• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Finished lots of upgrades and farkles and now have Front End Wobble

Took my first ride since Christmas this evening after doing all of my mods. The only thing I did that could affect handling was put on Baja Rons new sway bar and I took off the front wheels to install the Bright Sides led lights. When I hit 38 mph the front end started shaking like crazy:dontknow:. It got worse the faster I went. I stopped to turn around and after going into reverse I pulled out and the shaking stopped. I went about 3 miles and had no shaking at all. Then when I headed back home the shaking came back.

The wheels were both put back on the correct side!

When I got home I checked front tire pressure. It was 16.0 left and 16.5 right. This is lower than I normally run it but I don't think it should cause the shaking.

Any ideas? I won't get a chance to check it until tomorrow evening.

Note: I am not attempting to bash the sway bar. I just need to figure out what is going on.

There isn't any way the sway bar could cause a wobble. I agree that you need to check the wheels as they could easily cause the issue you're experiencing.
 
Have to agree! Sounds like loose lug nuts. This is the one thing I check numerous times, and then again before driving, if I doubt myself! Better safe then sorry!:thumbup:
 
Have to agree..!!

the sway bar will not cause the wobble. I'm sure you tightened the wheel nuts on the ground to the recommended torque specs. If not re-torque even the tire pressure to what your used to and ryde again. Make sure you did not swap wheels they are rotational...good luck..!! :thumbup:
 
Shakyng after installed Sway Bar

Y concur with the others, What else could yt be? YF yt ran good before the Mods upgrade and you took off the front wheels? We can only guess you did not tyghten the lug nugs. :lecturef_smilie:
 
Did you switch the tires from one side to the other? The tires are directional and need to be remounted before rotating

And I really think you should change or have the Title changed as it is NOT the sway bar causing a wobble. A wobble would come from a rotational motion or imbalance.
 
I have noticed that if my Spyder sit for a while I will get flat spots on the tires. I have a vibration for a while but after the tire warms up the vibration goes away?????
 
Do you have Ride-On installed in your tires? First ride on the Spyder this year about jarred my fillings out. Ride-On coagulated over the winter, leavin one big blob inside the tire until it warmed up a bit.
 
The sway bar wouldn't cause anything like that. gotta be a tire , rim issue. Even without a sway bar it would simply sway more and not wobble. Off road jeeps and trucks often remove teh sway bars to allow the suspensions to have more flexability.

You noted since Christmas and ALL my mods? You need to backtrack and find out which mod could have caused the problem. That's why many recommend ONE mod at a time!
 
Installed Baja Ron Sway Bar and Now Have Front End Wobble

Do you have tire sealant in the front tires? Sometimes I got a shake for a few miles after the Soyder sat for a few weeks or months

The title is a bit grim and it wouldn't hurt my feelings if it were changed.

I think those who mentioned swapping tires may have got this one right. I didn't think of that. The Spyder is not like a car. The tires are directional (designed to rotate only 1 direction) as opposed to the average tire which will run just fine either way.

Great suggestions by everyone on this. Hope he figures it out and posts what the solution was.

Change the title to

I just did a bunch of stuff to my bike and I have a wobble.

In his original message he did state "The wheels were both put back on the correct side!" so I don't think that's the problem.
 
Maybe jack the front end up and give each of the wheels a spin, see if the is any pulsation or even a broken belt in the tire. A broken belt you would see in the tread side to side or even up and down.
 
Time for some good old-fashioned troubleshooting. The swaybar should not have caused an issue, but I suppose it could have enhanced another problem, or something could have gone wrong following the installation, like a broken sway bar link, loose bolts, broken bracket, etc.

I'd start at the wheels. Make sure they are well seated, with nothing lodged between the wheel and the flange, and that the lugs are all torqued properly. If you added Ride-On in the off period, or something similar, it could be the cause...especially if the Spyder was not ridden immediately following, as they specify. If there was Ride-On in the tires and they were laid on their sides for a long period of time, that could be the cause. Make sure the wheel balancing weights were not knocked off during the dismounting/mounting process. Spin the wheels and look for axial or lateral runout. Double check your tire gauge to make sure it is reading accurately and that the tire pressures aren't actually too low. BTW, the tires should be the same pressure on both sides.

Next I'd look again at the swaybar installation. Make sure it is still properly centered, the bolts are all tight, and the links are intact.

From there I'd start looking carefully at the front suspension. Look for loose shock bushings, loose tie-rod ends, or loose ball joints. Be sure an a-arm or tie-rod is not bent...it is easy to do accidentally with a jack or by putting a jackstand in the wrong place. If nothing else is found, an alignment check may be in order. From that point you would need to look carefully at the steering, steering sensor function and calibration, swingarm bushings, rear wheel bearings, etc. Those are usually a job for your dealer. Best of luck in your search. Let us know how things come out.
