The trinity on my uncles bike is at least 10 years old and does not have a crossover tube in it either.

As I'm sure we all know, vacuum is what pulls the fuel through the jets into the airstream to create the air/fuel mixture. Where the problem sometimes lies on the 2-1 setup is with having a single larger bore, rather than two small bores, the vacuum is diminished and has a harder time drawing the necessary fuel through to maintain a good idle speed. when you blip the throttle a little, opening the slide will allow for the motor to draw more. this can happen with a stock and a ported banshee alike, just depends all on setup. I never said every 2-1 bike will do this but it does and has happened. I've been on these forums for a long time and worked on loads of banshees, many with 2-1 setups. Not all had these issues but some did. Snop, i believe you said you had the EEK needle and this helped resolve a lot but when the 2-1s were being shipped with DEKs, the problem was more prevalent. That richer taper helps out there. I first presented this site with the EEK solution years ago and it caught on like fire and now most 2-1 setups on this site run an EEK needle, because it definitely helps. The Trinity kits seem to come with all sorts of needles, mostly DEK but I've seen 3 or 4 others for no apparent reason and the needle is a big big factor when trying to obtain proper jetting in the 2-1 setup.

Right now I run an EEL, and I am going to try and EEM. I haven't hit the wall where it starts running worse yet.
