Got it free under the s&s power stimulus. The header I bought went on my t.c.roadking, but requested the a/c for my M8 Softail. I already got a ventilator I like, but thought I'd play around with an external breathers on this buttugly stealth. The diameter of the black boring plastic cover is approx 5.5". Does anybody have a link to some decent looking covers that will fit this thing? I know S&S does, but I don't care for the look on this bike. Any info / links? Thanx guys. Be safe.

 

I know, I know. Boring question. Any suggestions at all? Turns out it's about 5" diameter. Flat circle work too.
