Model: Tm Racing Smr 125
Part: Engine

It will be possible to replace the piston of the TM Racing SMR 125 by loosening the screws that secure the engine block to its housing in the central lower part of the frame. Once the screws securing the supports have been loosened, the intake and exhaust manifold will need to be disconnected, and all connected cables must also be removed. Then, the screws securing the cylinder can be unscrewed in order to remove it and locate the corresponding piston: this must be freed from the connecting rod by removing the pin and the related circlip. After that, the new piston can be inserted and secured, ensuring that everything functions correctly.
