Yes for sure. I bought some engine enamel black for the pulleys and I already have a new idler pulley. Right now it’s just getting mocked up so I know it all fits, tomorrow it all comes back off for cleaning.You're in there.... might as well clean & rattle-can those pulleys. I also suggest a fresh tensioner + idler pulley that way everything serp set-up wise is fresh. If not in the budget, I get it.
