost B1 shaftu.. a dovod preco vznikol nasledne C1..
