I recently purchased a 2007 Honda Rincon 680. The test drive was fine, no issues. The machine needed some love. I did a full tune up and it ran fine. Then the rain started. Still a bit cool in my neck of the woods, so I laid off of the driver's seat for a week. I jumped on the Rincon this morning with the intent of running any kinks out of the machine. It ran fine until it warmed up completely. When warm the machine would bog down and sputter then almost stall out. Occasionally, the Rincon would stall out. It would start right back up and would run fine at idle and for the first 5 seconds of acceleration. Then it would bog down again. I made it home and decided that the fuel filter must have plugged up. Had a similar incident with my Kawasaki. I was going to order a new fuel filter then on a whim, I went out and started the Rincon up. No issues. Revved the motor up and kept it at medium idle no issues. I am figuring that the issue has to do with the engine temp, but do not know where to start looking for the culprit. Has anyone had this issue?
