2017 F3-T, SE-6 only 6,000 miles, (I am fortunate to have great riding areas minutes of the house). Checked every 6 months for red dust and again just today. NADA ! And I want to keep it that way so am going to be proactive and like some have suggested, remove pulley, clean it, inspect it, if OK reinstall with moly paste and blue loctite on bolt.

HOWEVER, I recall early on some were saying the bolt could be stretching past tolerance and should not be reused. Newer threads aren't mentioning this.

OK experts: reuse or replace?
