Better just to get new ones. Over time, the boots shrink and become stiff, making it difficult to remove and install the carbs. It also may be the cause of airleaks if they are not sealing well.

Here's a pic of old boots vs. new..I think the difference is apparent.

+ 1, Some of the boots also have a slight offset so try to note the position of the old ones when you take them out and the new flexible boots will go right on.

i have a similar problem with my boots. they've shrunk and when i get them on the carbs, the top bracket won't reach the frame to bolt up. if i move the airbox to align with the mounting holes, the boots pop off the carbs. until i have the dough for new boots, i got the boots on the carbs, clamped them down and shoved styrofoam between the back of the box and the frame to hold it secure. temp fix only, for sure

New boots definitely make it easier to install. I am not sure if this applies to your bike but my 850 boots have to be indexed correctly.

When you get the new boots, make sure the little tiny dots on the boot line up with the tiny dots on the airbox. I didn't even notice they were there. That and a little lube makes the difference in getting them to attach to the carbs

Yea, removing and installing the carb-rack can be a wrestling match for sure.
It took me a while to get them in and out of the bike, there's very little room.
I really had to go at it pretty good, leveraging my body on the side or on-top of the bike for maximum pulling power.
There's very little room, however loosening the airbox up and moving it back an Inch or 2 can really make a difference.

I just took mine out, today. Two screws and one hose to remove and the airbox came out. After that thing is out of the way, the carbs came out easily. I used a little silcone spray on both ends of the carbs to help lube the rubbers before I removed the carbs. My rubbers are all good (best kind to have) so they are flexible enough to move things around.
