This is a very quick spooling engine configuration and will require a quality expansion chamber as well as a fine tuned carburetor to get the full benefits of the internal timing. This engine can also see better results with an after market CDI system and the use of synthetic oil after break in. Comes as pictured and ready to ship with a quickness through USPS Priority mail with tracking. Shipping is included in the price.
