Its an R1100S 2 spark 2003 model, I have suspected the battery for some time now and now its OK if you ride it every day but if you leave it for a week it will only just start the engine, Unfortunately my other problem is a dead ignition coil on the right cylinder [ stick coil on the end of the spark plug]. Minimum of 2 weeks ex- Germany, can't order one until Tuesday, I am on holiday for a week and all I can see is blue sky.

Thanks for the tip, I'm not sure if the 1200RT has the same coil but I know all the 1150 2 spark engines are the same as the 1100S 2 spark model, so I will defiantly ask the question, and your probably right about the extra suppresion for radio, but as long as it fits and makes a spark I'll be smiling. And as for the battery, well I'll just have to ride it every day!
