Buy a belt from hunterworks.com. Others have reported the hunter works belt fixes the problem you describe.

 

Make sure your clutches are clean, check the belt for glazing spots. A clutch kit can help this, or just give it more power starting off for full engagement.

 

Hunterworks has a video explaining this issue too.

 

I've had the same issue after I was stuck in snow and spun the wheels, glazing the belt. Change the belt and you will be fine.

 

Maybe. But OP has 8 posts too, so it may be him.

OP, if you are new to this, please be advised if you're trying to baby feather the thing it will be a bit grabby feeling to the newer driver. The idea is to not spend any time at sorta, but not really engaged. Please try applying power a little more quickly and you may find out it's just your technique. Plenty of new guys have posted this only to find out they expected it to work like a car. It's not and won't. It be smooth it needs a clear and diecisive transition from stopped to moving.

Of course if you do it wrong enough time you will indeed glaza teh belt, and then you get to replace it AND correct your technique.

 

Might be the helix. I switched to HunterWorks EBS Less helix and it solved jerkyness at low speed. Love it.

 

Go with the big bucks and install a Dura Clutch and never look back.

 

Also had this same problem. Loading and unloading in my enclosed trailer last winter---very tight maneuvering. Then it was all the time doing real slow maneuvering in low range. Changed the belt and now its smooth again. I dont use low range as much any more either. Dealer supplied and installed the new belt free of charge--I was impressed as was my wife. So THANK YOU M&M Performance Kelowna BC

 

My XPT does it bad in High gear put it in Low and it's way better
