The clutch cable hits the plenum whichever way it is routed. This position looks possible - i.e. for straightest line route for the main cable and square as the inner cable emerges and goes through to the pedal.
The bracket is not quite at the correct angle though, so the clutch end 'flange' doesn't sit square against it. I can't bend the bracket, but I may be able to make an offset washer to tidy this up a little.
Needs a little more playing...
The flange is 30mm outside diameter, 14mm inside. Either some pipe - which doesn't seem to come with thick enough walls, or some aluminium bar to turn/drill a hole through might be possible.
Adjusting the bracket
The bracket will actually bend - I just needed a couple of metal offcuts to prevent marking the powder coat and a large adjustable spanner to carefully change its position and let the clutch cable flange sit square against it.
Routing
I'm also offering up clutch cable, HP fuel lines & engine loom at the same time to work out the best way for them to co-exist in this area. Ideally I want to run the fuel & loom on one side of the chassis tube and clutch cable the other - the clutch cable will flex in use & this way it would avoid any chance of it rubbing/chaffing on the other services.Engine side of the round chassis tube:
Top - Engine loom
Bottom - Fuel lines
Other side of the round chassis tube:
Clutch cable
