Doms CB550F1 project
Oddjob:
I'd do the hole where Honda put it on the 500 Dom, I'm using the same hole to fill both sides with Waxoyl after it's been powder coated, then allowing it to drain out afterwards just leaving the layer of wax behind. Do that every few years and it should outlast me

Any holes in frames or swingarms are often there to allow the escape of hot gasses during welding. It reduces distortion I believe.

Rickman put holes in their frames for the same reason Garath. It was also to allow the nickel solution to drain during the plating process otherwise the frame would rot from the inside out.
Oddjob:
The problem though is that the swinging arm, because Honda didn't use seam welding but spot welding which allows moisture to form inside the tubes, this then rusts the tubes from the inside out, hence why you can hear rust flakes tinkling around inside, the holes allow you to get rid of those and also to put something down the tubes to stop any future rot.
Laverda Dave:
Did Honda put holes in all their frames Ken because I haven't seen any on the 400 frame or was it just the 500/550’s?
