Well, I got my basket case CB400TI started. However, it's only firing out of the right cylinder. I've cleaned the carbs twice, set the float levels, and swapped the plugs and wires around. I'm getting good spark on both plugs.

Compression test? Valve adjustment? Any help is extremely appreciated.

Woops, sorry. 1979 CB400TI.

After idling a minute, is the left exhaust warm or cold?

Completely cold. And so is the air coming out of the pipe. The right side warms right up though.

Have you tried starter fluid in the non running side?

You sure your idle circuit in your carb is clear?

Is your valve clearance correct? Might as well check.

I'll go over it with a multimeter tomorrow and see where I'm at. Thanks for your help.

Take a can of carb and choke cleaner and spray around the carb on the side that's not firing and see if you get combustion. I had a similar problem and it turned out my dumb self didn't tighten the bolts on the carb boot. Ran fine after that. You could be sucking air in somewhere.

Brown/green: 94
Pink/green: 160
Blue/white: 82

Coil
Yellow/green: .6

Plug wires: 7.78

In your opinion, should I be looking a new stator? The coil and plugs are close to spec, but one of the stator readings was a little out.

These are the spec's you want. You can have a variance of @1 ohm from these.
Newest specs:
Pink to Green 129 Ohms Old was 135
Blue to White 84.2 Ohms Old was 85
Brown to Lt. Blue 203 Ohms Old was 207
New specs were obtained by testing 2 NOS stators, early version with the bullet connectors on the Blue & White connectors instead of the plastic plug in.
The old specs should be considered the maximum resistance readings and the new ones minimum resistance

Your coil is good. I would recheck the stator readings and if they don't match up to the numbers above then you need a stator

I spent a little more time with the bike today. I was able to get the left cylibder to fire by using some starter fluid, but it would sputter out almost immediately after. Would this indicate that it's a carburetor issue?

What was the result of rechecking the stator?

Blue/white is 90
Pink/green is 147
Brown/light blue is 191.

New stator needed, eh?

Do you have any tips for finding a new stator? Or one that is used but tested? My preliminary internet searches don't look too promising.

Any stator from 1978 thru 86 for the CB400T, CM400, CB450T, CM450 and CB450SC fits and works. The only difference is the Blue/White connector. Early versions used bullet type connectors and later uses a plastic plug with spade connectors.
New: Those are pretty rare to find, DSS had 6 but those are sold out. 31100-413-015 or 025
Rebuilt: There are shops rewinding the stators but to my knowledge the only one repairing the pickup coils is Rex's Speed Shop in the UK. I'm not positive if they are doing both of them yet so an email is in order to ask. Rex's Speed Shop - Sales 01580 880768
Used: I would ask each seller for the VOM reading on the 3 circuits and compare to spec.
