Thinking of getting the head ported on my 270. I normally ride MX/GP on a 450 but this 270 is starting to work on me. So far stock cams and exhaust. I'm gonna order a full dr D or FMF exhaust. Was thinking hot cams but if I decide to port maybe matches cams? I don't want a fire breather that is hard to start and unreliable. Just some more overal power and enjoy the light weight of the bike.
