After installing the springs and riding for a week or so, I've noticed that I get a wobble at higher speeds. (90-110)

I suspect uneven oil level.

Now I followed the install by Alphamazing and there was never a point where the actual oil level was measured inside the forks. From what I'm understanding, there is a difference in the bottom ends of the left and right forks so a different amount of oil will be necessary to create an even amount of air space. Again, it's the air space that's important to be even and not actually the amount of oil, right?

Anyway, to measure the oil level, I'm going to have to crack open the forks, remove the spacer washer, and spring, then measure the oil level and adjust so that both sides are equidistant.

Am I missing anything else? Am I looking in the wrong place for my problem?

I can't imagine a minor difference in oil level would be a culprit for high speed wobble. Since you had the front end apart to do the change, did you check your bearings? Are you certain everything is reassembled properly? Is the front axle nut torqued properly? Is the spacer in properly? Is the speedometer box assy installed properly? (it can catch on its stop and pinch between the fork and wheel hub). Are the front forks aligned properly?

Well what's a minor difference in oil level? From what I've read 10mm makes a huge difference in the feel of the bike.


Bike has less than 9000mi. Wheel bearing isn't the issue.

Everything is reassembled properly as far as I can tell.

Axle nut was torqued to spec.

By spacer, I assume you mean the piece on the right side/caliper side. Yes, both the spacer and wheel speed sensor on the other side are seated properly.

How am I to check the fork alignment? I installed the bracket that supports the fender at the same time as I was installing the axle so that I would have two points of alignment instead of tightening one first and causing that to skew the other.

Is there a specific test?

I'm looking at fork oil because my symptoms can be caused by that problem without any other symptoms being present. My bike does not pull to one side or have a vibration.

Is it true that there is a different amount of oil needed to produce the same level in the forks?

1. On center stand
2. Someone pushes down on back or do something to get front wheel off the ground.
3. Wiggle, twist, whatever. Feel for anything lose or not tight

Did you remove the brake rotor when doing your work? If so, it may be on in a different position and your wheel is out of balance. My dealer always balances a tire with the rotor on. They insist on it because rotors are not always perfect.

If your getting a wobble I would check your steering head bearings as well. Make sure they are properly adjusted.

I checked the fork oil level and the right side was a half inch higher than the left. Leveled it off. I'll see what that does.

I also think I have too much oil in the forks.

When I try bottoming out the forks, hard braking, bouncing on the front end, even popped a small wheelie, my zip ties are just under 2" from "physically" bottoming out. I should be seeing them a lot closer right?
