Carburetor, After-Market. Completely new tooling, not something that has been adapted to work on your CT70. Produced from high precision tooling to insure the same level of quality as the OEM item, back in the day. All of the pieces that were originally manufactured from brass are made in brass for this unit as well. If you are after a unit that is a plug and play unit for your original carb, you can not rebuild and restore your original carb unit for the price of this carb. Take a look at the detail in this unit, if you did not see the CHP logo, you would swear that this is an original Keihin Carb unit. Carb comes stock with a #60 Main and #35 Pilot
