Yeah it's pretty tight in there. My shitty white wire slipped and rubbed through on my flywheel a bit and was shorting. I put a bunch of hondabond on the wire and heatshrunk it. So far so good.
I am going to grab one of these. open the holes in and trim off the tall spots and stuff. I think it will fit. That will give me a separate source for brake juice and i'll swap to 12V and run a regulator for the head/tail lights.
I feel like i might as well get the cdi -___-
