I'm new to nytros...have a rtx 121 stretched to a 144...riding in powder the other night the temp light went on stopped to cool off light on again and again and again and so on got home and googled over heat on nytro and found a commen problem so decided to make my own tunnel cooler made out of 3/4 copper hard tubing elbows and hangers and a heater hose off a polaris dragon took a total of 2 hours and a hole saw and torch to solder tubing together went out tonight rode in powder for a hour worked great and kept the tunnel clear. total cost about $60. a little crude in the workings but it is totally functional. will post pics later. Love to mod.
