Luis if you buy these pictures from IWM in high resolution, you can see the route and special bowden cable clips on the headstock.
I've realised since I built my W/NG that I've put the top links on the wrong way round. The chamfer should be on the inside to stop the cables chafing. If it wasn't for the side check springs, I would have changed them round by now!!
Months ago I tried to buy those pictures and I did not have the answer. If I travel to the UK after the DDay I will visit the IWM.
My current Carb is at 89B and maybe its height is what causes the cables to bend at the bottom of the tank.
I will travel with 3 friends in a motorhome from spain.
I have consulted that campsite and it has no places.
We have booked near pegasus bridge.
