Hi I have an o1 mxz-x, that I bought this last spring and have not been able to ride yet. It has weiseco pistons and v-force reeds, with an air box mod. I'm wondering how I know if I'm getting the right jetting. I looked at the pistons and the burn doesn't look very good "black" way to rich? The plugs are new so that doesn't help. Are there any guides or tools to help me get this to the proper setting? Sled starts right up, and will hesitate from idle to full throtle, I'm guessing bad, low octane gas, I did ad stabil, and I did fog it in the spring. And please somebody, let me know what the proper operating temp is for this sled. I have koso egt guages, but I'm not sure were to set them at. I'm about to head out on the 16th for my B-day and just want to make sure that I'm Good to Go.
