Secondary air ?????

Hi Stu, thanks for the prompt reply, and thanks to Glenn for the emailed PDF. I read the info Glenn sent, and I'm confused still. My confusion lies in not understanding the function of the secondary air circuit (SAC), and that in the instructions MV sent me, there was no mention of the SAC. Perhaps, over time, MV realized a need for blanking part of the SAC.

Perhaps you or someone else can explain the role of the SAC I will better understand if I need to buy the two plugs Glenn's instruction sheet identified, and install them on my bike.

I can only add, that my bike, without the SAC blanked off between the air box and the SAC valve, runs GREAT!

Any thoughts?

Best wishes,
