I got the DK kit for the stock breather bolts. It's not here yet, but I've sorting out how to run the tubes like TC did to below the AC

Don't think breather bolts will work with the high flow ACs. Never tried them though so I could be wrong. Good idea.

Running breather bolts, my bike looked like it was sitting next to a fried chicken competition after every ride. My breather bolts are in a bag in my spares box

What is the point of a filter? The crankcase is positive pressure so your not filtering anything. All you are doing is saturating the cotton of the filter. I just went with breather bolts. Keep the oil level at half on the dip stick and you won't have to worry about a fine mist of oil coating the motor or anything else. The other plus of breather bolts is that you don't have to look at the hose lines and filter that most people use in their setup.

All things being equal, some Twin Cams do seem to have more of a carryover problem than others; even with methodical oil level and viscosity, certain T/C's will have a problem with carryover; and I've never heard a reasonable explanation of why that is...

I put 1/4 inch vacuum hose connectors to a "T" and then got a 1/4 chrome faucet supply from my plumbing store bent it nice and ran it down to the frame and put a black zip tie on it works and looks good
