What I also meant about the BMW's in Europe is that they sell a gazillion of them over there so it's likely a pretty justifiable business on it's own; what they sell here pales by comparison.
You are right about the cam adjusters.........didn't know about the S&S ones, so that's a good tip (S&S is a big customer for us too). I thought the general design life of the H-D ones was supposed to be around 25-30K?, so 35-40 would surely be pushing it.
You are also 100% right about the Amsoil & temps..........same is true for Mobil 1 V-Twin. Harley Syn3 is pure schitt, not full synthetic either & I would not run it in my bikes unless it was all that was available.
