I somehow lost my atac valve for my 1984 cr80. Not sure how some I haven't touched it and everything is right where I left it except that. Must've grew legs and walked away and I'm pretty pissed right now. Anyways... Would it be better to just delete the atac valve all together? It's impossible to find one and I heard it performs better without it. Is that true? And how would I go about deleting it if so?
