Fitment & Technical Details
Check piston-to-cylinder wall clearance and ring end-gaps inside the bore using feeler gauges prior to final installation. Lubricate the wrist pin, small-end bearing, and cylinder wall with fresh two-stroke injection oil. Install new circlips securely into the piston pin grooves, making sure they are fully seated before lowering the matched cylinder barrel over the piston assembly.Verification: Piston slides smoothly within the cylinder bore with correct factory clearance, and the complete top-end seats squarely onto the crankcase studs with zero binding or gasket leakage.
