gasket,
I have standard bars, standard cables & wires with Rivco risers, and rerouted all wires/cables behind the upper triple tree and cut/removed the looms in front.
If you need to disconnect the throttle cable for any reason, other than bellcrank adjustment, do it at the throttle grip housing. In fact, to swap bars out you may want to do that for ease of swap out. Be sure and put padding on the tank and secure your gauges out of the way when doing the "operation".
For original routing or removal of throttle cables from housing, see the shop manual. The online one is sufficient.
Have fun
