3 allen heads, spray carb cleaner to loosen carbon so they pull out. Each cylinder has 2 valves that are split in half. They look like mini pistons. Be careful there isn't much holding them on, so dont drop them and get the order mixed up.
Be sure you start the engine to let it warm up before you tear in to this project. I just did my 01 600ZR EFI and had the valves on one cylinder stuck. I had to take off the cylinders, head etc, to get at the valves from below to get them out. I had to beat them out and used a bunch of carb cleaner during the process. if your cables move the valves as it sits you should be OK. Buy a wire wheel to clean the valves. this will clean the valves to look like they are brand new. Be sure to check the cable length
thanks for the info, just got the job done, one side came out ok, but the other side was a bitch!!! it was stuck big time! :angry: but after heating and one can of carb cleaner I got it out and cleaned...what a difference!!!! :lol: it feels like a new sled!
Thanks guys for the help!
