I have been riding the vforce 700 for a few years now and just picked up a left over 06 anniversary raptor. I don't have but 5 min on the thing and have been reading about the front sprocket swap. The shop tells me I must change my chain if I swap the sprocket. Can someone help me out an confirm this. I have seen alot of chatter or people making the switch, but nothing about the chain. I will ride primarily sand with this one. Thanks in advance!
