2001 426 Quit Running

It travels fully when start lever on bars in pulled in. I will be tearing into it this week, and wanted advice on what to look for. Exhaust valves?

You might want to read up on how to start one of these bikes, because if it turns over fine with that lever pulled but hits compression without it pulled, it sounds like it's all good.

When trying to restart, the kick lever only goes down 3/4 of the way on the power stroke. Ankle breaker....

I went off this statement, which makes it sound like the bike is working normally.
Compression builds up on kick until you cannot kick it, bleed compression off and it will kick through again....
Anyways - could be a number of things, big end bearings sometimes lock the conrod up if they are getting worn, usually, you need to rock the bike backwards in gear a bit to dislodge them.
Don't think it's a valve, if valves need shimming, you should be able to kick it over too easy, since they no longer seat properly, allowing the compression to bleed off out the unseated valve.
If timing skipped, or a valve broke, you could have a valve connecting with the piston on the upstroke, stopping the piston from further travel, but you should not be able to get past that any which way - the decompression lever would not make a difference.
If I'm misreading it that using the decompression lever allows it to turn over fully, then it is possible your bike skipped time or broke a valve.
could also be something as simple as a problem with the kickstarter mechanism, but I'm not sure how the decompression lever would allow it to continue through the stroke....
