All... since saturday I've noticed a steady whining sound when I'm leaning into curves. The sound modulates higher/lower in pitch based on speed and disappears when straightening up. Noise is present leaning to either side and isn't noticable until riding for a while. It appears to be coming from beneath or behind me, but it's tough to tell.

I'd check your front and back wheels to see if there's any extra play. If it only happens when leaning the bike over, it may be related to the wheels somehow.

I don't know, but could it be a low oil situation, or oil not circulating? Like if something is uncovered that is usually wet with oil?

Give the man a cigar. Likely culprit here is the tires.

Oddly , some tires only seem noisey in turns. I remember running some Dunlap K-81's on my RD400 that almost howled when leaned way over.


Also keep in mind when you are "leaned over" your ear is able to pick up noises that are reflected off the road alot easier.

My only real suggestion here is to check your tire pressure and then not worry about it.

msh1156 you have owned the Vulcan for about 16 months. Is this still the first set of tires you are running? The thought occurs to me that if the tires are getting close to being worn out, the tread in the center will be the most worn, and better/deeper sipes on the chicken strips may howl or whine more when leaned over.

Mine did that when they were ready for replacing, Tire is the problem.
Get a set of Metzlers and you wont be sorry.
Also look into upgrading to 110 front instead of the 100 it has stock.

Sounds like tires are the problem (or at least the cause of the noise) if they are still good treadwise and not badly cracked, I'd go ahead and wear them out before replacing them. The whine wouldn't bother me at all, as long as I knew what it was.


A few other remote possibilities. Check the final drive oil, if you haven't done the splines, definitely do that before riding it again, also check swing arm play and clearance. The swing arm has to be an exact distance between the pivot and frame, or the drive shaft will not line up properly. If it is loose, it might be moving when you lean over.

Are you sure it isn't the pegs dragging? The Vulcan will lean waaaay over for a cruiser, but the pegs will drag eventually. Jerry.

Thanks fellas.

Tires (Kenda Kruz) are new as of last fall... no noises until just last weekend. Will confirm pressures again. (110 in front already)
Splines lubed last summer - a few thousand miles ago. (with Fergy's help)
Gear oil changed with engine oil, 500 miles ago. Both get changed 3k miles. Oil levels perfect.
Will check swingarm too.

Here is an observation. My modular helmet makes so much noise in the wind that I never get to analyze noises like that. I took it out bare-headed yesteday and heard all sorts of worrisome noises. Now I need to find an experienced Vulcan rider to ride it and reassure me that everyting is okay.

I know you have a whine. One thing i noticed on my bike was a howl....i attributed it to the wind coming over the ports on my stebel air horn. I do check my air pressure prior to launch constantly.
