I have a Flip camera and recorded a bunch of my rides. Someone listening to the video asked if I was riding a lawnmower. He was commenting on the gear whine which is (in my opinion) noticeable. I live with it.
I get a little whine at certain speeds. Probably the most noticeable is at really slow speeds in 1st gear, like in a parking lot. Sounds more like final drive noise than transmission. Also hear some whine at around 60 mph that goes away by 70 mph.
'03 SS here and yes, it appears to be pretty normal. I've heard some refer to the bike as the "Singer" after the sewing machine. I've also been told that the noise can be altered by what kind of oil one uses, which there seems to be some truth to because, when my bro first bought his '06 Vulcan Classic 800 it didn't whine at all but, after an oil change it did have a very slight whine to it on acceleration.
I've sure never noticed it in an 07 c2. Even with quiet stock exhaust I just changed out my final drive oil with synth, but didn't notice it before either. Have you checked the level of oil in the final?
Many thanks for your helpful responses. I'm running 10w40 Havoline motorcycle oil in the crankcase, and will try Honda 10w30 to see if it makes a difference in the gear whine level. Will get back to you with the results.
I too hear a whine and i was wondering where it was coming from. i have an 08 750 c2. it is a high pitched sound,sounds like it is coming from the front of the bike. it shifts and rides fine was just wanting to know if this is what you are talking about?
revrat6, Yes, that's exactly what I'm talking about. Today I drained the Havoline 10w40 from the crankcase and refilled it with 10w40 Mobil 1 4T Synthetic Racing
oil. During a test ride there was no notable change in the level of gear whine. Evidently, the gear whine is a characteristic of 07-09 750 Spirits.
