Default HELP with 600f4 1999 wont run prop

Hello, i havent touched my 600f4 in prob 5 years or some +

I am goin to sell it, but i am having problems with the fuel supply.
When i am trying to start the bike, it is rough started, and its spitting out fuel. ( i reccon its from the carb)
It does start, but i have to have the "choke" and give it abit of throttle, but not to much... then it stalls

please take a look at the video

sounds like the bike's not getting fuel to all the cylinders. I'm likely gonna have to pull the carbs and clean the jets and bowl. If you've never done it, it's gonna be. It's difficult to pull the carb. Use a long pole as leverage to pry it up. Careful not to damage the boots. BTW, his much you asking for the bike?

A hair dryer works well to make the boots more pliable. It takes a bit but it's worth it.

Took the carb off, cleans the pilot jets. Two of them where fully plugged… hopefully it helps.

not sure.. but I live in Norway, so probably not very interesting?😅
