You can check the amount of blowby. Disconnect the hose at the airbox. Crank up the engine and feel for blowby. Rev the engine and check again. Mine was hardly noticable at 5K rpm. I'm sure there is more at 8-9K but nothing like a steady stream of gas with a heavy load of oil drops.

Agreed. To me, my guess is that this entire contraption (OCS flipped either way, hoses, clear drain tube, etc...) is due to EPA and the need to catch and burn any and all HC's.

They want what little vapor that comes out of there to be run back through the motor, via intake. That would be a noble concept if it actually worked as such. Instead, they had to attach a trap to catch the heavier stuff (OCS thingy).....just so the rider can dump it into the soil instead of letting a very minor amount of vapor escape into the atmosphere.

So, my choice was do I want to play the "dump the concentrated pollutants while no one's looking" game, or do I want to avoid running that vapor across any and all sensors that effect the run-ability of the bike because of the EFI?

I may end up putting a small filter on the end but again, that would just create a place for the vapor to condense and drip.

Just thoughts.........
