Hello,

I am restoring a DT125 and have picked up a spare engine. It has a serial number '12A'.... followed by numbers.

Does anyone know if this is a DT125 LC mk1?? or RD125 LC??

I own a DT125 LCII and the engine number begins '35A'.... but this does have the power valve blank...

Any response would be appreciated.

Thanks

According to my Haynes manual 12A is the restricted version of the RD125LC

Thank you... I guess this fits with the DT frame, but has a different front sprocket?

Much appreciated.
