RR,
In answer to your questions,
1. The standard clips can be used if the carbon airtubes have the little lugs in them. You have to do up the clips by removing the tank and doing them from inside the airbox.
2. JHPs undertank filters are made by Pipercross, good stuff! The tank comes off by undoing the single bolt at the back of the tank. It's easier to get at if you take the seat unit off first. As has been mentioned above, lift the tank a minimal amount first and reach under and undo all the fuel, breather and electrical conections before you remove the tank from the bike. The front end is held in place by a locating pin on the front underside of the tank which slips into a receptical at the front of the airbox.
3. What micro switch???
Cheers, Neil.
