When Iím driving the engine sounds as if itís pulsing. Thatís the best I can describe it. I donít notice any power loss any thoughts.

Learn how to better describe the "pulsing"?

Seriously, at what rpm, and at what frequency is the "pulsing" occurring?

The v-twin does produce a nice rythmic thrum.

If you have two things making noise at two regular frequencies, you will magically get a "beat frequency" that is the difference of the two.

So if you had a 5000 Hz tone (like a beep) and a 6000 Hz tone (like a beep, but higher pitched), you will *also* get another 1000 Hz tone (which is a fairly low tone).

That can throw people off. I can take two high pitched noises, and make a low pitch noise out of it.

Everytime I ride my XB into the parkade of my high-rise condo I get a pulsing resonance that threatens to deafen me. It's my helmet reacting to the exhaust!
