    not sure if anyone can help me. My atv starts great when its cold or first start. Ride around high range runs fine.

    Run it low range on trails gets hot and starts real hard. Vapor locking? or throttle cable adjustment? im not sure.

    thanks for any help

    If i hook up the airflow sensor that hooks to the air box it revs way up when it gets hot. To a point where its hard to shift because its starting to engage the clutch. If i unplug the machine wont rev high but sometimes its hard to start????????? Not sure if there is another sensor?
