Engine Oil Viscosity for 2014 Models

[xNE0x_imp]

If you are not aware, these are air cooled motors. They make noises, and can't hide them like a liquid cooled motor. Why? Because there is no sound damping. Liquid cooled motors have water jackets that mask a lot of these noises. I would like to point out, that this CB1100 has so many moving parts. Way more than it's 70's predecessor. It's not uncommon for an air cooled motor to make noises. Some more distinct than others. Unless you start seeing metal shavings in an abundance in your motor oil, I would NOT worry about it. But, if you want to take it to a dealer and have them tell you different, by all means do so for peace of mind. Based on my personal research, and no evidence of a catastrophic failure, and an email posted by another poster from Honda... I believe this noise to be normal operation.

Now that we've gotten that out of the way, if I had to take an educated guess it's something to do with the cam chain tentioner.

Honestly, I feel like so many people are LOOKING for an issue on this bike. Just RIDE it, and take some Ritalin for that A.D.D. before your ride.
