    Cylinder 1 Misfire

    I went to start my 03 gpr with 167hrs on it and the rpms were gone. So i thought my pet tach was screwed up so i get to the bay and i start to go and my top speed was 35!!! I go back put new spark plugs and went again still 35!!! i sounded the whole time that one cylinder was not firing. The 2 and 3rd started just fine. What are the possible problems...... Spark Plug Cable, Injector, or what else? If anyone has any suggestions please help me!!!!

    You need to confirm some basics first. Does the spark plug fire when grounded in the wire ? Does the cylinder have compression ?

    I fixed th problem, the spark plug wire was loose and pulled out of the coil, now reinstalled and ready to ride.
