Re: What are the differences in the KMs??
I don't think the KM company makes KM Amer's anymore. But you never know... Bilal has more than 10 different kinds of KM's that are gonna be up. And i think all KM's hit the same if you set them up the right way. Looks are the only things that are different. And my "chinese hat" purge valve clears just as well as the older purges that my friends have.
