My 81 xs650 has philips screws, not allens, as shown in the Tech section video.
I tried a #3 JIS screw driver. Next a #3 philips impact tool. and still no go.
Any thoughts on how to get the screws out?
 
"Impact tool" a hand impact or an impact wrench? A hand impact works much better here.
Just in case; the hand impact works best (wear a glove) if you preload the ramp (counter clockwise) with your hand then smack it with a (big and controlled beats small and fast) hammer.

Final try on the heads use a dremel cut off wheel so you can use a flat blade screw driver.
If all else fails you can drill the heads off, remove the clutch and the stems will thread out easily.
 
My impact tool is like the one kshansen shows in his link above.
a couple screw slots are getting a little boogered up, so I was trying not to beat on them too much. I'll see if I can find a vice grip tool to get on the heads.
 
You can reform somewhat boogered heads by taking the #3 bit out of the driver and smack it into the screw directly with a hammer, this force with no twisting helps get the bit in deep, then put the impact back on it and try again. Also try Tightening the screws with the impact, even though it's tightening once the screw moves a little bit it will move to loosen also.
 
Another trick; take an old hand grip and slip it on the impact wrench, improves your grip and lets you feel more comfortable with a rubber cushion between your hand and hammer head.
PS this is awesome on big cold chisels too!

One more suggestion on the boogered up screw heads.

Before using gggGary's idea take a small ballpean hammer and tap around the opening in the screw to somewhat close up the slots then take the bit that fits an undamaged head and tap it in to the one you just peaned closed. That many times will restore the screw head so the impact driver will then do it's job.
 
As Gary mentioned, there's a proper way to use one of those hand impacts. You have to turn it in the direction you're trying to go to take up all the "slack" or play in the tool, then smack it with the hammer.
 
Thanks for all the quick replies. I got them out.
I used a larger ball peen hammer and really whacked that impact tool hard.
Your suggestions of taking up the slack in the impact tool was a big help.
 
Yes, if you don't take up the slack in the tool, most of the hammer blow is just wasted.

Right-on 5T (EDITED) - and it is also essential that the tool be lubricated so that the ramps inside can slide smoothly without friction. I give mine a little squirt of oil every so often to keep things “slidey”.
