do any companies make a coolant temperature gauge? 2468 - the Trail Tech Vapor has a coolant temp sensor that mounts inline in one of your radiator hoses - that's what I use on my street legal YZ I took my first street ride with my newly assembled YZ this weekend and according to the Vapor I was cruising around with a temp of 170-185 (outlet from the head to the left side radiator). I got stuck in some traffic and she went up to 240; after I started moving again she dropped back down (I would recommend the Vapor to everyone). After reading this thread and the other links I will be adding at least a catch can. My question is - the catch cans are obviously hooked to the spitter from the radiator cap neck. Where does the other tube coming off the can go? Is it a vent? How do you adjust the level in the can? Most catch cans on a car are above the radiator. How does it work when it's below the level of the cap? I'm asking because I'll probably make my own.
