DLC Coated Lifters

8 or so years ago I actually looked into having some custom modified rocker arm assemblies for a vintage motorcycle DLC coated and found a company in my region that would do it. I had a couple sets I was wanting to send but the cost was extremely prohibitive. Can’t recall the exact dollar amount but it was a deal killer. Would have needed a bunch more sets done to defray, eventually sell to recoup some of the cost. Sure would have been nice though.
