Picked this up fro go-karters who use this on their tires to make them stickier/softer...

Wintergreen oil mixed with acetone.

I used this to restore the dampeners for the engine on my Yamaha RD400 engine and also the intake manifolds.

What was hard became soft.

You will want to do this in a well vented area as the smell is quite strong.

In the case of the dampeners, I soaked them overnight and they really swelled up and looked mutated.  After they dried out they looked normal.

For the intake manifolds, I kept using a rag to wipe the combination of fluids on about 15 or 30 times as I was working and they became soft again.

I'll be using this on the throttle body boots when I tear down, assuming that they aren't cracked.

Definitely wouldn't try saving tires this way though!

What's the ratio of oil to acetone?

I actually used Xylene and ~25% oil of wintergreen.

A lot of people say to just use diesel fuel (less expensive than oil of wg and xylene), but there seems to be more distortion...
