This engine is perfect for smaller circuits where torque is important.

The new TL21B3-Pro utilizes an improved case design featuring additional stiffening ribs around the sleeve area to control expansion due to heat.

A new long stroke design, coupled with our race proven 3-port design provides the perfect blend of strong torque and aggressive top end. The B3-Pro features much of the same factory machining normally found in higher priced hand modified engines. This includes extensive casework improving the primary boost port as well as the transfer ports. Fuel flow is further improved on the sleeve by the teardrop machining of the transfer ports.

The new B3-Pro also features a series of crankshaft alterations and combustion chamber changes. These include a new fluted crankshaft with revised timing. New combustion chamber design and new 2-needle, aluminum bodied carburetor with heat insulating shielding and replaceable venturi. All topped off with our signature black CNC machined cooling head!
