I’m not sure what cap it is but it isn’t the stock one it’s a temp gauge cap, I think the fans sound like a great idea as I may be in the top of 2nd and 3rd on these trails for the most part. The guy I bought it from had water in it but I’m going to switch over to engine ice. It has an upgraded pump as well (boyesen quick shot water pump) so hopefully with a little more speed and some engine ice I won’t be over heating on the trails. Thanks a lot for your replyWelcome to the site !!
I am guessing you are using a Trail Tech dash monitor or something ...... I am also guessing the bike does not have a Electric Fan ........ The issue is , you mentioned running around in 1st gear .... The problem with that is , these bikes are cooled by AIR flowing thru the radiators , so if you are going extremely slow , there is little if any air "flowing" thru the radiators , so yes it will run hot .... you can do some things to alter the actual temp , by adding a different coolant like Engine Ice (this requires a complete flush of all other liquids in the cooling system) , or Evans Waterless Coolant , Engine Ice claims to lower operating temps by 50 degrees (it is what I use) , if the bike is not puking coolant , then you are fine at the moment , if you are still concerned you can purchase a Trail Tech Fan system , it is all set up , and includes a Temp Gauge , and is easy to install
If you are going to ride mostly in 1st gear , or just do casual slow trail rides , I would highly recommend the fan kit , I installed a fan on my 450X and could not be happier , it literally will not overheat now , no matter how much I sit or go slow ... I built my kit from scratch and it is also thermostatically controlled , like the Trail Tech kit , so it will shut off when the temps are normal and turn on when you are going too slow for proper airflow across the radiators (it only mounts to the right radiator)
I would also replace the Radiator Cap with a 1.6 or 1.8 bar cap , the stock 1.1 will allow the engine to boil over easily , the higher pressure caps allow the engine temp to be higher without it spewing coolant , it will not allow it to get so hot things blow , just give you more working room , the engine will not be harmed by the higher temps of the higher bar caps ...
