Been debating on a blower for my Zforce 800 Trail. I will move the CVT intake outside of the machine like NMK has done and install a temp gauge. If it continually runs hot, having the snorkel tube in the bed will make it easier to install a blower fan.
As for temp gauges, the youtube video below compares the expensive Razorback infrared gauge to the inexpensive Trailtech. After watching the comparison, I will splurge on the Razorback. The Razorback infrared is true belt temp, and shows immediate temp changes. The Trailtech is like a regular thermometer, just measuring the ambient air, which is affected by airflow in the CVT case.
If not interested in technical details of the gauges in the video, skip to 5:00 in the video to see the actual temp gauge differences.
