Breather Location when running K&N Pods

[ptegsotic]

A PCV (positive crankcase ventilation) cap is an automotive part, why would Home Despot sell them? Are you thinking PVC instead?

As for my question, never mind. I went on amazon and found they are far more generic than I realized. Pretty much any of them will work and solve my problem...

pvc cap is what I had referred to (2nd post)

(the cap inside diameter, is much larger than the breather tube outside diameter right? there's no 'capping' of tube ... the cap is just a receptacle the breather hose-end rests inside.)
incidentally, the one breather tube I have with the K & N filter on the end ... sits inside pvc cap with approx 1/4" gap all 'round. But I don't recall what size pvc cap I used. I could go measure if someone needed to know for whatever reason. (?)

I misread, was thinking PCV valve.

My KLR had a Mercedes Reed style PCV valve installed in the breather... allegedly to help with oil consumption. When I removed it after a couple of years of ownership (as there had been reports of them getting blocked & causing crankcase pressure) I learnt that it was snake oil.....

Maybe overkill but I put a 300ml catch can under the seat, it was $25 off Amazon and just fit.

This is good solution although the filter is not needed. Any oil will be caught in the can then run the catch can vent to where ever you please. I ran mine out the back end like old Yosh race bikes. Not much oil was ever in my catch can when I road raced it, street riding will not be much different. Hot rodders use small nice catch cans also

I have the long run breather tube terminating down next to the swingarm pivot.

It was summer 2020 and to commemorate the timing, I repurposed an 4oz hand sanitizer bottle. Drilled a 3/4” hole in the bottom of the bottle, ran the end of the breather hose into it, and the bottle hangs upside down. Drilled a hole for a piece of safety wire to keep the hose and bottle together, and then an extra few small holes around the top for atmosphere equalization.

I like it because it’s clear and I can see if anything is accumulating, water or oil. It only collects minor quantities of each. But when it does accumulate, I can just open the flip cap and drain it easily! I get a kick out of it.

for the record I hate hand sanitizer
