First off, the most important tool in removing and installing the
piston pin clips is a good pair of saftey glasses.
I use a small pair of pointed hemostats and a hooked metal pick.
A small pair of toothed tweezers works great also.
I never re-use the clips, always install new clips.
You may want to do this proceedure inside of a large clear ziploc
bag. that way if a clip does go flying, it will stay contained inside
of the bag. I've had quite a few go flying off and never found them.

+1 I use small needle nose plyers to remove them, but they are tiny and WILL fly off somewhere if you're not careful. I grab one end and rotate the pliers and they pop right out. Inside a plastic bag is not a bag idea.....

I always use the tip of a hobby knive under the clip with my thumb on the clip.

Just grab the part of the clip bent away from the piston, and do it on the side of the wristpin that is hollow. Grab the clip gently with those long skinny needle nose pliers and twist, it will come right out.

Now installing the new one is the trick. sometimes it goes right in, and sometimes you feel like you have 5 thumbs. I just place the non bent side of the clip inside the groove and gently, very gently, if you bend it up it's done, push around the clip until it pops into place, then go back with a tiny flat head and push on it to make sure it's fully seated in the groove.

He is changing clips in an old V-Spec... he has C-clips, not G-clips.

On one side of your piston you'll see a rectangular notch around the side of the wrist pin... use this side to get the first clip off. Rotate the C-clip until the opening of the C-clip is facing horizontally. I use a small flathead (size you'd find in an eye glass repair kit), which is easiest for me, and push the side of the clip inward while applying upwards pressure. You are just trying to unseat the clip from its bevel enough to work it off. Once one side is off you should be able to work the rest of the clip off. Push the wrist pin out from the outer side.

Now you need to decide if you want to replace the other clip. If there's no reason to, then leave it. Replace the con rod and put a new clip on the side you took out. If you want to replace it: with the wrist pin and con rod off you should be able to take a pick or small driver and pry under the edge of the other clip, forcing it up and off the bevel. This will be very tricky at first.

Replacing the clip is easiest part. I do it like RB link above, fitting in one side of the clip and working the other side of the clip in with my finger nail/skin. I find using tools on the clip to reinstall it may damage it... either bending it or over stressing it.

On the VZ's I use the Arrow Racing clips... they are G-clips which makes removing the clips much easier next go around.

Before you begin:
Rule #1 - Don't scratch the side of the piston!
Rule #2 - See Rule #1

You can use the g clip on the os. I usually replace the c clips with g clips for ease of use.
