Hey fellas, I haven't been on here much since getting my 700R raptor. I know, I know, but hey at least it's a Yamaha lol! So, who or what shops are the places to hit up for an awesome stock cylinder pump gas Dune Port? I plan on freshening up the top-end so I might as well get some porting done if the cylinders are gonna be off. I'm on stock bore, what is the biggest over-bore I can go? What size cc would this put me at? Thanks.
