I've never liked having my crank breather hose open to the elements. When I purchased my new bike I tore it down to see what could be done. Coming from my 2012 I was hoping the new bike would have provisions for attaching the hose to the air boot. Turns out it only had the boss for the elbow. Ok, no problem I simply ordered the elbow and clamp from the previous gen bike. So the first picture here illustrates why this is an important mod in my book. This is the end of the hose that attaches to the valve cover. Note the particles of dirt after only 6 hours run time in non dusty conditions.
So off comes the air box.
The required parts.
A closer picture of the boss where the elbow will go.
The elbow installed after cutting out the center with a hobby knife. It's important here to cut from the out side part of the boot.
Now I noticed that the hose is slightly larger in diameter and doesn't clamp tightly enough to the elbow. I found a small section of shrink wrap and applied it to the elbow to make up the difference. I reinstalled the air box and pondered the best routing for the breather. Using the existing hose and shortening it only slightly I wrapped our around the front of the throttle body above the header. In this configuration I was able to avoid kinking the soft hose. I also noticed the extra protective layer on the hose is perfectly positioned above the header. Surprisingly this configuration also keeps the hose further from the header than stock. Here's the last pic I have.
I'll try it out tomorrow and let you all know how it works.
