I've redone the wires on my R65.
I used a silicone isolated wire which is wonderful because very very supple. Caps are NGK with a 5K resistor in them. Good waterproofing ! And easy to install. I found screwing "plugs" to fit at the other end in the ignition coil. Fine also.
I put a dab of vaseline into the coils hole to prevent moisture going in. Et voilą !
