Idles fine (except for 3 second idle hang). After riding it will settle at 1,800 RPMS. If I shut it off and restart, it will stick at 1,500 RPMS. Normal? The real issue I have is if you blip the throttle from idle, there is a millisecond bog (not a miss or hesitation, just a bog). Runs fine after that at low, middle and high RPM. Pulls to 8,500 and then sticks there or falls back to 8,300. Everything is stock. Was thinking of running some Seafoam into it. What else should I do as the sled is 3 hours from me so I cannot get into the carbs until after the season?
