Using the PVL ignition the amount of movement in the stator is irrelevant, the rotor does not use a key way so you could theoreticaly advance or retard the timing as much as you want, just pop the rotor and move it. Of course you need to use a timing gauge to find top dead center, then determine what you want for advance or retard, reinstall the rotor. that is actually kind of backwards to how you would set it but the combinations are endless.

Secondly, who knows what about a decompression system that fits into the plug hole on the head of the hundie? I just bought an '87 KX500 motor with one professionaly installed which was used as a flat tracker.
Do they work? Do they work well? Should I be looking at keeping it?

Thirdly, is the '86 and '87 motors the same, ie: If I have one of each, could I strip them down and use the best parts from each and build a good'n?

Lastly, what does a flywheel weight do? How do I get it done? Do I want it done? What are the downsides?

Cheers

Steve

Hey what's up, I am building a KX500 Su-Mo as well. Mine is a 1987 which is very similar to the 86. I'd like to hear about that decompression system, as my lightweight ass has a hard time starting this bike sometimes!  LOL

Dunno mate, the pic was in Doordies gallery so he might know a bit more about it.
