I'm not a mechanic, but a clanking sound coming from the engine of a motorcycle can potentially indicate a problem that should be addressed. It's generally recommended to have any unusual noises checked by a qualified motorcycle mechanic or technician as soon as possible to prevent further damage and ensure your safety.
Clanking sounds from the engine could be caused by various issues, such as loose components, worn-out parts, or internal engine problems. Continuing to ride the motorcycle with a clanking sound could potentially worsen the problem and lead to more severe damage or even a breakdown.
It's always better to err on the side of caution when it comes to the safety of your motorcycle. I strongly recommend having a professional inspect and diagnose the issue to determine the exact cause of the clanking sound and provide appropriate repairs or maintenance.
