If you remove the stock front signals then you remove the running lights at the front of the bike.
If you unplug the lead wires for the tail light (and license plate light) then you don't have any running lights at the back of the bike.
IMO this is very dangerous and is also likely illegal since federal DOT requires them. The headlight up front will probably save you from a ticket or accident. Since the rear signals are not always-on running lights, are you worried about getting rear-ended?
I must be misunderstanding something!
