Guys,
While cleaning my VTX 1300 R, I noticed the crankcase breather hose was kinked. As this has happened before, I decided to look for a solution.
What I came up with, is something I like to share with you guys and I’m very curious about your comments!
I drilled a hole in my frame between the coil and the radiator cap. I stuck a nipple in the hole and welded it on. I cut the original breather hose to the desired lenght and connected it to the nipple.
Now my crankcase fumes are disposed of in my frame. So no more oil in my filter house and no more kinked hose in the future. All the extra oil will drip in my frame which, in my humble opinion, is a good thing.
Since this modification I’ve driven around 400 miles with my bike, and I have not noticed any problem.
So. Let me hear your comments. Do you think I’ve done something stupid or not?

It's not just pushing out oil/fumes/etc. It also sucks in. I don't know where else there is an opening in the frame but you're letting unfiltered air directly into the crankcase.

I applaud your ingenuity, desire to work on and mod your own stuff.
But...
It does seem like in this instance you may have created a solution for a problem that does not exist.
At the very least maybe a little over engineered, wouldn't a piece of hard line/pipe/pipe fitting/elbow etc. in the part of your original line that was getting kinked solved the problem?
Regardless it is cool to see what people come up with (y)

What if the oil is dripping onto your garage floor or the road in front of your rear tire? What if the frame is sealed and you build up pressure and blow your shift seal? While the crankcase breather hose can kink if not put back in place properly, it is easy to determine if this hose is passing air and to adjust it if it is not.

There is a lot of moisture other than just oil... You you are introducing water to the inside of your frame.

I think it would have been easier to just do the Pair valve removal (DE-SMOG).

The pair mod does not eliminate the crankcase breather hose.

Personally, I wouldn't want all that gunk going into my frame.

More reasons not to do this than to do it. Not our bikes though.

rmack2, I am sorry but I have no idea what you are saying or asking. Please try again. Oh, and I can assure you that I have never belched fire. It may have felt like fire but it was just too much hot sauce and not real fire.

When the carburetor puked gas caught fire it melted the breather hose that goes to the back of the airbox the one that's real close to the pair valve hose & it melted a big portion of the airbox.
It didn't damage anything else that I could see it was kind of a flash gas fire and I put it out
I haven't been able to find a good picture of that breather hose or a part number?

Did you look through the appropriate parts diagram on partzilla or another online parts website?

The breather hose is a two-piece hose with an adapter connecting the two hoses. Part # 13 & 14...#13 attaches to the top of the front cylinder on the left side, and then it routes between the cylinders and over to the air box.
