Near the end of a forty mile ride last Saturday my bike started running rich, since we wer almost back to the parking area where we started I didn't give it much thought. We have been out of town for a week for some r and r with plenty of time to think about what was wrong. It has been about 150 miles or so since I had the carb off so that's where I started, I found the main jet about half way out. Since I was planning to solder the jet and resize it was not a problem, the problem would have been if it fell out. I probably would've been working on it in the dark.
