I changed my battery, and my bike just clicks the solonoid and the junction box; if I hit the starter but if I jump the solonoid it will automatically start. What's the problem?
What voltage is your battery at after charging? Less than 12.4 and you need a new battery. It should normally be 12.6 or higher.
Did you check your solenoid? Undo the high current side of the solenoid and check for continuity when the starter button is pushed. It should be 0 ohms with button pushed and infinity the rest of the time.
Are your battery terminals polished and tightened?
