so we swap out my kids rmk 600 pick up a 97 700 cheep. then it blows a conecting rod bearing on the crank side/clutch side. so we tear it down. and it needs a rebuild. needs pistons(worn) then conecting rod bearing it done. so now its my kids sled. he dont ride the big hills. so what do i do? rebuild a 97 or try to find a motor(thats not easy to do)
