Suddenly I got grinding noise coming out of the engine area of my Kenevo while spinning the crank, my first thought was it coming from inside the motor case, but after detailed examination and without battery mounted I saw that the chain guard was bend down and grinding the sproket.
After pulling up the chainguard the problem was fixed.
