Before I start I do not want to start a "What oil do you think is best" thread. It's been flogged to death.
Last oil change on my 05 CBR600RR I tried out the Rottella-T 15-40 dino oil. I almost imediately noticed I can now hear my valves. Anyone else experience this with this oil?
Again... please keep the "I use Brand XYZ synth with turbo boost and crank case elves" to a minimum.
