Tech note on black nitride valves - Black nitride is a hardening treatment that increases the surface hardness of the valve yet it keeps good ductility beneath the hard nitrided layer, unlike stainless valves which are more brittle throughout. A black nitride surface finish is also smoother than chromed valve stems resulting in less friction between the valve stem and the guide which reduces galling. It also makes the valve last longer with lead-free fuels and fuels that contain alcohol. The black nitrided layer is adhered to a valve's base material at a microscopic level, so it can not flake or brake off. The black nitride coating is applied to the whole valve while traditional chrome coating is only applied to the stem. 1979 - 1980 Harley-Davidson1200 Fat Bob - FXEF1977 - 1979Harley-Davidson1200 Low Rider - FXS1971 - 1978Harley-Davidson1200 Super Glide - FX1973 - 1980Harley-Davidson1200 Super Glide - FXE1978 - 1984Harley-Davidson80 Electra Glide - FLH1981Harley-Davidson80 Electra Glide Heritage - FLH1979 - 1981Harley-Davidson80 Fat Bob - FXEF1979 - 1982Harley-Davidson80 Low Rider - FXS1983 - 1984Harley-Davidson80 Low Rider - FXSB1980 - 1982Harley-Davidson80 Sturgis - FXB1979 - 1984Harley-Davidson80 Super Glide - FXE1980 - 1984Harley-Davidson80 Wide Glide - FXWG1983Harley-DavidsonDisc Glide - FXDG1966 - 1980Harley-DavidsonElectra Glide - FL1966 - 1984Harley-DavidsonElectra Glide - FLH1977Harley-DavidsonElectra Glide - FLHS1980 - 1981Harley-DavidsonElectra Glide - FLHS1983Harley-DavidsonElectra Glide - FLHT1977 - 1981Harley-DavidsonElectra Glide Classic - FLH 12001979 - 1984Harley-DavidsonElectra Glide Classic - FLH 801983Harley-DavidsonElectra Glide Classic - FLHTC1984Harley-DavidsonElectra Glide Special - FLHX1982 - 1984Harley-DavidsonElectra Glide Sport - FLHS1983Harley-DavidsonSport Glide - FXRT1982 - 1983Harley-DavidsonSuper Glide II - FXR1982 - 1983Harley-DavidsonSuper Glide II - FXRS1980 - 1983Harley-DavidsonTour Glide - FLT1980 - 1983Harley-DavidsonTour Glide Classic - FLTC
