Front wheel wobble

283 Views 28 Replies 7 Participants Last post by  taco_to_go
For around a year I have noticed a mild front wheel wobble:

1. Low speed, about 30 or less
2. Under deceleration if I pull off power and loosen grip on the bars
3. Mild at first but shake increases if allowed
4. Not there under acceleration or cruising

I have tried:

1. Keeping proper inflation of a very good front tire, size 110-90-19
2. Loosening the forks, eyeballing alignment, insured all clamps ok
3. Checked for play in wheel bearings (none)
4. Squaring up the windshield and lower deflectors
5. No disc brake rotor dragging

The bike has 43,000 mi; never damaged anywhere; fork oil should still be balanced from the seals I put in 3 or 4 years ago; rear shocks not pressurized with air but suspension equally set.

Anyone else ever deal with this?

I did took the handlebar cover off and found the stem bolt was finger tight. I put Loctite on the torch down. Haven’t had a problem since I also use a super brace that ties the forks together, just above the front fender, makes a significant difference far as I’m concerned, you might wanna look into it

If you look on top of front fender you can see how it follows the contour of this fender without touching it, and it locks to both forks really eliminates any wobble and it’s very well made Also has little flaps to cover the lower fork so you don’t get stone hits.it’s very high polish aluminum

Any possibility that you've lost a balancer weight? That's the only thing I can think of. @Spockster usually has some good advice on stuff like this.
I started getting low-speed wobble as soon as I replaced my front tire. I didn't feel like dealing with getting a replacement, so I just hold on to the handlebars when braking :oops:. Tire tire profile (either from factory or due to wear) can cause this, as well as an unbalanced tire. Of course, any potentially loose/misaligned elements in the fork/head should be checked.
Just the fact the the wobble comes and goes and isn’t constant would make me check the if the tire/wheel is balanced.
Also check your frame rail on the stator side of the bike for rust(the solid side)

The turn signal on the right hand side is crooked, did you break it?
The aftermarket turn signals will sag from heat when I put bike away I attach buggies to pull them up and that will last for a week . They are good quality but heat effects them

New tire was balanced?

Check the stem/neck bearings?

Since you eyeballed the fork alignment you might need to reset them by following these steps.

I've been meaning to mix up a batch of JB WELD (or some other permanent Epoxy) and mold it around those existing black rubber sections. Once cured, sand it smooth and paint it. But, might just be easier to order new ones. Mine are still holding up, though.
Even the new ones are aftermarket and the same thing is going to happen when I was rebuilding that bike I ordered or four from a company who’s 100 bucks for all four that’s just the way the rubber is now . When I put bungees on them and lift them up like I said, they’ll take a shape where they’re straight but then you go out and get in the sun they get warm and they Sag again
I’ve seen one guy use a cut tube of a ball point pen inside the signal arm to keep them from sagging. I was going to try this but I realized my signals were pretty dry-rotted so I just replaced them.

Signals work fine they just look like they’re falling off or broken. Yeah they’re a little unsightly but like I said, if I buy four more, I’m going to have the same thing happen. I don’t even know if the part is available from Kawasaki if it is, it’ll be a fortune.
I definitely get your point, I bought mine from Partzilla about 3 1/2 yrs ago. Then I dropped the bike so I scuffed the new one and I said “eff-it” it’s not broke just scuffed” didn’t bother replacing it again. I’ll fab up something if I have to replace them because I’ll have 8 to work with lol.

I just checked oem front signals discontinued rear turn signals available 55.00 and 43,00 shipping from megazip I will stay with aftermarket ones thd main difference is the rubber is more brittle with oem aftermarket ones are to flexible and will sag

There's all kinds of OEM bullet-style Harley Davidson signals out there rather cheap. They're solid and heavy, too. I had a pair on my '95 Yamaha Virago, and it took very little to make them fit perfectly.

A lot of those HD guys change out the stocks ones for aftermarket, and thus there's a lot of those OEM ones for sale in excellent condition, cheap.
Thank you I will look into it
