The Road Demon Jr promises to be the ideal carburetor for budget-conscious enthusiasts needing a carburetor for performance upgrades for stock to mild performance levels.

The Road Demon Jr shares many of the basic design features of popular Road Demon and delivers crisp throttle response, easy tuning, great fuel economy and great performance.

These vacuum secondary carbs feature sight glass in bowls, two corner adjustability, adjustable primary jets, three vacuum ports, single inlet and tuning manual.  Choose size and manual or electric choke.

Installation Note:
