Hey mate.... it isnt a easy or hard to setup hydrolic clutch up, more of a headache
But there are various ways you can you a Urvan internal setup, or inbay setup.
I used a inbay setup with a new 180b clutch clyinder. I put mine next to my brake masters because the wall there is extra stong and doesnt flex and then i could use my stock clutch. I cut a hole there (which is quite tight measure twice

) then i had to mod the linkage so it was alot shorter, then lined up straight with my pedal and drilled the hole.
Other options are the under dash (Urvan internal) and using a s1/s2 bluey pedal mounted left of ur old pedal with the clutch master setup.
I have pics of my setup i will post on 1200.com and put a link no here for ya
