My 2015 Versys has a speed dependent whine (sound continues when clutch is engaged) that does not change when brakes are applied. It is present at all speeds (only audible around 20 MPH) and increases in pitch as the bike accelerates. It's pretty much impossible to tell where it is coming from, I thought it was the front wheel but now I think it's from the front sprocket.
Bike has about 8000 miles, the last ~250 of which I put on it. I do not know exactly when the sound started. Generally it's not audible above the engine, but is clearly audible when the clutch is engaged and throttle disengaged. Front sprocket is stock (rubber dampened), rear sprocket is recently replaced but did not impact sound. Chain seems to be in OK condition and stock (DID brand?). Tires are Sportec M3, properly inflated, good condition.
Things I have checked:
-Front wheel bearings (bearings seemed OK, the large spacer in between them would sort of click when rotated)
-Rear wheel bearings (bearings seemed OK, one was rotated much more freely than the other)
-Cleaned and lubricated chain (DuPont wax based)
After some research I realized I had the chain tension all wrong (I was applying moderate force to see full slack movement) and probably equated to about 20mm when measured properly. It was likely under this tension for the last 250 miles I have owned it, and I'm not sure if it started after I tightened the chain or not. After decreasing the tension, it seems to have quieted, but may be bias on my part. Used MotionPro tool to check alignment.
Any ideas what the issue could be? Could I have damaged the output shaft bearings?
I hear you, I got so fed up with the DID OEM chain, I replaced it at about 12,000 KM , my 07 I sold it at 29,000 KM with the original chain, seems they cheapened up with the 2015 chain.. Here is my post from that thread;
I just replaced my OEM chain on the 2015 to a EK SRX2 Xring chain, as the original DID chain had a tendency for the links to become tight, 12,000 KM , my opinion is it was a bad chain. Placing the new chain beside the original chain, links were identical in length for a good 3 feet , then about 1 foot of chain was stretched by about a half link. Never did like DID chain. I have both the motion pro and Profi alignment tool, both easy to use, forget the marks on the swing arm, this has been discussed a million times before, but no harm in repeating good advice.
Here is the thread, with some excellent advice;
