These instructions for power valve disassembly were originally contributed to the gasgas community by Uwe Hale in the year 2000 or so. Uwe also created the first gasgas discussion forum "talking smack" for Jim Cook at Smackover Motorsports. So Uwe is the "grandfather" of the gasgas discussion forum.
