Have a 01 MC 800 with carbs that bogs and runs bad in the mid range. Can barely keep running at the mid range. Starts and idles fine and high r's runs fine. Started doing this at the very end of last year and did not look into this problem until a week ago (no snow around here). Cleaned carbs (they were really clean) and found nothing, checked reeds and they were fine and checked/cleaned and adjusted power valves. The valves were nasty dirty and sticky. Seem really good know. Still runs bad at mid range. Any help or suggestions? Thanks in advance. Todd
