Identify this aftermarket Hydraulic Clutch fitted to my Beta Zero ? 

Any guidance here appreciated 

I know literally nothing about 1990 vintage Trials Bikes 

I purchased what I believe to be a 1992 Beta Zero 

But it has this Hydraulic Clutch set up ? 

I have a number of questions like how do you bleed it ? It does not seem to have a bleed valve but I am sure I can research that if I first know what it is. 

I am sure this bike came with a Cable Clutch

Wow never seen that before! You can put the bleed nipple / banjo bolt from an Evo on to bleed. Th nipple may interfere with the exhaust. It would be interesting to see the inner workings of this. Thanks for sharing this .

Ok I found the answer to this 

Apparently its a Dougie Lampkin Works Special.. 

Thank you 

Surely Dougie was still riding schoolboy trials  when the 92 Zero was out so doubtful it was a works special for him.

Someone that seems to know the history here said the first prototype he saw was when he was 16, I assume that means his father helped ? 

I have no idea.. they are very confident its out of the Lampkin Engineering shop

Regarding bleeding technique…

Maybe it’s like the Scorpa Easy, where you just crack the bolt and bleed down the face of the clutch cover.

 

If you fit a bleed bolt, agreed it might foul on the exhaust.
