Ignition or carb?

After winter ltd440(82) carb cleaning, riding throttle up one cylinder didnt run.I think its ignition cause if I use, replacing new ngk, diferent spark plugs, side of runing cylinder changes.What can it be wires,coil?Is it posible that ignition damages without riding?Sorry for my english:)

Just from garage, cleared that its charging, that is why spark is too weak for both cylinders when battery goes out.Is there some way to find out which detail is over,or wires, and is it possible to buy 82 ltd440 charging elements if I am in europe?

If you switch spark plugs and the other side runs, then the spark plug is bad.

Hi Tere, Nothing against any of the advice you are recieving here, but there is a very good group just for the KZtwins, specializing in the 440 and 400. You might want to check them out. The membership has many Europeans, a member might be close, to help out or to find parts.
