Hey guys I just bought a 2004 Vforce 700 a few days ago. I got a steal on it for $500. The guy had many atvs and did not want to deal with this one. The bike starts, runs and drives fine and just had the valves adjusted but the guy told me there is a wrist pin underneath the front cylinders piston that has a loose connection and play with the rod that connects to the crankshaft so its making a really loud knocking sound. Has anyone ever heard of this problem or could it be something else? How much will it cost to get fixed? Thanks alot and this is my first atv purchase so im really excited to get it out and cruising.
