Primary rollers question.

[Honk]

I was greasing bearings today, and when I went to blow out the cluthes I noticed that the Primary rollers were bronze color. Don't these start out sliver? They seemed to spin just fine, but it looked like they were worn. It also looed like maybe a little rust was in there on this area. Anybody seen this? Thanks for any info, Honk

I had lots of rust on mine at the beginning of this year, I just rode it a couple times and it was all gone...

they sometime rust up a bit, just make sure there spinning freely
