The decompression valve on my Piaggio Si leaks, resulting in terrible acceleration, low topspeed and a whining sound from the cylinder. How do i take it apart so i can properly clean it? And should i buy some kind of sealant? Or should i just buy a new one?
I was an incredible idiot and opened the valve while i was going topspeed because someone told me it'd make loud explosions, which i of course wanted to try out.
