I just bought a 97 RN superjet with protec head, factory b pipe, dual 44, And he said something about ported but I'm not sure what he means by that! Anyway I thought I would be more powerful , I mean at the beginning it was now its loosing it. It has no intake grate he said he didn't need one, i opened the case to make pictures do you guys could help me fix the problem. I also think its not carbureted well maybe you guys could help me there too! Cause I'm thinking about putting two 38, cause I'm reading it would give me more bottom. Any advise is welcome!! Here are some pics
