Thank you. Sorry i meant trx420fpm. Its a 420 rancher. I dont know if it has the angle sensor on it to be honest. It does have the fuel tank vent and it is clear. When i ride it i ride it fairly hard and have no problems with it. I let my daughter run it yesterday and thats when it started. She was just driving it around the yard. I did find the positive battery cable loose so itightened it up but it still stalled out after 5 minutes of her riding it
