Hey guys, I sold my thumper and I have 2 complete gasket and ring kits for the yz 426. The kits include all three rings for the piston and the gaskets all the way around the motor, there are five gaskets including the $30 aluminun head gasket. These are all original yamaha parts and brand new. I think they will fit any 426 motor. I would like to sell or trade them for parts.(like bars and/or chain) I will sell/trade kits together or seperately. Individually each kit would cost over $80 from yamaha.
