Alright i have a 2011 trx420fm. It rides great for the first 10-15 minutes then suddenly sputters and dies. Its hard to start after and usually have to wait about 5 minutes before it will finally fire. Ive checked air filter and fuel pump and filter. Is there anything im missing? Also i noticed tonite that after it stalls i turn the key on and there is a slight ticking sound near the rear of the motor.
