Another question as I'm new to motorcycles. I have 1980 cb650c hasn't been driven yet. Not running. The transmissions question: motor off...shifting into gears I can go neutral (wheels moves freely) 1st 2nd and 3rd I can hear and feel in the pedal it goes into gear ( have had a motorcycle before) but into fourth the pedal has full motion but seems dead. Like nothin is engaging. Is that normal? Cause bike is off or what's probable cause??
