Let's Talk Wobbles

Everyone talks about the decel wobble. WHEN LOADED, my bike wobbles at around 35mph whether I am accelerating, decelerating or going steady. Stock suspension. Forks raised in tubes 13mm. Lowering links, but rear is at or near stock height, but this does not seem to matter as wobble is present at all adjustments of lowering links. NO WOBBLE when not loaded.

What say you?

Engine Guards; Bash Plate; Centerstand; 1" Bar Risers; Adjustable Lowering Links; OEM Top/Side Cases; EB Headlight Relay; OEM Handguards; Fork Brace; Piece a crap Windscreen; Broken Shift Lever (Tap/Bolt/Duct Tape); New Tires (but I coulda run on that plugged rear another 4k)

What tires are you running. The Shinko/Full Bore I use have a "walk" at low speed , but the Factory Trailwings were all over the place. Glad those are gone.

Lord , if I have to look like a Power Ranger , can it at least be Amy Jo Johnson?

Need whole story

tires age mileage pressure you run

Mine only moves when there is a big load like camping

Steering head bearings stock are inadequate and need frequent adjustment

A new tire solved my wobble issue. The OEM Trailwing was cupped bad so I installed Pilot Road 3 and the wobble went away.

First noticed this fully loaded for 2 month trip, running brand new Anakee IIs. 10,000 miles on that trip and as far as I can remember the wobble was everpresent. Put brand new Anakee IIIs on before fully loading for 5 week trip. Wobble has been consistent for 8000 miles. I generally run 33 PSI in front and 38 - 41 PSI in rear. I purchased bike at 10k and have put 30k on it.

I can manage it, but wobble is noticeable even with two hands holding bars lightly. If I take hands off bars, it would eventually wreck. Wobbles only when loaded.

If you lean forward does it go away or get better. Have not experienced it on the Wee yet, but my KLR would do it at speed when ever I used to put my feet on the rear pegs. Too much weight in the back lightens the front end and depending on the tire tread, could enduce a wobble. If that is the case you need to drop the front end or raise the preload in the back and see if it gets better.

if your bike is lowered at the front,and at the back, then it really shouldn't affect geometry. The fact that you say it happens when it's loaded, means that you may very well have too much stuff on it, or the fact that the front end is light. Weight bias.

does accelerating improve or worsen the situation. does compression braking improve or worsen the wobble?

In my experience, a wobble is fixed by more power. Throttle fixes everything

Yes, should have mentioned I am probably 155 lbs. with all my gear on. Tank bag may add another 5 lbs. Wobble only seems to occur between 30 - 35 mph and when bike is loaded. Accelerating makes it go away - but then again my hands are on the bars. Does get worse as it decels with hands off bars. Don't know about compression braking because again hands are on bars.

I had a bit of this issue when taking slow sweeping corners especially when not on the power. A discussion on this board said it may have been a number of things and it was focused down to the steering stem nut maybe being loose. However, I adjusted my pre-load nearly all the way positive for a camping trip that had me loaded heavy and it seems to have solved the problem. I think my fat ass just needed more pre-load on the rear suspension. Maybe this is the problem when you are loaded up?
