Honestly, a Nova Adam Drake, is a fantastic motor that you can buy for $200 or less. It has lots of power and it’s smooth. Match it with a Nova 9901 pipe and 41021 manifold ($100 or less) and it rivals higher end motors in performance, power delivery and reliability. Nova’s tune pretty easily and are consistent. Just follow proper break-in and maintenance of engine and clutch. The next time around, you’ll know if you’ll want to spend more for a new motor and matching pipe.
