Hi, I have bought a 2001 125 with a Walbro carb, whilst i was taking the carb off i noticed that the vacuum hose was attached to the manifold inlet but the other end was not attached to anything just dangling. I have read thru the Haynes manual and contacted my local Piaggio dealer and neither of them give any clues as to where it should be attached, i have checked the fuel tap and pump and all the hoses are attached so god knows where its supposed to go, can someone with a 125 have a look and try let me know where theirs goes!!
cheers
