I bought my 2000 FXDWG last June,in a roundabout way, from a Fort Worth auction with 16,000 miles on it. Like some,I am looking for more H.P..I have no history on the bike and do not know what type of modifications have been done internally if any.Besides the obvious V&H pipes and Scr. Eag. air intake(please correct me if need be)I am interested in a Stage 1 kit for the C.V. carb. I noticed the cap has been removed on the idle/air adj. screw. can anyone tell me what would one do to make sure a Stage 1 kit has or has not already been installed ?
