AIS delete question... remove 2 hoses to air intake nipples?

[InfinitySurf]

Question on my 2012 RSV. Just finished doing valve check (all within spec), replacing the valve cover gaskets and the gaskets in the twinkie.... as I am putting this back together I am wondering if I can DELETE the 2 hoses that connect to the front left and the rear right intake boot nipples since I previously plugged/deleted the AIS system in 2021? Dont see any reason why I cannot just remove those 2 hoses and install nipples to close them off like the other 2 cylinders but would like to verify since I saw a post a while back where someone says something about one of those hoses (maybe to the front left cylinder?) connecting to the cruise control so if plugged then the cruise will not work? I rarely use the cruise but would want to keep that option altho I cant see how that hose would make a difference to the cruise with the AIS system already plugged up. Can anyone confirm? Few pictures attached.

Appreciate it!

After I deleted my AIS I removed the hoses and capped the intake ports. No problem.

Thank you for the confirmation!

I think i linked mine front to rear on each side of the engine.  There was an article on one of the tech forms about "balancing" the engine pulses to the carbs, but I've read on other forums debunking any improvements and never really worried about it since on the Venture.  I'm digging into my carbs this winter so maybe I'll eliminate the cross-over hoses.

I read that thread here and saw linking them mentioned in a couple other places, the comments about the idle being wonky after doing that kept me from going that route. I just finished my list of maintenance items on the RSV for this winter and have my bike back together with everything running perfectly again, so planning to sync the carbs on the next day where I have decent weather. Figured after doing that I would go ahead and cap the other 2 nipples. Guess I also need to remove those 2 hoses and cap them where they terminate into the AIS system. The rear hose will be pretty easy to access but that front hose looks like its gonna be a PITA to get too since it terminates between the radiation and the bottom front of the engine. I may end up just plugging that front hose for now so I can get all 4 nipples capped.

1/2" Copper plumbing caps were a snug fit with the factory stainless webbing "gaskets" for the AIS ports on the heads.  10 yrs later and they're still there.
