Svartpilen 200 strange engine noise around 4500 RPM anyone else?

[HuskyTorque]

Unusual sound coming from the right side of the Svartpilen 200 engine in third gear (cruising/slowing) at about 4500 RPM. It sounds like there is an imbalance within. Does anyone else hear this? At high revs, the engine is strong and smooth otherwise.

Even if it runs smooth at high revs, it is still worth getting checked

Is everything tightened as needed? Crash guards, skid plates, stuff like that? It could also be some chain slack, but that should be noticeable constantly, in most cases.

Might just be some resonance or something a bit loose. Worth a quick check on things like the chain, sprocket or even engine mounts.
