I just got an entire kit, outstanding service and great tech support from John at carbjetkits.com. I told him that I had totally open drag pipes with conical filters attached directly to my carbs on a 1985 VT700 and that was it. From there he sent me all I needed to properly jet my bike. Let me tell you that it runs like a raped fukking date now! I HIGHLY recommend them.
If you tell them what mods you've done as well as the year, make and model he'll put a kit together for you too. It really is that simple.
Alternatively, you could waste your time asking people on here about it with less than desirable results as you continue to ride without your jets. Don't ask me how I know this
