sorry for my english but I can't write german. i do speak and read it so feel free to answer in german if needed. I have an urgent exhaust problem. I have mounted a pinasco cylinder, crank, cp carb etc. I bought the adapter for the exhaust that sip sells and I bought a sip road for px. For the adapter it says it makes every px exhaust fit. Now guess what, the exhaust doesnt fit. What am I doing wrong, or is it another sip road i need? all tips are welcome
