i have been having problems with my 400ex. the electric start used to work great and never had a problem but throughout the span of about a month it started to dwindle down each day and now it doesnt even work. i can roll start it and it runs great but if i turn on the lights it seems to have no power and bogs down when i hit the throttle. i just put a new battery in it today hoping it would fix the problem but it didnt change anything. i dont know where to go from there so hopefully someone knows more than i do and can help me fix my issue. any input will help. Thanks!
