Question Return of the Carbs

I took out carbs little to no problems, cleaned it and attempted to reinstall. Turns out my airbox rubber ducts are basically hard as rocks-thats the fate of old rubber- and virtually impossible to reinstall to the carb. Tried boiling them, it worked for a sec then popped out. expletives were used.
Open to suggestions, but may buy new oem ones that are more malleable than my boulders.

AirPods are a very good option that many people have used.

I was able to make my original boots work by doing the air box/battery box separation mod. Before that, the assembly kept pulling the carbs back off the boots every time I put them on.

Fairly certain there's a solution you can soak these in to soften them up easier.

Yes there IS way to restore oils back into rubber that have evaporated over time. You’ll need:

- bottle isopropyl alcohol +90%
- small 4oz bottle Oil of Wintergreen (methyl salicylate)
- small bottle glycerin
- some empty glass jars (peanut butter, jam, etc)

Pour into glass jar:

1-part Oil of Wintergreen
1-part glycerin
3-parts alcohol

Stir well and drop in your rock-hard rubber part so it’s completely submerged. Screw jar lid on and let sit for 1-4 days depending upon hardness. Shake jar regularly if you see separation. Remove rubber and wipe off excess fluid. That’s it! Soft pliable rubber just like new!!!

Note: use nitrile gloves to handle. Large doses of methyl salycilate can be poisonous.

Danno's solution is probably more effective than mine, but I've used that cheapo silicone spray lube stuff that comes in an aerosol can with great success. Just put the parts in a Ziploc bag, blast it with the silicone stuff, enough to cover it, and soak it for maybe a weekend, maybe a week.

I'd also like to add that there are implications to using pod filters. It's a big long-standing, often not-so-civil debate about whether or not to use them. You can use the search function if you'd like to see all the moving parts of this discussion. I ride in the rain a lot, so that's reason enough for me to keep my airbox.
