Doms CB550F1 project
Oddjob:
Look at the back of the arm, on the inside edge near where the cain adjusters are welded on there is a small vent hole drilled into the arm. Clean the hole as it normally gets partially blocked with rust flakes. A small straw or something similar inserted in hole and jiggled whilst shaking the arm will allow the rust to drop out

I thought there should be a venting hole, must have been powdercoated over, I'll have a look.

None on mine Ken, doesn't look like they've been painted over at there's no evidence. The most rattly but is the pressed bracing plate that has no vent hole either so I will just drill my own and flush it out
DomP:
All cb550 swingarms on Ebay are missing drainage/vent holes, would it be sensible to drill a 3-4mm hole so I can flush the crap out and put cavity wax in?
Oddjob:
The CB500 swinging arm certainly has them and it's essentially the same arm.
