Vac Lines?

[Maj]

Actually its been ages since my bike had that stuff, the IAP on the back of the airbox may tee into the flapper valve plumbing, it needs to be connected and getting a good signal from all 4 throttlebodies, if there is an open vac tube left behind as you remove the other stuff plug it.
I still have to get back to you on other stuff, tried him twice but no answer... then when we were talking forgot..
