This is something I didn't think about until now. How does a BB331 kit affect your emissions? That with a Q4....

EFI bike

In Taiwan we're legally not supposed to change ANYTHING on the bike. In practice it doesn't come into play often...just when transferring title or emissions test. (Or when someone calls the police because of your loud motorcycle)

Putting the stock can back on is no problem, but will the 331 put out an extra amount of emissions that may fail the test? (A broad question not knowing the standards here I know...but just in a general sense. And I believe Taiwan uses EU emission standards)

I'm thinking I could use my electronic fuel controller to dial in the absolute most minimal fuel settings...just enough to keep the bike barely idling. Am I naive in thinking that would work? (Testing is done at a motorcycle shop. Guy won't care what I do as long as the bike is running at idle)

Anyone with any experience in this area? I know little about how emissions work.

LOL....

 

Har har.

 

In theory, the EFI should keep the emissions in spec.

Removing the stock muffler removes the catalytic converter (honeycomb catalyst) .... good luck passing any emissions test. The reason for the air suction valve is to keep exhaust temps high in order for the catalyst to work and keep emissions low. Not removing the air suction valve would cause an aftermarket exhaust to change color and cause premature wear of the packing material. With an aftermarket exhaust you also loose the O2 sensor that the EFI uses to regulate the mixture. That will result in a fault code. In many states/provinces in North America, vehicles can't go through emissions testing with a fault code.
