93 Virago xv1100 question

Have a 1993 xv1100 I am restoring/fixing up, and while preparing to remove the carburetors for a carb clean, I noticed some tiny rips in the carb-to-cylinder boots, and at least one hose (attached to air boot) torn. Below the right cylinder's air boot is what appears to be some oil.
The bike is rideable, at first it required the choke on to be able to idle, but after replacing the fuel with fresh 91 octane it now can idle without the choke. Still Doesn't run perfect, the idle can drop, it backfires quite a bit especially when letting off the gas.
I was planning on doing just a basic carb clean by soaking the jets and float bowls, hopefully that's all the carbs need. But can anyone tell me if it will need those air boot(s) replaced?

If so, would the knockoff boots on Amazon be sufficient? ($14 for both, compared to OEM $50-75 each)
At first I thought it just had some typical clogging/gumming in the jets, no intake air leaks.
Have pictures I am trying to attach of the boots/oil residue on the cylinder...

If they are cracked yes replace, I think the aftermarket is ok for those.

Ok...cannot get either of the outer bolts on the carb-to-cylinder boots to loosen. They are already a bit rounded off from previous attempts from someone else,but they are stuck in there pretty good. Tried pb blaster, grinded down a 10mm box end wrench to fit in there right, and vice grips. They are now a little more rounded off. Can anyone tell me what step I can take next on these bolts? Even if it involves cutting thru the boots to get the carburetors out, the boots need to be replaced anyways.
Maybe some kind of dremel can fit in there and grind the bolt heads off?
I originally thought I could get the float bowls off with the carbs in the bike and try to remove the jets, ended up taking too much time to try it. Has anyone done this or know if it's possible?

Well you are just going to have to do whatever you have to to get them out. I would try to cut the boots off to get a better grip on the bolts. Put the vice grips on as tight as possible. Also try heat with a torch, that helps too.
