I have fitted a procirciut and v force 3 to my stock 05 cr 250 2 st and am unsure where to be with the jetting, looking at the plug it looks rich when i stop the bike from flat out, but i can hear it deatonationg when hard on the gas,
i can tell the jetting isn,t right but i dont know where to be with it the jetting is stock at the moment?? :bang:
