Install was not too complicated but I didn't like the hose routing so I changed it and ran them down the right side behind the plastics. I have submitted photos for an update. Also I was not impressed by the heat output. I have a 15’ 900 w a firestorm can heater along with thermostat bypass adapter. Its hot enough that I wired in a switch for high and low. I've not had “cold” rides. The RS1 heater, with full windshield, small left wing window, and 42* temps I was cold riding. The heat did not seem as hot as my 900, nor as much air flow. Part of this may have to do with being in the front where the radiator normally is and taking on cold air as you drive. The heat ducts are not insulated so they act as a giant cooling tube to release heat. Even with 4 outlets 2 on the dash as defrosters and two down lower for feet or legs, I was not impressed. I will be finding ways to either upgrade, insulate, swap fans, maybe different hot coolant feed, whatever I have to do to get more output.

Done some more testing of the heater vs my 900 heater. This was done in the driveway, both machines side by side. Using a fluke ir thermometer.

190* dash
2600 rpm
128.8* heat
40* outside

174* dash
2100 rpms
150.4* heat
40* outside

These were max dash temps achieved sitting still with rpms up to generate heat and to keep coolant flowing. The heat temps were taken coming straight out of the heater vents w both heaters on High. This one does not have a high or low but I wired my 900 heater with one. Quite the difference in heating ability. RS1 had higher rpms for more coolant flow and 16* more heat generated but almost 21.6* less heat output. A total difference of 37.6* spread. So, as the first review states, I'll be looking to find ways for improvement or even a different heater setup all together.
