So, a friend of mine had this bike for years, never got it running, and then finally got a working one. His wife asked for garage floorspace back.
I rescued him from this bike and this bike from him. It's a 1977 Suzuki GS400.
The airbox was missing parts and the filter, and many metal bits were rusty. So I yanked it. In doing so I discovered that the rubbers attaching carbs to box have these airhorns sticking into the box. Velocity stacks. The airbox is very primitive, aside from that. A square thing of thin plastic.
I cleaned carbs and put the stacks on, but kept the box off. It actually runs pretty well. The carbs are Mikuni CV, don't know what series, but not that different in principle from the ones FJ uses.
So, might it be that just a length of tubing between pod and carb is the solution to pods without rejetting?
This is a video of it running after carb clean. Sounds fine to me.

Good to see the old girl start....

Not really a Suzuki fan but I do believe they make some really serious strong running very tough engines, one day I feel some sort of Suzuki will be knocking at my door, most likely a GS! Love seeing the oldies fire up and run! Good work, Cheers

I'm a Yamaha fan first and foremost.
The Suzuki, compared to a Yamaha of the same era (my wife has my old 79 XS400) is so much more cheaply built, it's kind of funny. Still, the engine is a sturdy twin, and with a little more cleanup this old girl will go a few more years.
I need to whip up a battery box, an air filtration setup of some kind, and get new forks and mufflers. Mufflers are rusted to hell and fork tubes are pitted.
So, I welded up a battery box and rigged intakes from plumbing fittings and tubes.
