Motor turns but no spark

[Bob_signy]

Hello,
About two years ago, my 2004 Suzuki gs500f stopped starting after letting it sit for 3 weeks in the summer. Unfortunately, I was unable to do too much troubleshooting as I was in the process of moving. After moving a few times and having a newborn child, I was unable to do much with the bike.

I now have time to work on the bike. I purchased a new battery after my old one of 5+ years. I am able to get the bike to turn over (engine), but not start. I have come close once or twice, but only for a second or two. I sprayed some starter fluid in the spark plug to see if that helped, and it did not. I also replaced the spark plugs 2 years ago during my initial but limited troubleshooting.


While taking the bike apart a few days ago, I noticed a few things:
-The tube going to the gas tank was broken off, and the opposite end towards the floor was clogged.
-The gas had a yellow color to it
-The airbreather was clogged
(See photos below for more visuals)

Before I start replacing things, could my issue be the two clogs? Or could it be something else? Any advice would be immensely helpful.

Thank you.

Clean the tank and unclog hoses, petocock ,drain and purge the carbs with fresh gas , if you are lucky, you won t need to clean carburetors.
if is starts roughly, clean carbs.
