So if a replacement engine has no serial number, would I have to tell the insurance company as it has now become more desirable for thieving scumbags ?
The replacement engine has a number followed by dash 02, i.e. xxxxxxxxxxxx-02. I assume the 02 is convention for engines supplied as one off units. So the new V5 has this number whereas the original V5 had no -2.
My previous bike had a complete engine change due to corrosion. New engine came with a nice slip of paper with the new number printed on it. Made updating the V5 simples
My bike has been fitted with a complete new engine, gearbox and clutch. The engine number is unique to the new engine and cast into the underside of one cylinder. I had to get the V5 updated with the new engine number. Now you have some facts.........oh, and it was replaced under warranty
So new engine/gearbox swingarm and final drive fitted and in answer to my own question, the engine came with a new number and a copy of the shipping label with number written on it.
Engine number stamped on.
Anybody know if the engine number can be "decoded" to give a manufacturing date ?
Also thanks to Allan Jeffries for doing the warranty claim and work very efficiently, even though I bought the bike privately.
