When I was doing the Build on my 81 CB750C, I ran it without signals for a long time, and to be quite honest with you, it really got to be a pita. I ride mostly a mix of half city and half back roads. I just got sick of using hand signals, while slowing down for a light and shifting, baking, etc. you get the picture. I ended up going with a set of chrome mini signals and I like it much better. However, I did prefer the slimmer look of the bike without signals, but for function, the signals worked much better for me. Its ultimately your decision, but that's just my 2 cents worth.
