JRPW Pro Upgrade Kit Clone NKA
Created for the racer with an existing engine lacking that extra bit of needed HP. Kit contains our 2020 “Attack Series” Head and carb, matched camshaft, timing key, and all needed gaskets. Cam and timing key selection is made based on your input. Like always, instruction and guidance are provided without charge. This package is built around the NKA rules set with the unported head.
