I purchased a quad with engine problems. The previous owner had pulled the motor and pulled the valve cover but decided to stop. I have done Arctic Cat top ends before but have never worked on the bottom end so any advise would be appreciated. What I have found so far is the connecting rod bearing is completely gone and some scoring on the jug walls. What i'm wondering is if anybody here has worked on these and if so did you replace all the bearings or just the ones that were for sure bad? Also is the 2006 Suzuki King Quad 700 motor exactly the same? It seems Suzuki parts are a lot cheaper to buy.
