To be honest I'm more a body mods man, such as fly screen, kuryakin grips maverick seat etc., but encouraged by postings on this sight and with grateful thanks to Dinqua for his carb tuning guide and jetting table I have today removed the second baffle from my long TORS, taken out the top snorkel, put in a uni filter and rejetted accordingly (AI already removed). Took my 05 America for a run and everything seems spot on. Smooth running and nice pulling power in all rev bands, seems like a different bike. Thanks everyone
