The short answer is probably an obstruction in the line that feeds that right carburetor but, ,

More information would be helpful in order to give a decent "diagnosis" like, , ,

Did you do any work on the bike/fuel lines since you last started it?
When the bike didn't start, was there spark at the plugs?
How did you confirm there is fuel going to the left carburetor?
What did you see (or NOT see) that narrows the question to the right carb?


Its strange that the right carb gets no fuel, but the left one does, , , I can't recall ever reading anything about a problem like this.

Being almost impossible for the fuel line to either one to be plugged I would suspect the float valve is stuck closed or the screen on top of it is clogged.

I am with Dave. I know you do not want to hear this, but sounds like it is time to pull the carbs. I have done a total rebuild of the ones on my 88. These are the only things that I can think of also.

i had problems with fuel in one carb.had nothing to do with the float.....It was the bowl vent...Completly plugged.....
This was confirmed and fixed by compressed by disconnecting the crossover tube (bowl vent) and blowing air into each one...

A ycouple of things to try before pulling carbs.. Undo the fuel cap. That will let tank vent. If no good, find a piece of fuel pipe. Put a big syringe with no plunger in one end of line and hook other end up up to your carbs. Hang syringe higher than tank, and fill with fuel. This bypasses fuel pump and vacuum petcock. I had same symptoms of one carb empty on my cbr after standing. Above method got it running, and it's worked fine ever since. This could be my pump a bit weak, a common problem. Also, a quick hard tap with a screwdriver handle on side of carb bowl can release a stuck float which as others have mentioned, could be the cause, although they normally stick open letting too much fuel in. Try the gravity feed, think this will solve it ( I hope !)
