anyone linked their intakes with fuel pipe? as seen on another site

[ghostbiker]

I did the crossover mod with T's and later changed to just pipes.
Initially I noticed a slightly smoother tickover, this didn't change when I went to just pipes.
Since then I have had other mods like ivans and ignition advancer and ais removed. I did go back to the OE way last year and didn't notice a diff.... Maybe it helps unmodded bikes maybe it helps any or maybe its in the mind.
