Front sprocket change

I think of it as a swing arm protector. Without it the chain would wear away the top/bottom surface of swing arm-its just Japanese not having exactly right word for it!

"Rubbery"  :lol

I dont know of anyone on here who has had to replace a completely worn one, your chain would have to be so slack as to wear through it that you would have other problems, like it jumping off

If you've adjusted the chain by moving the rear wheel you may have slightly put it in a different position.
So the noise "could" be the chain cutting a new path on the plastic chain guide?
Tends to sound worse when people upgrade to new heavier duty chains, it makes a buzzing/rubbing noise.

If its cutting a new path, its too tight.

Or a heavier than standard replacement chain, they need a bit of bedding in when first fitting, which is what causes the loud noise. Had it myself, and others on here have had it as well before, it's nothing new.
