Hi, Dan here. I'm new to the site but I had the same issue. Bought my fzs600 last week and it would not open up past half throttle. If I eased off it would come up to speed eventually but if I went past half throttle it was like I'd hit a wall. Anyways today I pulled the carb out and noticed a rattle. After opening up the float bowls I noticed in 3of the 4 bowls all the jets had fallen out. I mean off completely. Surprised it's been moving at all. Anyway I put it all back together and took it for a spin. Revs all the way under load now. I'd say it still could do with the carbs balancing but the main issue is fixed.
