I overfilled my engine oil level when changing the engine oil. The book says that this could cause a problem. I also turned the engine over with the plug leads disconnected until the oil light went off. I do this as a precautionary measure to ensure that thre is enough oil pressure before starting the bike. This is the second time I have done this and on both ocassions the bike has run perfectly but has a very erratic idling speed to the point that it sometimes cuts out. Please help if anyone out there has experienced this problem. Greatly appreciated. Clint
