Top end rebuild questions

[gasgasman]

In my experience, the sticking rings can be caused by ethanol blended fuel.

I did not know that. Either way, the engine definitely needed a rebuild.

Any help with my question about the power valve re-assembly?

[edited 2/7: I was mistaken about the lack of an index on the right side power valve shaft to position the mounting of the lever, there's only one way, at least on the 06 I just bolted back together. Basically you can't get the rotational orientation wrong. Just go in reverse of the dissambly advice linked below and use a little locktite blue on the retainer screws.]
See
http://www.gasgasrider.org/pv_disassembly_mattr.pdf which at least has dissassembly process, but indeed it does not state how to orrient the side power valves on re-assembly. (PDF covers 200-300, not 125 which is different design.)

BTW, I used PowerSeal in PA and they measured it all up and were able to do a light hone ($45), did not need replate tho they say GG cyls come kinda thin on the factory coating (it just takes 300s forever to wear out), thus saving me a good buck. The piston kit they matched up to the honed cyl was a Wiseco at $185. Only needed to get the pin brg from GG dealer. Happy with this outcome.

PS: I have a wicked big squish gap, 0.10-0.14" so I'll be going to RBD...
