I am doing preventative maintenance on my 2001 600ZR APV valves and can not get one of them out. I am going to try Carb cleaner etc. any other ideas in lieu of pulling the head??

Also, how do I double check to be sure I put them in correctly after I am done cleaning them? most of you will know that I have the round APV valves with two ( 2) pieces. does the longer part of the valve go in toward the bottom of the cylinder? I just want to be sure they are installed correctly.

any body have pictures you can forward to me via e-mail?

thank you for your help.

i'm a little leary of spraying a lot of carb or brake cleaner around the cylinder. i dont think getting that in the cylinder would be good it will wash the oil off the cylinder/piston. if you need to i would put a couple of teasons on oil down the cylinder after your done. ive heard people warming the engines up then trying to pull them helps some.

Definately let the motor run and get it up to temp they will come out much easier.A bud put his in upsidedown and ruined a valve and piston.Do one at a time so you have a refarance.4 valves on that set-up 90 bucks a piece not pair, expencive mistake.

Thank you for all of your advice. I have a challenge going on with the valves as we speak. I can not get the right power valves out. A buddy is going to help me pull the jugs early next week, so I can push the valves out from the bottom.
