everytime i start it it struggles i try to start it again it wont turn over again after 3 days it will start again but then do the same thing again when i open the throttle a little bit what would be causing that and after those three days it starts to leak gas nonstop i have no way of shuting the gas off on tank the shut off valve wont work on it so could that be flooding the motor causing it to shut off when i give it throttle i donĀ“t want to get rid of the motorcycle its in grate condition but i want to fix the problem on it so i can ride again please someone give me some ideas
