I bought a completely rebuilt head and a balance shaft kit. A new piston is in shipment to me. The kit I bought for the balance shafts, doesn't contain much information on what to do. I was curious if anyone had a before and after picture by any chance. I searched but couldn't find one. Also, what are the balance shafts there for if we end up remvoing them anyway for this kit? Whats the point of having them there in the first place? What do they do in the first place, and what is this kit going to do differently to work better? Thanks guys
