how do you remove the power valves on a 2001 ZR600efi, I took the 4 nuts off, but still something is holding the valve from coming out completely!?!?

look inside ,there is a stop plate held on with 2 allen head bolts. you have to take those out before the assembly will slide out

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
