Raptor 350 engine noise

Hello Raptor forum.

I recently bought a barn find in the form of a Yamaha Raptor 350 YFM, 2008. It has been stationary for 13-14 years, that is, since it was almost new. When I picked it up, the cover for the stator had been removed, on the side where the starter motor is located. Why, and dor how long this had been disassembled no one knows 🤷🏼‍♂️ - I have cleaned everything, lubricated everything, changed the oil and filter, new spark plug, new battery, etc. In addition, it was missing a carburetor, so I managed to do everything else before I found a Mikuni carburetor and therefore i didnt know if it would start.

I have found the carburator, and managed to start it up. After a while, it seem to find itself, It now starts first time, but there is a sound from the engine, and I fear the worst. It's just strange because it hasn't gone more than 1800km. There is a digital speedometer mounted, where this is counted.

Can anyone hear what the sound could be and have a qualified guess for fixing it before I disassemble everything?

I will leave a link for the video with noise here:


All the best!
