Title: Screw 884029 Intake manifold V7
Post by: JulienFlry on October 16, 2025, 12:39:36 PM

Hello guys,

I was working on my bike and I noticed a mysterious screw on both intake manifolds, part number 11 on the drawing, part 884029.
Does anyone know if this screw has any purpose?

thank you :)

Unscrew it and install a temporary hose barb for balancing vacuum throttle bodies.

Only if they are vestigial, because he's got a 1TB Heron Head model so there's nothing to balance.

Thank you guys, i assume then that they kept the same manifolds from the earlier 2tb models :)
