Revitalize rubber?

[pentons4ever]

I have a 1997 le jackpiner..the rubber boots part of the air box keeps cracking,I've replaced it twice this year with nos ones.does anyone know if their is something I can do to help the rubber not crack within 3 or 4 rides.

The stock one lasted 15 yrs..the rubber seemed pliable..super bummed planned on racing this bike with my son this year

When you first get them, apply a liberal amount of Armour All or similar product, and reapply frequently, both inside and out side. You might be surprised at how soaking them in plain warm water will help them retain moisture. What have you got to loose??  Simple cracks can be sealed up with silicone. There is that new miracle stuff called Flex Seal that you see on TV that may be helpful.

I will do that on the one I will be putting on..I also thought of motor mounts being loose..but didn't find anything loose.i do soak the old penton air boots that r rock hard to use on a bike that's just gonna sit.i also thought the subframe might b the culprit but nothing loose there.

Silicone spray, inside & out, rub it in. Coat it 2-3 times.

I  have had good results with Mothers Back to Black trim & plastic restorer . Works great on old tires. At any Auto. Supply.[]
