so all the chains are shot in my 2004 650 v2. I understand that the Kawasaki prairie motor is the same. I have seen some aftermarket chains from KMC that are listed for the prairie but not the Cat 650 v2. How do I tell what will work. the engine SN is VF650AE55XXXX. Is there an aftermarket company that makes a kit for these 4 chains together? thanks so much in advance
