K&N Breather Oil Pros & Cons
«
on:
July 19, 2008, 02:58:08 PM »
Did some research and spoke with some people. As well as the very informative thread on TOB that i can no longer find, but there seems to be a con to installing the K&N crank case breather. Aside from the oil issue, is there anything you guys know about how someone would go about properly removing the crank case breather box and replacing it with somethign smaller? I need to do this so i can put a new shock in. I remember there was an issue with the size of the breather box affecting the performance of the bike and the K&N filter would lead to a lack of ready voulme there.
Any comments on the mod?

There are some advantages to pulling a vacuum in the crankcase, which the stock set-up does to a degree. I was told at a BCM maintenance seminar that in our motors, the difference in negligible.

Some say that the airflow into the airbox helps pull the dirty air out of the crankcase.
Others say its crap.
My Tube into the airbox cracked off, so I capped it, and removed the tube but still have my reservoirs (cheap) Probably the same as a filter on top at that point and no problems.
I would think that a filter would best be served higher in the frame like some have, compared to right at the breather. IMO

nice post count He Man. And that back tire is looking a little rough El Matador. Ive ridden with a blown rear tire, actually kinda fun.
I see no reason a breather filter would hurt, even if intake did draw a little of the blow by gas out, you would never feel the difference.
All racebikes run the breather up and into a catch can, for oil spillage. If there were a gain to be had, the racers would Be doing it.

I tried this on my SS years ago. Eventually the filter turns black, and blowback oil seepage will start to be a problem. I finally decided I didn't like the look and put the stock system back. YMMV (Your Mods May Vary)

AHH IM THE DEVIL AHHH! =D
In that case, then im going for that mod. My friend did the crankcase breather mod just like El Matador's setup and his bike has blowby gas spitting out the side of his bike and you can see all this vapor at night time, it looks like a radiator blew up on a car. But he didnt run a tube back to the airbox to suck that gas back in. Im gonna go to home depot tonight to pick up some tubing and rerun mine tonight. Any idea what size/type tubing i should get?

I did the TPO swap, and then rode to work the next day. I have to say that it did run a little funny especially at low speed. She just kept farting. When I got home, I did some searches,and found that alot of the big boys(of knowledge) say that they keep their stock breather and plumbling. I then put all of the tubes back on and have to say that I can definately notice a difference for the better. Maybe I'm crazy. Maybe it's because I have not done the ECU airfilter and pipes. I just know she runs better.
