This is a used engine assembly that has undergone a professional top-end refresh. While we have not heard it run since the rebuild, internal inspection revealed the barrel, piston, crank, and main bearings to be in very good condition. New gaskets were fitted during the rebuild, and it turns over with excellent compression. It is sold in ready-to-fit condition, ideal for a restoration project.

Description
Revitalise your Yamaha RD125LC 1GM YPVS Mk3 with this complete engine assembly. While we haven't heard it run, it has benefited from a thorough top-end refresh, with both the barrel interior and piston confirmed to be in excellent condition. The crank has been inspected, and con rod movement is well within limits, with no roughness detected from the main bearings. New gaskets were fitted during the top-end rebuild, ensuring a fresh seal. The engine turns over smoothly and exhibits impressive compression, suggesting it could be a straightforward 'plug in and run' unit for your motorcycle. All correct new nuts have been fitted to the top end for proper look and function, and the power valve is correctly in place under its cover. The engine number is *1GM-001778*, and it proudly bears the 'MADE IN JAPAN' casting, signifying its original manufacturing quality. The stator and flywheel are also included, but no testing of these has been conducted. The stator cover has a small chunk out of it, this can be seen in the pictures. The Exhaust studs are present and not broken.
