Belt ????

Hi Guys, I have a 2013 850HO XP, 27 Grim Reapers QSC Clutch kit 1800 rpm engagement. At 1750 miles I changed out the stock belt to dayco # XTX2244 belt, now it seems to be real jumpy at very low speed but idles fine in gear with out creeping. does this sound normal for this belt or should I just go back to a stock Polaris belt? BTW the new belt only has 200 miles on it.
