In the spirit of being methodical and *sure*, I decided to see if I could disable (without removing) the emissions
equipment and be able to detect a difference that each component had on performance.
First up was the Secondary Air System (SAS).
It's the long, lateral, rubber tube below the charcoal canister that connects to the aluminum canister that bolts on to the head just above the exhaust port. Together they inject fresh air into the exhaust port (between the exhaust valve and the header.)
So how to disable the SAS without removing it? Got it! Just plug ... or cap the dang thing. Easy-peesy.
Slap the gas tank back on a go for a short ride. Remember ... I'm only changing one thing at a time.
And EUREKA! NO MORE IRRITATING POPPING ON DE-ACCELERATION!!
Just smooth power up and down. Yes-s-s-s-s-s-sssssss....!
Love this thread! It has helped me a lot. Did a valve adjustment with ease following your guide
Got a question about the SAS. Without removing the SAS and solenoid valve, is it okay to just plug/cap the SAS and ride it for a couple hours? Would like to test the bike a bit before I remove them.
And yes, it is okay to just plug the SAS hose/filter.
The SAS assembly -- and the charcoal cannister and solenoid valve -- are two different emissions circuits, aren't connected, and have nothing to do with each other.
So test away, homie! E-Ticket
