Which bulb did you replace?  Front or rear?
Those LEDs are single filament bulbs.
They will only work in the front blinkers, not rear.
For rear you need dual filament.
If you replace them all you will need to add diodes to work w the single indicator on gauge.  (I get diodes from Sonrier at sparckmoto.com)

and as miller stated an electronic flasher. 

When do you expect to have the new diaphragms installed?

Well the bike has aftermarket turning signals, and they are all single filament. I plan on purchasing the electronic flasher from Sonrier, but if I don't have the gauge indicator I don't need the diodes right?

Will the electronic flasher work with the cb360? Or is there anything I would need? (I already updated the regulator/rectifier)

Also, diaphragm comes in today

If you have a stock type flasher the indicators won't flash unless you fit a load resistor.
Cheaper and easier to get relay suitable for LED.
Single LED may not work on front if it has double contacts for running lights?
You won't need diodes if you don't have warning light

The flasher he sells will plug right in.  If it still doesnt work w new flasher, swap the two wires on the flasher connectors.
No, if you dont have a gauge indicator you wont need any diodes.

BTW, are you only replacing the one diaphragm?  If so, I might think tuning the carbs could get a little wonky.
I wouldnt be surprised if the other diaphragm is soon to follow. 

A sure sign of a torn diaphragm is one white plug and the other dark.

I only replaced one diaphragm, I didn't want to order 2 because I wanted to know if this aftermarket one would work.

But, as usually, I noticed another problem   I put clear fuel lines on the bike, and I was going to warm the bike up before I did the carb sync, and saw that no fuel was going to the right carb. I took it out for a ride still, hoping something was just stuck, and after my ride fuel was in the tube, just none of it was going into the carb   is this going to require the carbs to rebuilt?

The float may be stuck closed.  Needing cleaned/cleared of debris.
Do you have inline filters?  I never had any luck w them.  I just count on the tap screens.  But my tank is pretty clean.
I also keep a small magnet in tap bowl to help catch any rusty particles.  It works well.

Well I did adjust the floats since they were about 6mm off. They werent stuck when I was adjusting them, could they have gotten stuck when I attached the bowl?

I'm having a hard time understanding where the fuel feeds from the tube into the carb, I dont see any paths from the fuel line.

And no, I  dont have inline filters. Fuel line goes straight from the pet cock to the carbs.

I've done a load of 360 carbs, 6mm seems a lot to adjust but I have seen tem with very low float levels. Are you set at 19mm or 21mm?

You said the line had no fuel in it when you started, but it was full when you got back?  That's normal.  The float doesn't open until you start to drain it while running.  If you have the lines off, or just installed them, then they'll stay empty until you use some fuel.  If no fuel was going into the carb, then the tube would never fill up.
