So today I figured out how to remove the carbs from the engine and took them apart. I took out the fuel jet and saw that the two left carbs were almost fully plugged up by crystal like substance (fuel?). So I cleaned them with carb cleaner, made sure all holes you can see through. I cleaned everything else I thought I needed to. Here is what I was looking at when I took out the bottom of the carb and the floats: So I sprayed all of that with carb cleaner, wiped it, blew compressed air inside all the holes. The only thing I unscrewed from there was the center jet (top pic), which was very dirty. Now, I put everything in again, turned the bike on, and it still does not idle. It works fine on choke. When I try to throttle a little, it dies. If I open the throttle it revs up. So idle to about 3.5K RPM can not be maintained. Have I missed somewhere to clean? Were there any other jets I was supposed to unscrew and clean out?

Thanks for all the advise. So far I have done the easiest thing, I sprayed down the throats of each carb the carb cleaner. The air valves now finally open (when I throttled before, only one would move while 3 would be stuck). So, it turns on with a choke and RPMs go as far as I want them to, revs nicely. While turned on, I sprayd a lot of carb cleaner in while opening and closing the throttle. Finally, it is alive, sort of. When I take choke off, it dies. Can't idle nor will turn on, even though the engine is hot, while choke is off. Is there a way to fix this without cleaning out all the carbs and having to take them off? Or am I still looking into removing carbs and cleaning them? I also need to change my filter and oil, about 4 years old!

Thank you in advance for any help you can provide. Here is my situation: I have a YZF 600R standing in my garage for over 3 years. It was working fine before and had no issues. Now, it only runs on chocke and will shut down if I open the throttle or turn the chocke off. Basically, can't ride it, barely idles. From what I read, most likely problem is of course the carbs and the old gasoline. So, I want to clean the carbs. How should I clean them? I took off the gas tank and took off the air filter. I'm staring at the carbs right now, now what? Please be aware that I'm rather new to working on my bike. For instance, I forgot about the gas shut off valve so when I disconnected the gas line from the pump, 3 gallons of old gas started spilling and I ended up stinking up the house. I'm not all thumbs, but would appreciate more of a step by step instruction. Thank you all again. - AlexZ
