Hello everyone I recently just acquired a 02cb750.

I also own a 81 xs400 cafe racer and previously a 03 vtx1300 and 03 vt750 bober.

The bike idles great, ride pretty good. After about 30 minute burst it begins to stall and will die. I wait about an minute and it will run again then stall a few minutes later.

Im cleaning my pod filters, replacing fuel filter and line, and I'm going to check spark when I get home. I suspect the plugs or coil wires

Looking for guidance to stopping the stall.

You could have some crap in the float bowl. It settles to the bottom when not running, but start the start the bike up and it begins to stir up and eventually clog jets.
I would also check spark right when it dies. Pull the plugs and ground them against the cylinder head while hitting the start button.
 
I am back and here are my findings. If attachments are unable to be seen here is a description.
Fuel filter and lines, DIRTY
Spark plugs, mildly black, have spark, .030-.033 gap
Coils give spark
Float bowls, dirty fuel when drained(has particles)

Clean the tank (if needed), flush the lines, clean the bowls, clean the jets, then fire her up!
I am making new lines. Also a note. The tube that connects carb 2-3 appears to be leaking. Or maybe it's the new line I added. Is it common for the crossover fuel line to leak? A lot

The debris that I have shown were in the fuel tank. Not sure what or how they got in there.

The first photo is for reference. Is there a way to just to remove half of the carbs and replace those o rings on the fuel t connector?

Is it possible to blow the rings out from having to large of lines/ to much flow?
