Description:
This engine is a 1/8 on-road racing competition tuned engine produced by O.S.SPEED.
The manifold has been changed to the new MR05 manifold, and the combination of the O.S.SPEED R2106 combo set has been changed accordingly.
he MRO5 has a different length and angle from the previous model MR04, making it easier to adjust the carburetor in any power range.
