new scoot for cheap have a few questions

[tm4n6910]

bought this jonway 150 this week for 250.00
after we unloaded it , i took off for a test drive and it seemed pretty solid and scary fast for a scooter. after messing with it a little it seemed to be more than stock , po put a bbk on it , bigger carb and jetted it, perf exhaust and racing cdi and coil. i did oil change and plug and thought about taking belt cover off to check the belt. is there anything that could pop or fall out?
