Hi, new to the forum and recently acquired a tidy 03 1150gsa. Firstly what a motor, last bm was an 1150rt but this baby blows it out of the water. Recently developed a hesitancy at high speed and a rough idling, having searched this forum for information diagnosed the faulty coils, replaced with new coil pack and boy what a difference. Smooth idle and smooth power throughout the whole range. Fantastic forum with an abundance of knowledge and expertise which certainly gives me the confidence to tackle most servicing aspects. Looking forward to many hours/miles on my new machine.
