The 912 Operators Manual states that normal oil pressure at 3500 rpm or higher is between 2.0 - 5.0 Bar (29-73 psi). Our 912UL with over 500 hours on it is running around 49psi at normal cruise rpm with the engine at normal operating temperature. After adding the shim, if you are getting 66 psi during cruise and a warm engine, what is the initial oil pressure when starting and the engine is cold? Does it get above 73psi? -------- Thom in Buffalo N221FA Allegro 2000 912UL N197BG FS1/447 -------------------- "Blind respect for authority is the greatest enemy of truth."

My FDCT started at around 55 when new and now at 160 hrs. it was running at 46. I know this is well within normal range, but I would prefer that it was a little higher. I believe it does a better job of forcing oil into tight areas under heavy use times, but I have no documentation to back that up. A lot of cars and motorcycles run around the 60 psi range. When I start my engine and idle at 1800-2000 rpm my pressure is about 65 and even when I am at cruise it seems to stay there. My oil pressure never gets above 66 psi. I use Amsoil 20-50 motorcycle oil. Less foaming characteristics and better shear qualities than Mobile 1 Racing 4XT. Moblie 1 is a good oil I just prefer Amsoil for my gear wear. Have been using it, as a lot of other riders, in my Honda Goldwing for years. My tranny in my Goldwing is absolutely smoother and quieter. -------- Roger Lee Tucson, Az.
