I was having some issues with my 05 Yamaha yzf600r. The carb was flooding one of the cylinders so I ordered this set from eBay and it worked! Thanks, great product!
Note: you may need to use a little grease around the gasket to hold it in while your mounting the carb bowl back on. The gasket wants to slip off dry.
Solid product. Just like the picture and includes the jets that are most likely to be damaged if you have any problems with your carbs. I didn't end up replacing much but I did swap out the o-rings. The air filter was actually the primary problem with my bike. I really didn't need this kit for my bike but it is well packaged and the jet tips were protected with a little plastic cover. Get it if you need it.
Can't comment on the operation of the components once installed. Sorry
