Removing clutch - piston stop or magneto holder?

I'm going to replace my shift shaft this week. Will a piston stop (screwed into the spark plug hole) allow me to remove the clutch or will I need to buy a magneto holder?
I know it will be apparant when I take it apart. I just want to have all the parts and tool there ready to go.

I think I just locked the countershaft by putting a hunk of oak in the rear sprocket. Or maybe I stuck a piece of aluminum bar stock in the gear teeth. I can't remember which method I used on which bike, but you get the idea.

I'm sure I can come up with something to keep it still. I didn't think the procedure was in the manual at the lot of the page but then I noticed the search feature and found it - lots of nice pictures. If I knew it was that easy I wouldn't have procrastinated this long.

I just used an impact wrench.

^ Ditto that. If you use the cram-something method, keep it as close to the clutch as possible eo minimise stress on parts you aren't dealing with. I've used a rag....Just let the rag get 'sucked into' the basket/case causing a bind that becomes the 'holder.' I don't like piston stops, but sometimes they are needed...Not for a clutch job though....Usually, an impact will take it off with nothing holding it. No need to load your crank/wrist-pin bearings/etc.

I tried the 'jam' method once. Ended up with a 45 tooth rear sprocket.
^Ditto the ditto. Pneumatic power man!!
Shift shaft should be a piece of cake! I've changed 'em on other bikes with a similar configuration to the KDX. Easy-peasy.
Pay attention to the springs!

As in?
A. Don't lose them.
B. Check their free length and replace if necessary.
C. Take the tension off of them in a criss cross pattern.
D. Pay attention to how they came out and put them back in the same way.
E. They are going to do something.
F. All of the above.
nG. Other.

Yes.
Well..'ceptin 'B'.
If you FIND them to be free..you'd better hook'm up to something!
That's an area that springs tend to slip out of place. At least according to the heartachey and sorrowful stories I've heard.
Probably more the kicker springs than the shifter springs.

...sheesh. A comedian!
