Looking at a '94 883 to buy for my wife. When the engine is idling,the front cylinder is not firing very often. When the engine is shut down the front cyl. is not hot. I know it could be several things such as the plug,wiring,plug wire,coil and stator. Anything else? Does the stator control/time the fireing of the plugs? And if it may be the stator,how much do they cost? Thanks.
