Wanted Tech info Marzocchi Penton forks

[[email protected]]

Got to Massachusetts and the bike I bought to ride in the reunion ride (race ready) has a lot of issues.  Can someone let me know what weight fork oil and how much oil to run in marzocchi's on a 1976 Penton 250 GS6?  Luckily I brought new seals with me.

Hi,
The info I have shows for the 76 CC or MC5 with 35mm Ceriani forks are 230cc for full diassembly and 215cc for drain and refill. For the 35mm Marzocchi forks its 240cc for full disassembly and 220cc for drain and refill.
