External Breather Filter

External Breather Filter
I’m running my external breather down to the bottom of the bike. Is it necessary to put a filter on the end of the hose? Does the crankcase pull air back in through the breather? I was running a catch can and it was just full of yellow gunk and water which I assume is just condensation mixed with oil vapors.

If you use a PCV type breather like Trask CheckM8, or make your own by retrofitting a PCV check valve into the existing crankcase cover, it won't suck air, moisture, and dirt into the sump. Without a check valve, it will when the pistons both go up. So a check valve is a must.
