boxer_ted Posted July 27, 2014 Share Posted July 27, 2014 Original post: xt125r bogging running rich. Update on the fault. It turns out that the set up was not overfueling but quite the opposite. A fuel starvation scenario sent me down a different thought route. The carb was ripped out again and the main jet and emulsifier tube removed. The emulsifier tube housing/channel revealed a small hole, linked to the the air intake duct and on closer inspection with a strong lamp, was not letting light through. More dirt was suspected, so the orifice was subject to a squirt with carb cleaner and a small strand of strong wire. Light was eventually detected thus some crud removed. The carb was reassembled and reinstalled and hey presto the bike now runs OK. Just need to find the sweet spot on the air/mixture screw as I fiddled with this during the fault finding process. So in summary, when you clean a carb, spend some time to inspect thoroughly and ensure that every orifice is perfectly clean. If I had spotted this earlier it would have saved me a lot of unnecessary work. Link to comment Share on other sites More sharing options...
