O.S. .28XZ TRUGGY ENGINE, O.S. SPEED .12TZ SPEC II ENGINE AND LC4 PLUG
Perfectly balanced power for today’s truggies!
With input from top truggy drivers, O.S. has developed the ideal engine for these hybrid hot rods! The .28XZ produces more low-end torque, providing the rpm/torque balance that heavier truggies require. The result is power that’s incredibly smooth, for truggies more drivable than ever thought possible! The .28XZ comes with all the components serious racers need for fine-tuning to meet any conditions like, 2 carb inserts – a 9 mm blue for higher rpm applications and larger tracks, and an 8 mm red for smaller tracks that restrict air intake. An extra copper head shim is included for more head raising/lowering options. The piston sleeve boasts 6 ports for significantly increased power!
· The larger head aids in cooling and is a 2-piece construction with inner head button.
· A sealed front bearing and high-performance inner bearing are part of the new crankcase design.
· The high-performance con rod features oiled bushings while the three needles enhance fine-tuning on the 21J slide-valve carb.
· A high-performance P3 hot turbo plug is included.
· The Mark Pavidas Edition Tuned Pipe is the perfect accessory for the .28TZ. Flywheel sets are required (sold separately) for certain truggy models.
