I have called Jeff at fast,Rob at RDZ,And Nate McCoy.Jeff phone was disconected so I didnt get to talk to him,Rob just told me hell call me back and never did.But Nate spend about an hour explaining to me my different options with my budget And my weight.He taught me alot over the phone even tho he may not know it lol.SO hes going to be the one building my motor.I also sent rob a message through ebay about some pipes and he never responded.So I guess he doesnt realy need customers that bad
