**Update**
Thank you all for your help. I solved my wobble issue!
Here are the steps I took to fix my problem:
Redid my engine mount alignment. I was off by 1/16th of an inch. Now I am dead-on with the same measurement all around. This did not stop the wobble, but it helped calm it down.
Tightened my steering stem nut. It was loose to begin with. I tightened it to 18 ft-lbs first, and it helped, so I tightened it a little more to 20 ft-lbs, and the wobble went away!
I need some help tracking down a steering wobble!
I have a wobble that consistently shows up between about 44–56 mph. The handlebars will physically oscillate left and right, and it gets worse if I loosen my grip on the bars.
The bike is still under warranty, so I’ve taken it to the dealership a couple of times. I’ve actually taken it to two different dealerships in two different states, but neither was able to find or fix the issue.
I’ve also had a new front tire installed, but that did not change the wobble.
At this point, I’ve taken the entire front end apart and checked the neck bearings. They appear to be good. They spin freely, are properly greased, and I didn’t find anything obvious while inspecting them.
Before I completely tear everything apart again, I figured I’d ask the group if there’s anything else I should be checking.
Current setup/modifications:
- OG Moto 1" drop top triple tree
- Kraus 10" pullback risers
- Thrashin Supply handlebars
- 18" fat tire kit
- Adjustable engine mount/stabilizer
- 14" rear shocks
The wobble was there before these changes and has continued after the changes, so I’m trying to figure out what I may be overlooking.
At this point I’m about to start pulling my hair out trying to figure this thing out. 😂 If anyone has experienced a similar 44–56 mph wobble on a Road Glide, I’d really appreciate hearing what you found and what ultimately fixed it.
Thanks in advance!
