Nice assembly, nostalgia vibes 0 people found this helpfulBought this to utilize on my 95 Sportster w/ 1250 kit & Mikuni HSR45. Should offer plenty of flow to maintain peak hp numbers. Still building the bike so I can't attest to it's performance yet, but it looks great. To customize this piece, I sprayed it with matte finish to match my black anodized finned handlebar clamps. This kit bolted right up to my CV adapter without issue. It clears the leg nicely with forward controls. I already had a breather setup, which looks the same as the optional one offered. I put breather type systems / catch cans on all my vehicles, sending that oil vapor back into the engine is not good, as DK has demonstrated. The backing plate is surprisingly heavy, aluminum might be a nice option. Overall it fits the aesthetic of my retro mod build nicely, quite pleased.
