Got a 1975 XS 650 with mikuni carbs that has been setting for 16 years. Rebuilt carbs but it is running WAY too rich. I live at 7000 ft and will be riding the bike from 5000 ft. to 100000 ft. when I go over mountain passes. Does anybody have a suggestion on what size main Jets I need. Seems to idle well and doesn't run too bad but bad stumble in mid range. I could experiment with different jets but just wondering if anybody has any ideas
