I have kevins at HJR's mx/hardcore porting, with +4 timing and filter kit with stock carbs. currently I have PCP's on my bike and it runs well, just wondering if a set of Toomey t-5's or FMF fatty's would run just as good or better??? I know the PCP are for bottom to mid. I currently trail ride with occasional fire roads. looking for an all around pipe.. thanks in advance guys. .
