160 CC?
I have a mystery Charlyn valve that is less than 160cc. I know this because I replaced it with a 160 in the last buggy and my steering sped up. I would trade it if you are interested but I have no way of knowing how many CC's it is. I even called Charlyn direct and they could not make sense of any of the markings. I bought it from Sean at POS long ago and when he shipped orbitals out he shipped them without their ID tags. If I had to guess I would guess it was around 100 - 120cc.
