Any speed/hot rod shops around? Found Red Line Shockproof Heavy at one of those. Be ready for the "tomato soup" appearance if that is your choice.
Experience from one guy, one bike, one transmission: factory oil, the rest all 75W-140 syn. Royal Purple, Mobil syn, Amsoil syn- no noticeable difference in finding neutral or clank into gear or shifting.
Spectro 6 speed and Redline SPH much improved over the above. Will be continuing with Redline as it is easier to obtain locally and not quite as expensive as Spectro. 2008 Road King.
