Bizarre Vibration

Hello All,
New guy here. New to Vstroms and forums.
I bought an 05 DL1000 last week. This fabulous machine just turned 30k today. I have a question about a vibration at 2k-3k rpm on acceleration in 1st. There appears to be a resonant vibration that feels/sounds like all the plastic is stuttering at once.
Can this be normal?
Any insights would be helpful.
Thanks

Sounds like it may be clutch "chudder"
Do a search on it you will find lots of info here.

Aftermarket crash bars may also have a resonant frequency in that range.

Do you have crash bars? Does it also happen in the same RPM range but in different gears? And when the resonance happens, do you feel it in the crash bars (touch them with your hand, or put your leg against them)?

If it is a resonance in the crash bars, then you can typically move the resonance to a different frequency (RPM) by adding some weight to them. For instance by adding an additional rubber block around the bars. And sometimes tightening the crossmember between the left and right bar helps as well.

Acceleration through 2-3K range in first gear should be over in a fraction of a second so hardly intrusive.

That said, what condition are the chain and sprockets in? Badly worn can cause some odd vibes. Aggressive tread tires also (especially at low rpm.)

If neither of the above, I'd start by checking the tightness of all the engine mounts. Next would be checking throttle body synch and checking for vacuum leaks.

I see a LOT of DL 1000's with around 30K miles that are "new" to owners. I suspect some of that is because the previous owner didn't know where these vibrations were coming from and simply sold the bike rather than worry about it.

Your mileage and symptoms are classic "clutch chudder". No DL 1000 is immune to it. I suspect it is there in all the gears to some degree. I have a section on my website you might want to read about and try, Chudder Test. I suspect that will net an obvious change in vibration, meaning the clutch basket is the source of most of it.

Yes, I run a business fixing these clutch baskets so they are better than new and stay that way. But, I started out here just like everyone else and found a way to fix my DL 1000. That progressed into the WERKS modified clutch baskets. If you have any questions about any part of the process, e-mail me [email protected]

I had the same issue and last week installed one of the WERKS clutch basket kits. Those vibs are GONE. Terry has excellent customer service and even a video on his website showing you exactly how to replace it. I highly recommend it.
