My Superhawk makes a "whining" sound
Hello. My Superhawk makes a whining sound. The sound seems to be coming from the engine area. Any info would be greatly appreciated. My bike has sounded like this for a year, and if there is something I can do, I would like to do it. Thanks

mine makes this noise as well and has for as long as i've had it (from 8000-13000 mi). somebody on here once suggested that it sounded like a Jetson's mobile and i think that's pretty accurate. to me it seems normal. i've got stock CCTs.

Mine also. Bought bike last April 06 had 6000 miles on it, now has 15000 on it. Made the sound from the day I got it. I just assumed it was the water pump impeller, or just a characteristic of the engine. I heard a TL got by my shop the other day, and it made the same sound only LOUDER. May have been due to stck pipes on the TL.. I cant hear dick over my pipes... (shortened Erions by half)

I think we've established that this is a normal sound. the explanation I got from a guy at my local shop was that all V-twins with overhead cams make the noise to some degree. its the price we pay for not having to adjust the valves until the 18,000mile mark. ducs are gear actuated, so they don't whine, but they need more frequent maintenance. pushrods, same thing, but overhead cam engines can rev way higher than pushrod(harley). just gotta learn to live with it. RC51, TL1000, KTM superduke, they all whine.

well I guess I stand corrected. are the 4 valvers set up different? I could have sworn that I heard ducati's have gear actuated valves.

The old bevel drive Ducks had them. I think they're all belt driven now.

I was a bit confused in the beiginning whan I saw this drawing as it use a return rocker arm spring but it's not used to actually lift the valve, but only to apply a light pressure when closed. Therefore a much lighter spring than on conventional DOHC machines.
