Welcome aboard Kf8tc!!!
Get out your "cheaters" cuz you're gonna do LOTS and LOTS of reading about that gorgeous Nu2U beast.
You'll learn that the ethanol crap they're putting in our gas makes these carbs wanna puke, , thus carb issues are common and not a big issue (usually).
You'll also learn that Seafoam is your FRIEND.
Next time you fill up, mix about 1-2 oz of Seafoam per gallon of gas. For "in-town" driving try to keep your tach at about 2k rpm's. Higher rpm's will bypass your idle jets, and that's what we want to get clean. Hiway driving is normal, , , flow of traffic. Use the knurled knob (by the gas cap) to get your engine idle to about 800-900 rpm when warm. It won't fix your surge overnight, ,but it should smooth out and become a "non-issue" after about 3 tanks of gas.
In conclusion, as Bike&Dennis said, , ,use the search feature to find all the previous threads with your exact same "issue".
