Hi everyone. So I recently just brought a CBR250RR, I brought a new battery tried to start it but the motor won't start, it turns over. Dad and I looked in the carby and it's dried, we put petrol just the day before and not even a drop in the carby, apparently the bike has been sitting in a garage for 2-4 years without been turned on. We poured some petrol down the Inlet and it still didn't start. It backed fired once or twice, just today the motor started half a second. My Lights, Blinkers, break light etc turn on. I don't know what to do.
