Years ago I owned a Honda CX500E which had perished inlet rubbers. They were bonded to the aluminium flanges. I didn't fancy paying Mr Honda £65 each so I repaired them. I purchased a mountain bike inner tube for around £3 and cut lengths the same size as the rubbers and I stretched them over them. Being paranoid I stretched another one over the first. The bike ran spot on for the remaining two years that I owned it. You also have the remaining inner tube should you need to make another repair. If you cut them neatly they are difficult to spot too. If you're extra paranoid you can glue both ends down with evostick adhesive but I didn't bother. Hope this helps.
Never underestimate the ingenuity of an idiot!
