Please don't flame me but I have noticed several posts with Cylinder Base O'Rings leaking. Attributed to heat but no one really knows.
I know that H-D sets the specs. for the blend/additives in their fluids. They test them on their engines and components and sometimes things slip through the cracks...like supposedly SYN 3 affects the rubber grommet of the stator wires exiting the engine case and causes leaks.
There are many O'Rings contained in the Twincam engine along with other types of seals.
Do you think that Competitors fluids and/or their additives could adversely affect these sealing components and cause abnormal or unusual leaks?
