    FZ6 S2 weird noise coming from sprockets

    Hi all,

    Can anyone clear this out for me, it's been bugging me for a while. Is the sound the sprockets make in this video: https://youtu.be/aw0LuOk7D9I normal or not?

    Thanks

    That's on the loud side. What is your chain slack/free-play set at?

    Re: FZ6 S2 weird noise coming from sprockets

    That OEM, front sprocket is clearly worn out. Once that "plastic" edge starts going away it's time for a new one.

    How many miles on the chain and sprockets and as noted above, what measurement do you have the chain adjusted to?

    Is the bike "new" to you and do you have an owners manual (for how to adjust the properly)?

    And no, that noise isn't normal.. A worn chain and sprockets WILL make all kinds of racket..

    Re: FZ6 S2 weird noise coming from sprockets

    Definitely new sprockets and chain needed; the links are hitting the sprocket; indicating that the sprocket has worn excessively deep or the barrels and pins in the chain have worn excessively due to lack of, or incorrect, lubrication and maintenance. Check how much movement there is of the rollers on the barrels. Either way, I would consider it a risk riding with it like that.
