I bought a 2007 K9 with 2400 miles. First thing I do when I get it in, drop the fluids and replace them. Last K9 I had did the same thing and went Amsoil in the engine, Redline Synthetic in the primary and tranny. Worked great. Did the same on this bike. Syn in primary did not work out well. Took the outter primary cover off, pulled the clutch pack apart and cleaned it up and let it air out for a few days and refilled with RevTech primary fluid.....works like a champ. Guess this pup isn't the synthetic type...
