MZ/MuZ Riders

Hi all
I am having a problem with my silver star,when I start it up it takes quite a while to warm up,and is a bit "lumpy"on tickover almost stalling on occasion, when it is warm it seems to hesitate as you accelerate through the gears,ive changed the petrol,air filter,and cleaned/checked the carb...fitted a new plug........it feels like a jap 4 cylinder that is running on 3 cylinders,does anyone have any ideas as to what may be the problem.cheers steve

Check your choke is closing fully, and try charging your battery.

The symptoms of my bike were sometimes like when a 2-stroke engine 4-strokes.
