The new 28XZ Truggy Engine perfectly balanced power for todays 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 thats incredibly smooth! And the 28XZ comes with all the components serious racers need for fine-tuning to meet any conditions: Two 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 for more head raising/lowering options and a piston sleeve that 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. Three needles enhance fine-tuning on the 21J slide-valve carb.
Comes with a high-performance P3 hot turbo plug
The Mark Pavidas Edition Tuned Pipe is the perfect accessory for the 28XZ; flywheel sets are required (sold separately) for certain truggy models.
