Coolster 125 wont start

[Mervfelton]

I have a coolster 125 atv that wont start. I put a brand new starter and starter solenoid on, the battery is 100% charged. After charging battery the stater did engage and crank the engine but once the bike died the starter wont engage any more, the solenoid just clickes and makes a buzzing type of noise. Pls any info would help!!
