I have a 56 plate yamaha YBR 125 but over the last few days she has not wanted to fire. She sounds like she wants to fire but wont. Yesterday i managed to get her to fire but then she died on me and wouldnt fire, by the time i got home from work 4 hours later she started no problem. Today i went to start her and she wanted to as i could hear he trying but she wouldnt even fire. When i got home from work i tried again and no luck so i took the battery out and put it on charge just incase it was the battery, put the battery back in about half an hour ago but she still will not start. She sounds like she wants to start but wont fire. Has anyone got any idea what it could be. She gets used regularly only short journeys 4 miles a day, i just dont know what´s wrong with her any advice would be great.
