I heard it all - the riva instructions to the under the hood

don't freeze it - heat it

bake it or use a B torch or similar and uniformy heat it - or bake it at 250 for an hour - not the home range - smells.

Mine dropped out just fine - make sure you have something to catch the ring. - providing you didn't beat it in and gall it.

I had mine sitting on two uprights with the ring free to drop - took about 10 minutes top with a B torch - about 200 degress max uniformly

happy riding
