You will have to come up one of these days Bill and I will tighten that stem bearing for you.......then you can ride back to Omaha hands free

Sounds good 2 me!!

I went ahead and ordered the All Balls tapered bearings just in case I got in there and needed them. The stock bearings looked good and still had an acceptable amount of grease but, since I already had the front end off I went ahead and changed them.

Results - ALL the head wobble was gone. I could even lift my hands off on decel which was better than new.

I thought for sure the tire was causing at least some of the wobble but It looks like I was wrong. Also, I think if I would have cleaned and re-lubed the stock bearings that I would have still had good results. My opinion is that these head bearings are a hair loose from the factory and over time/miles they will break in just enough to allow a wobble. The manual calls for 21 ft-lbs. I went with 25. I also run 40psi front/back.

Good for you Dogleg! I am tired of telling people to tighten that bearing so I am going to stop doing that. When I tightened mine, I still had the partially worn tire on my bike because I was not going to put a new tire on and still have the bike shake and wear the tire out. After I tightened the bearing and the bike was not wobbling with the same old tire then I went ahead and changed my tire. I think it has been at least two years now and thousands of miles and still no wobble

Thanks everyone for your replies. I will wait for the cold and pull it apart and go with the new bearings.

Thanks again

Not sure Smoky, I know the front tire runs with the wide side of the V pattern rolling forward and the back runs with the point of the V running forward. Could the V being forward running on a front be more apt to move the tire to road condition like grooves, tar patches, cracks? Figure theres a reason its supposed to roll that way.

Do you need any special tools to tighten the bearing?

I think the main reason is for water dispersion, I never noticed any handling issues when I accidentaly mounted my front wheel backwards, in fact I probably wouldn't have noticed except for the abs not working.

I got this explanation off the internet

Directional (Unidirectional) Tread Patterns
A directional (also called a unidirectional) tread pattern is designed to roll in only one direction. It incorporates lateral grooves on both sides of the tire’s centerline that point in the same direction and result in v-shaped tread blocks. These grooves enhance hydroplaning resistance at high speeds by pumping water more efficiently through the tread pattern. Unless they are dismounted and remounted on their wheels to accommodate use on the other side of the vehicle, directional tires are to be used on one side of the vehicle and are intended to be rotated from the front axle to the rear axle. If different tire sizes are used on the front vs. rear axle, the tires become location-specific and prohibit tire rotation unless remounted.

This would also explain why snow tires on a lot of vehicles are only meant to go on the one way for traction and grip in ice and snow.

Yes you need a special wrench to make it easy. There's probably a hard way to do it without the wrench but I just bit the bullet and bought one figuring it would be way cheaper than asking my local bike mechanic to do the job.

Mine came from Amazon at $33 shipped

You can use a dull chisel/ metal rod and a hammer to spin the nut too. The tool id-man posted would be great to have though!

Ive used a drift punch and hammer to tap it to the proper tightness.

Worked for me too!

Had the same issue with mine, took it to dealership and found out that the fork bushings were bad, the head bearing was loose and tire was slightly out of balance. I had all of that repaired or replaced and still have the wobble, dealer called Kawi direct and the first question they asked was what kind of tires I was running, mechanic tole the Metzler 880 and their reply was "call back when he has OEM tires back on it". Dealer put a front wheel from a Vaquero they had there with 3k on origional tire and it still wobbled only at a lower speed. We then tried lowering the air pressure to Kawi's suggested 28 psi, then it shook so bad I had trouble holding on with both hands, so took it back up to 38 psi and went on my way. My next step is to try the balance beads and when it's time for new tires I will go back to the origional equipment because the bike didn't do any of this when I first got it....not to mention I can buy 5 tires for the same price I paid for 2 metzlers.

If the Vaquero front wheel with the OEM tire did not cure the wobble how is going back to OEM tires going to fix the problem ?

id-man · 09-02-2014, 10:48 AM

jtrkr220 that story is messed up. I'd be real pissed if that much work didn't fix a problem. FWIW my bike had a vibration at 85mph which was cured by dynabeads. That's not the same as a wobble but perhaps is an indication that these bikes (probably all heavy bikes) are sensitive to precise balance...it all contributes to erratic feel in the handlebars. Good luck with the beads and getting your wobble resolved - it's beautiful when it works!!

I am suffering with the same problem. I put new tires (ME880), new head bearings, new wheel bearings and replaved the fork oil; it's still there. At the suggestion of some on this site I increased the preload (I used 55 inlb), the wobble started at a higher speed about 40mph and seamed to be more severe. So right now I am living with it (just got back from a 2K mile trip), when I get time I'll increase the preload some more and see what happens.
