Yah, I know. Dead horse. Big stick. Healthy beating. yadda, yadda, yadda. I've just spent over an hour searching several posts from the last couple of years about what to do to properly uncork the XR 600. Most are pretty similar, but there is enough variation (maybe due to altitude and temperature?) between all the posts that there doesn't seem to be a single no-fail, for sure answer on what the best jetting is. I know that my bike is absolutely bone stock. I'm gonna put a Yosh full system on it in the next week or so, and I plan on evaluating the entire intake/exhaust tract. Never gotten inside the carb before, so I really don't know for sure what kind of jetting it currently has, but I will probably run a 68 pilot and 155 main, needle in either the 3rd or 4th position. We'll see how this works out. I intend to start messing with it in a few days, so I'll be resurrecting this thread from the dead on a regular basis as I have time to work on it. Does a 68pj and a 155mj sound about right for SoCal?
