It did not come with the CDI. It did not come with the carburetor. It did not come with the kickstart. I installed it on my 2004 Honda CRF 70 and it is amazing. The power is absolutely crazy. Good the clutch works great. It is a great motor. Make sure to drain the oil it comes with and to add the proper rating oil to it. It’s in the description but great motor. Highly recommend it. Yeah I’m missing parts but overall happy.
