Stig,
Thank you for your kind and prompt response. My like 200i seems to be running well in terms of the factors which you described. I do wonder whether it's running a bit rich, since I observe sooty deposits on the muffler below the tip of the exhaust. Also, my fuel economy hovers in the low 60s mpg. These two elements cause me to wonder in turn whether the cylinder head temperature sensor might be intermittently working, (as the engine light [CELP?] illuminates intermittently), and the fuel injection system defaults to fixed settings to insure continued operation.
I would be content to ignore the engine light except for two considerations: First, I would not want for the light being on consistently to mask any other engine problems or warnings which might arise. Second, should I decide to sell the 200i, I would feel awkward telling the buyer that there's nothing to worry about. I believe that it would actually discourage prospective buyers. I would hesitate in their place.
I plan to closely inspect the sensor for solid connections when I perform the next valve adjustment. If said connections appear to be in good order, I will purchase a replacement sensor. Since Kymco Parts Monster is now Motosport Monster and no longer offers Kymco OEM parts, would you have a suggestion for where I should look?
Many thanks.
