I'm sick of my p.o.s!!!!!!!

I'm so sick of my p.o.s. bike. Maybe someone can help me, but I think a live grenade is the only solution.

My bike is a $600 1986 Yamaha Radian 600. I ride it only to commute on (easy on gas). EVERY time I fill up, the bike runs like crap for a few minutes. It will run when opened up, but won't idle for crap, and feels like its flooding. Here is what I have done to fix the problem, but no dice:

Removed the tank and completely flushed it (less than one month ago).
Removed the petcock and cleaned and tested it (its vacuum operated off the first carb).
Checked the fuel filter (self installed filter).
Removed and completely disassembled the carbs, including removing all the jets, cleaning them; removing the float bowls and cleaning them; cleaning the needles; in other words the whole enchilada.
Synched the carbs.

My first guess would be that I'm stirring up some crap in the tank when I fill up, but flushing the tank should have remedied that issue.

I guess I'm venting more than looking for a solution. Does Goodwill take bikes?

I got the best solution for it... Set it on fire, and push it over a cliff. = Problem solved.

Then go buy a new bike.

check your spark plugs for wetness or dryness. also dump some fuel additives (STP stuff). those actually work.

What about where you are getting your gas? Water in the gas? I hope you flushed it with good n clean gas not water!!!

And even if there is stuff in the tank... the fuel filter should catch it and as long as that isn't clogged that wouldn't be the problem.

What about checking the jetting?

Pull the plugs and check them against this thread and its linky!

Used gas and carb cleaner to flush. I know it burns a little oil, so plugs do foul about once a year, but this crap has happened the last three fill ups (hi grade, Chevron, QT, or BP). Ride for a little bit, and it runs like a 20 year old champ.

Come on, talk me into a new bike. There's a Speed Triple that I've had my eye on for a while

If you're giving the bike away I'll come and take it off your hands!!! Anyway,you said it only happens when you fill it,right? Maybe your gascap vent is clogged and your gravity fed fuel pump is having trouble pulling gas against the vacuum when it's full but it gets easier as more air is in the tank. Try filling it and when it starts running bad open the gascap(if you have a second key,of course)and see if it clears up. How's that?

I'm going with gas tank not venting. You said yourself that if you ride for awhile it goes away. Makes sense, the fuel level would go down. If when you fill up you top it off the the very top try not to next time maybe just below the filler neck.

The Radian is a nice bike. You have to pull the plugs (keep them in order) to see if one or all the cylinders are running rich. One of the float needles may be leaking. You said you cleaned the jet needles, but did you take off the vacuum cover and clean the piston and wall? If the piston/needle doesn't move smoothly up and down, or sticks open or closed, the carb cannot run right.

And maybe try to not spin on the cap on too tight.

Are you getting vapor lock?

Or drill a hole in the top of the tank...
