Interactive exhaust valve

[Pterodactyl_imp]

Can anyone find and post a dyno run of the IEV-equipped bike?

I can't provide one cause I've changed to Staintune. When the OEM was on I put the IEV (thanks, you've given me another acronym to put in the quiver) to open and ran the engine. There was no real difference, to the ear at least, in sound level. Without a dyno a torque comparison is difficult. I am still struggling with Honda fitting these to Aussie '10 models and then dispensing with them if they were effective. The valve doesn't seem to be associated with emission control so why? Next visit to the dealer I will have a chat with the service manager. Maybe he can shine some light on the subject.

If any of the other Aussies on this forum get their CB dynoed then they may pass it on. However most would probably get the dyno done after mods and compare to the book figures, I guess.

Cheers
