2001 Honda CR125 Big Bore Kit Used . This kit I do not know who built this kit . No Power Valves . Piston was seized . Will need new Piston - Rings and Bored . The Crank & Rod is by Hot Rods . Its a 144 Rod and has no up and down play and is like new . The Big Bore head has some damage as seen in the picture that should be able to be repaired . Also included is a stock head that could be machined . The piston that is damage is Wiseco stamped 447 . This is the history as I know . It was bought as part of an inventory buy . Buyer Pays Shipping , No Returns , Thanks ronn450
