Hey guys just looking for a little input. I have a 13 KX450F and it has the typical Kawi issue of getting pretty hot and I’m looking to try and get the temps as low as possible. Right now I have a silicone radiator Y hose kit that I got off of eBay that I’m looking to upgrade, a boyesen supercooler and I have engine ice in the system now. I’ve been looking for other recommendations that I can try to see if it will help. I am considering trying Evans Coolant. Has anyone tried this product and if so what was your outcome? Thanks in advance!

Water free coolant won't lower operating temps, it will just raise the temperature at which the engine starts to spew out coolant

I have a pro circuit cooler and i run that honda coolant thats in the blue bottle in my kx450. Works fine. Tbh the stock cooler worked fine too. This is all with a HC piston & race gas.

Evans coolant is the best in my opinion. I wrenched for Freddie Noren this summer and didn’t have any problems with it and thts what Honda recommends to run.
