Personally, I recommend against changing the look of the stock '09 Street Bob motor ... I suppose it is personal preference, but I like the nostalgic look of the silver bottom end and the black top end .... so much that I mimicked the look on my '05 Dyna ....

A lot of the old Pans, Shovels, etc had that look with raw cases and black cylinders and heads ....

Black pipes look killer with the silver motors

 

I love my one year only, collector edition, silver engine Street Bob...I'm also a member of the Red Wire Club...

Too much black hides everything.....you need some contrast.

 

I unknowingly joined this club, but I'm a proud supporter! Love my silver engine.
