Does anyone know what sort of mark identifies TDC on a 98 SR125, please? I have removed the two round covers from the left side of the crankcase and I can rotate the rotor. There's no 'T' obvious on the rim of the rotor, as described in the Haynes manual, only something more like 'H-'. I need to find TDC to check the valve clearances.

Any advice welcome.

Hi

you also need to find the correct TDC 4 stroke motor means 2 TDC's best thing to do is to remove the valve covers & turn the engine over to the point that both valves are closed (clearance on both valves). The 2 | | marks (close together) are the igniton advance marks (which are close to TDC). When you have the valves in this position just adjust them to the spec
