Sure does... Except if you read about that, those are listed as only for the TC88.

 

Part Number 1999
Stops Oil blowby mist, PERIOD ...

Fits all TwinCam Based Motors Complete Kit for Both Cylinders

The MYSTFREE was designed and patented by Tim Doherty, founder of

Doherty Machine, specifically for the TwinCam 88.

 

Yes The photo is of Doherty Mystfree I was only using it as an example of what breathers I was talking about. One of the original responders thought I was talking about the external breathers on the intake.

Mystfree would probablly work except it doesnt say if it will work on a 96" but I know Harley came out with a new design for the 2011's so Id like to use that instead.

Harley part number is: 17025-03A. Check out the article in: American Bagger, Issue 10, Vol 05, November 2011, page 118 (this is the current issue still on the book stands). Wonderful tech article on how to replace the old plastic valves with the new metal ones
