Hi all
Had the pleasure of my clutch packing up, nothing at the lever ,managed to get a friend with a car trailer to get me home Mine has the TTS hydraulic conversion and this is what i found on dismantling ,O rings shot and damage marks on the Oberon slave ,
Phoned Oberon ordered a new unit that comes with silicon 70 o rings ,the dome on the the TTS part does not match the Oberon part to well so will modify or get a Buell part.
Read thro some old posts and not so old ones and i should have seen this coming

Re the dome or bullnose nut, the TTS one does indeed have trouble seating into the slave cylinder ok, I ordered the Buell one and it fits perfect (the slave is made for a Buell) but the bore and thread are a size down from the TTS pullrod so you can't use it without modifying either the pullrod or the bullnose nut.
