Throttle Body Screws

[pooh]

Hi folks
Can anybody tell me what the adjusting screws are on the side of the throttle bodies on my 2001 M900ie?

Are you asking what the purpose is?

[Starter Sprag]

They are the air bleed screws, used to adjust & balance CO mixture, 4-6%

[pooh]

Yes capo I am wondering if they only alter tickover mixture or across the range.

You use them to set CO mixture/balance at 1200 RPM

ie, slightly above idle

Thanks for that

Ian
