Ok I use rock oil comp 2 for my mx bikes is this ok or should I use somthing more aimed at trials bikes. Well iv got air filter oil and cleaner so that's no trouble for me . Yha plating is 120 from Lancort and a good piston I gues is 80 to 90 quid . I'm a mechanic just need the specs and tolerances and im ok . Looking at the pics of the bike the oil is brown so I think its ok but u never know . If the casing has gone how much is a new one . Yha linkages need top services and fresh greas every 3 months I do mine .Ok so there isn't any travel lost with the rear shock set up . Chears ian
