Soon after taking possession of my US origin 1200 2V, I performed a canesterectomy and cleaned up the associated piping, as suggested on other forums.
Yesterday I rediscovered that the vacuum/balance ports on the throttle bodies are connected to each other with an open bit of plumbing that has a central T piece that used to head off to the can under the seat. I blocked it off down that end as per, but never considered that this joins the throttle bodies together and have never given it a second thought.
Until I was connecting up my new CarbTune...
What is the collective opinion... should I remove this bit of tube... does it benefit or detract?
Obviously, I need to go for a blat, then remove the pipe and repeat, to see if there is a difference, but opportunity is not currently leaning my way.
