I have no pics to show you but I can guarantee you don't need that. Let me explain, it will take a few words. You have two bolts holding the muffler to the pipe, unscrew them and take it apart. If you hold the aluminium/kevlar body and pull on the metallic silencer, you open it. Then you find the muffler wool fitted around the metallic exhaust tube. The restrictor is at the entry of the tube.
Concerning the KOSO counter, its a little bit off-topic, but as I said before, it was showing wrong numbers, was totally erratic.
