Beta tr34 260 gearbox oil type random clutch feel.

[Creepytheclutchmaster]

Hi all found a good running tr34 picked it up yesterday the engine runs and starts very well which is a bonus but the cluch started to become abit random after about 20mins light slow rideing in tight flat Woods sometimes engaging far out (lever wise) and other times nearer the bar which is whare I like it.when I first took it out I could also seem to find a false neutral if you keep pushing down past first. But it's seems to have stopped doing it now  lol which is weard.any info would be much appreciated and does anyone know what the best gearbox oil is for these engines. I'm thinking putoline light gear but any ideas from other owners. Cheers.
