I know, think how much carbon could have been burned off by allowing that to be re-combusted instead of rerouted!! definitely not doing this mod !!

OK, I confused and not sure what's fake news and what's legit?

I don't water moisture in my cylinder heads either... I just want the appropriate air/fuel mixture and maximum spark to ignite it all!!

Oil and/or water in the combustion chamber just cant be good??!!

I'm totally surprised myself how much water or condensation this produces.

Ever see a car exhaust dripping water when the engine is cold? Every engine does this until up to operating temp.
The older guys will remember this, when guys used to run water and ethanol into high compression engines to stop it from detonating under load. So a little water in the chamber wont hurt anything. Although, oil in the chamber is another issue.

The stock air filter box on the Round 107 M8 has the rubber tube going through the back of it and then towards the throttle body. Does that opening in the box need to be closed of when installing an EBS?

I would think so? If the tube is re-routed or removed, any opening would allow unfiltered air into the throttle body. Maybe a small piece of duct tape that is heat resistant to close the hole?

I routed the head breathers into a catch can along with the hose from the Trask CheckM8. I drained the catch can today after a couple hundred miles of riding and this is what came out of the bike. The hose on the left is from the Trask CheckM8 and the hose on the right comes from the external breathers from the heads.
