It is possible that if all or most the foam air filter was swallowed parts of it could be interfering with the powervalve operation even stuck in the crankcase itself,for the sake of 2 base gaskets I would certainly be having a look in and around the crankcase,barrel and powervalve area to ensure all of it has blown out and remove whats left before starting it again,
good luck with it all the best,

That had occurred to me as well. The air filter quite literally disintegrated into fine particulate matter. When I opened the airbox I thought the filter had been removed as there was no sign of it ever being there. It was when I noticed the sticky residue and thin ring of what was left that a deduced its demise. That and the black rings on the tips of the cans What little bit I could find just vaporized in my fingers so I doubt there was anything large enough to stick inside the motor. I'll have to investigate the power valves though, I don't know anything about them (this is my first two stroke).

Fortunately I have finally stumbled across the maintenance manual on this site so I'm a lot more comfortable tearing the carbs down. I've already got two bikes with carbs out, might as well add a third since the weather is finally getting nice around here

Thanks everyone.
