Hi everybody,

any idea if this is normal or I should be worried?



Thanks in advance.

Might be a broken wheel  bearing. Zero's are notoriously bad. If it is the case it will cost you 100 $ part+work

The sound comes from the motor or somewhere near the motor pulley.

I would be concerned.  I did a quick search and found how to change the bearings.

Or this link in the first one suggesting a loose magnet.

If your bike is still under warranty it would seem like a good time to have your dealer check out that noise. It sounds very odd to me. 

[sharagan]

I will definitely go to the dealer with it first thing on Monday, I just bought it new last September. I will post the progress here.

How tight is the belt?

[stevenh]

Probably not related, but it looks like you've got some nasty cracks in the belt?  Too tight?

Hi Steve,

I have the manual tension meter and the tension is at 30kg, I check it regularly. The bike has only 1600km (1000 miles).

Should I bring the cracks to the attention of the dealer?

Thanks for the observation.

[sharagan]

Can it be, that the belt is making those sounds?

[mdjak1]

Maybe you could loosen the belt up some and see if the noise is still the same.   Or even pop the belt off the front sprocket completely and try to turn the motor by hand, feeling for any grinding resistance.

[sharagan]

when loosened or tightened the noise is still there.
when I removed the belt the noise was gone.
from my feeling it still can be the motor bearing as the pressure from the belt affects it or it is generated by the pulley and the belt.

Perhaps the belt is not aligned on the pulley correctly or the clicking is caused by a deformation of a section of the belt.

I played around with the alignment again and also the tension....no change at all, no matter the angle or tension. Thanks anyway for the hint.

My FXS is still at the dealer, the reply from Zero according to my dealer states that the noises are completely normal.

...and I have the feeling that this will be the case until the warranty is valid....
