Currently I have only installed the Big 3 mods and speed limiter bypass. It runs like a raped ape. I have no issues on the MX tracks and other areas where I can really open it up. But, when just lightly cruzing around on tight trails when I stay between 1st and 2nd gear, the dang thing runs HOT! The temperature light comes on and I can hear the coolant boiling in the radiator.:wow: When I ride like this I've been in the habit of keeping a bottle of water on me to pour over the radiator. What else can I do? I've been considering intalling an external oil cooler.
