Now the bike will not start.  She cranks but will not pop off.  I changed the plugs and checked the fuel connections, and they seem good. I was thinking of checking the air gap at the Hall effect / timing sensor, but I am otherwise stumped as to why the bike now will not fire... It sounds as though the ignition is just not firing as hear the fuel pump prime and those relays seem to be working... Any help would be greatly appreciated! Eric                Eric                      Did you pull a spark plug and check if it’s actually sparking or not?                      Stupid question but you didn’t accidentally knock off the handlebar switch did you?                         Vicki Many Thanks Vicki, I will double check Spark and make sure the kill switch is properly working.!
