The breather vent mod is to prevent oil entering the carbs (thru the air box), I had started this thread because I had hoped to see other different mods for this solution, so far I have instructions, pics and descriptions of two different methods. They do work, but for now I believe my modification is going to be different. The only reason you would probably(?) need this mod is if you are changing internal components, I could be wrong...but that is my idea of it. I am adding the 840cc kit presently, and for this, I will need to find another compression relief in the motor (crankcase or heads) - haven't decided where mine will be yet. This has been an ongoing situation with the V-twin from Kawasaki for quite some time as I understand. I am not for sure, and I only posted this cause of my pure ignorance of the engineering involved. Personally I believe it is best to get the compression gases out of the carbs (ie.not EPA approved), and to be a free flow escape, my opinion is that unburnt gases or any gaseous pressure should not be forced back into the carbs..(unless you live in Cali---LOL)..again this is just my opinion, and I am probably wrong...but I want to take a different approach to it, that is why I posted this.
If you are stock...or maybe with a few mods you may get the oil puke in your airbox too, and if you do...then my belief is that you need to modify just the single vent hose, as others have described what to do, and it is any easy fix too. I hope to be posting more on this subject, and I will, once I get into the internals of it.

Breathers ???

I'll be following your thread for other reasons. I'm a firm believer in an ounce of prevention is worth a pound of cure. I'm trying to prepare for the day I cross water that's deeper than antisapated. Say at least 2 feet deep. The intake should be safe , but what about everythig else ? Engine , CVT , differentials , fan blade , exhaust ? I know about Snorkle Kits . But could you suck water in elsewhere ?

I made an oil in the airbox video set. The first one describes the problem and the second shows how to use a Rhino siphon break on it. Drilling the head ALA FST is probably the best fix, but I did not want to do any drilling this time, so I modded the existing setup instead.

Thanks Chase,
Yes I've got your pics. and Mickey has told me about yours and xchamps, I REALLY appreciate you guys knowledge and input on this! I believe I am going to route mine thru the top of the roll cage, mine will be different.
That being said, I have already tapped into the head in the same place yours is....it is the perfect place, right where the chains will bring the oil back down, I love that spot and in fact...it is really the only spot a person should do it. I think I will probably have a box to hold the reservoir oil in a different spot. I am also going to use a rigid tubing....I think...got it set up, just ain't got pics yet...probably won't have until get carbs set in place....that is the only factor, on deciding how I am going to run or route it, haven't got my kit yet...Mickey must be sleeping-----just kidding. Looking at your pics, what did you put around the pipe where it enters the head...is it TIG welded?

I know this may not be what everyone else should do but this is what I did with my std bore kit venting issue.

I put a plug in the intake and took the hose and added about a foot more to it so I could route it inside of the bed and put a vented catch can in the bed.

The only time that it pukes any oil is when it is running WFO for a long period of time.

The fitting is JB Welded in. I would suggest making sure you have clearance between the stock carb linkage cover and the fitting you use.
