Like the idea of supporting the airbox. The carbs are in rubbers, are you leaving the airbox hard mounted or add some rubbers later?
Hard mounted. Most bikes have the airbox hard mounted and a rather stiff rubber boot connecting it to the carbs. Not much vibration isolation happening, so I'm not worried about it. But the airbox and stuff connectors act as the rear support forthe carbs.Like the idea of supporting the airbox.

I'm not too worried about it. I had to mill a step onto the support piece so it's pretty well locked in it's position. It's sandwiched between the plate and the carb connector bracket.to constrain the side-to-side (roll axis) vibration, would it make sense to consider two points for the airbox support?
It is, but I get better with each piece. Fab is definitely a learn by doing thing.Whole lotta fab work there!
If you ever bring it down to the Quail show, I’ll come see itSo far it's all working together. The air filter is a tight fit, but it fits. I might see if I can angle the carbs up a little bit, that would open sa bit more room. There's about 1/4" between it and the oil tank atthe closest.View attachment 365243
Yes, the SOHC CB750 was dry sump. But the smaller SOHC fours, 350, 400, 500, 550 and 650 were all wet sump, despite looking similar.The honda CB750 have a dry sump? had no idea
Yep, if you zoom in under where the clutch goes you can see the feed and return ports.The honda CB750 have a dry sump? had no idea

Yep, 60% balance, 130hz, 60a, 15cfh argon, ck layzr tungsten. Only upgrade on the setup is a better more flexible hose for the torch.You did all that aluminum welding with that Protig 205?
