Would it reduce turbulance quicker resulting in a greater enhancement of flow? Or would we get a reduction in air flow, kind of counter productive? Deminishing returns?
I noticed that a sharpy pen body has such a taper, very slight but there. I can get a whole bunch for a dollar in the flea market, Humm. Man this thread is cooler than color tv.

I don't know if that would work better. My first thought is that it would indeed accelerate the outflow more but I think once the air got to any open space, such as tube area or the mouth of the carb, it would creat more turbulence at that open spot that straight straws. But who knows. Maybe could try it with my tester tube setup, add some smoke and observe for turbulence. If I do that I'll take video of it for all to see. If that concept does work, I do think that tubes of a small diameter than sharpies would work better. But then again maybe not. Each time I try something I learn something new either because of the results or because it makes me research something specific about it, or both.
I do know one thing for sure. I spent a good bit of time today on a 2008 Honda VTX 1800 and a 2007 Yamaha V-Star 1100. I rode a good bit of very curvy back roads and some highway riding on both. It made me realize just how fast my bike is, grin factor and all. Those were nice bikes, but I was sure glad to get back on my bike. Sure, it ain't a sportsbike and I don't need a sportsbike squid chiming in about power and speed. I've had I think a dozen maybe a few more bikes of all styles and I know exactly what speed and power is. But when I twist the throttle on my bike, I get torque, speed and total grin. The grin factor is 3x what is was on those other two bikes. I've got a much higher appreciation for the thumper now. Around town and with the mods, it's probably the best fun/comfort bike I've had.
The owners rode mine as well. I think their goal was to make me envious of their bigger, loaded, high $$$ bikes. I think they wonder how I could like riding my bike compared to all those other head-turner bikes that can be had with some creative financing and a little financial sacrifice. It was pretty obvious their plan backfired. I've seen few men grin in amazement as much as those two did after riding mine. I'm guilty of that mindset in the past. I understand where they are coming from. I'm glad I got past that stage. Enough said.
