VStrom Oil Residue on bottom surfaces; vibration at idle

Good morning all!

I've had my 2016 DL650A for a little under two years now and have encountered some oddities.

1.) The bike seems to be vibrating more than it used to. At idle/rest on sidestand, the front wheel visibly vibrates. I don't recall that happening before, but it's not excessive.

2.) The idle RPM need fluctuates and the tone rises/drops. It doesn't seem to drop below or exceed the idle specifications.

3.) A month or two back, my transmission made a huge clunk when I changed gears while going up a driveway; I came to a stop, and my transmission would click and feel like it 'stuck' and would pop at a consistent point in the chain while moving back and forth (without completing a full cycle through the chain).

3 (a): I lubricated the chain immediately after and have not had that issue since. I had used a chain wax and perhaps overapplied it? The chain had been sticky to the touch.

Most importantly: I don't see any oil leaks or any indicator of one, but it seems like there's an oil residue that accumulates on the bottom surface of the bike. I had initially noticed it around the oil drain plug, wiped it off, and haven't seen it (on that surface) since. It does seem to have coincided with that heavy 'thunk' of the transmission.

Could something have been kicked inside and damaged it?

Thanks for reading.

The first thing I'd check is the inside of the front sprocket area for wax buildup. That shouldn't cause an idle speed fluctuation though and that is not a common problem. That could take some investigating which is hard to do from afar.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014+ DL1000s. Wee = 2004-2011 DL650s. Glee = 2012+ DL650s

Understood. I've read some information about the TPS on some 'stroms needing replacement.

The oil coating on the underside weirds me out the most though, especially in addition to the relatively increased vibrations-- don't get me wrong, the bike isn't uncontrollable, but I've never noticed the mirrors visibly vibrating at rest before.

I had replaced the oil and oil filter myself, but I followed the instructions and torqued everything to spec and have used Suzuki OEM oil from the shop. I would normally think it was just road grime, but happened to brush a hand against it while inspecting it yesterday and it had the consistency of used motor oil.

If you wiped off the area and it hasn't quickly come back, then it's probably chain lubr being flung off, accumulating by front sprocket area and making its way down.

That's actually extremely encouraging and makes sense with the chain lubrication intervals I'd performed.

I've been concerned about some kind of high pressure oil spray somewhere within the body, and that jolt that I'd experienced had me worried about some kind of incidental damage.

If you have a spare week or two, reading the "chain link" (sorry) on this site will persuade you that

Turps then oil
Oil
Wax
Do nothing
Install an automatic oiler
is the answer

More to the point, do you have Givi bars? They definitely cause vibration, but usually at higher revs.
My skidplate also causes vibration.
Lastly, an old chain caused that very same 'clunk' in my last bike.
