There is no need to worry. That is exactly the way the wheel bearing spacer/bushing is supposed to operate. If you install the axle without the wheel bearing spacer/bushing, you can tighten the axle too much, and it will put lateral pressure on the inner races of the bearings. This will make the wheel hard to turn, and the lateral force will also damage the bearings. For more information, read replies #6 through #13 at the following thread.

Thanks Spud. Looks like everything is as it should be.

You're welcome. You raised an excellent question, which deserved a detailed answer.

[Adjuster]

Thats some good bearing information on that Guzzi forum.

Indeed, that is an informative thread.

As a general rule, trust the engineers who designed the bike. The put the wheel bearing spacer/bushing inside the hub for good reasons.

Adjuster and Spud definitely a good question and answer. I was wondering that myself. Thank you.

Ok an update. I tried to make an online appointment yesterday with the main service center here in town (we have 3) Its the only one that has online scheduling. For warranty work the first available was December 2nd . So without an appointment I went to one of the other centers. When I arrived at 415pm there were 4 mechanics standing around talking and a guy behind the counter. I explained what I believe is the problem and one of the mechanics took it for a ride. He heard the noise and they agreed. But they told me the official technician was out for the day and I could leave the bike. I declined and said I would go back today after work. Keep in mind I dont speak Spanish but was armed with my video that shows the noise and the spanish translation for ball bearings.

Another thing..The bike stalled on me yesterday without warning and the front brakes are getting very jumpy. I have been riding really easy and hadnt noticed this before. I use the front brakes exclusively on the street and will have them check this too. Soon I want to replace the pads with the ones Spud recommends if whatever they do at the service center does not make me happy. It has stalled once per day of riding but yesterday there was nothing I could point to that was maybe my fault. I was just sitting at a traffic light idling. Will keep the updates coming. But damn riding this bike always put a smile on my face. Loving the sound, the power, the handling, the style, the whole Zong package.

If you lift the front wheel, and spin it, does it wobble? If a loose bearing causes the wheel to wobble, the brake won't work properly. See reply #6 at the following thread.

Since your bike has a carburetor, you will need to adjust the jets and pilot mixture screw to tune the fuel mixture.

Once again, I caution you not to ride the bike very much until you get the front wheel fixed. Riding in heavy urban traffic is especially dangerous.

Spud thanks for the info and the link. Back to the shop this afternoon and I hope to get everything sorted out then. Really appreciate all the great info and advice here!!! Took a taxi everywhere yesterday to avoid riding except to the shop. Today I am on the bike but work is only 5 minutes from home and the shop is only about 8 or 10 from there. We dont have any highways here so speeds rarely get above 30mph in my normal day to day riding around town. Keeping a firm grip on the bike when riding expecting the worst and hoping for the best.

I want to try and tackle all 3 issues in one visit today. Brakes, Bearings and Carb. I hope they cooperate at the service center and I can get that done. The only thing I could probably live without them fixing today is the carb but we will see what happens.

[SpudRider]

Good luck. Please do keep us updated.

The service center pulled the wheel and the bearings today and there was NOT a spacer between the bearings . They had one fabricated and installed it along with a new set of bearings. The front wheel spins nice and free now and the axle nut can be tightened to spec. They also checked the brake issue and I am not sure if they made any adjustments but they are working fine now. Very happy with the fast and friendly service I received today from the guys a Maxi Motors Del Meta in Villavicencio.

[SpudRider]

Good for you.

As I stated in post #37 of this thread, the missing spacer would definitely cause problems with the front brake.

Is there no shoulder for the bearing OD to register against?

The outer race is supported by the hub.

Last night the tech lowered my idle speed down to 1400rpm. I think it was running at about 2100rpm. The bike stalled on me on my way home but I didnt give it a thought. This morning the bike stalled during every stop on my way to work. That was about 5 times in 6 minutes. Sometimes it took 3 or 4 attempts to restart. To avoid this I kept a little tension on the throttle to keep the RPM´s up but this shouldnt be. Reading around I am now concerned I am developing the stalling issue that some have reported. The bike now has a total of about 70km on it. Any advice on the idle speed? Any other issues I should look at? I have read some posts about charging the battery, adjusting the carb, etc. but everything was fine the first 69km except the wheel bearings and that was just a sloppy assembly mistake. Am I being overly critical, is hypochondria setting in after reading so many posts on so many sites about issues??? Should I crank the idle back up and not worry about it? Should I give the bike more time to break-in?

This is the carburetor version right?
For a new, not yet broken in bike, 1400rpm is a bit low.
Adjust it with your fingers, using the knob below the fuel petcock, turn it a bit clockwise to raise the idle a bit.
I found in my bike that I use this adjustment even instead of the choke when cold. Choke causes the motor to stall almost inmediatly. When I first fire it up in the morning I rise idle to about 2K, wait a minute to get it warmed and then dial it back to 1700.
