Hi all I bought an urban dz125 as a project but I cannot get it to start, there feels like decent compression, defo has fuel but struggles on spark after originally being fine. Previous owner knocked electrics so have been sorting those tonight( still some to do). Anyway when I try the kickstart the engine goes round there is a slight whooshing noise so I was wondering if best things to change dark plug and I think whoosh is from inlet manifold.

Anyone had similar problems or done up one of these bikes?!
