I decided yesterday that it was time for me to open the reedvalve cage and check their condition and to clean it as well while I'm at it. OK, so the first thing I noticed was that there was some sand sucked into the engine because of one of the gaskets which was not installed, the second thing I noticed was that there's a small nick at the tip of one of the reeds that appear as if it was burned out(approx 2mm longx 1mm deep) but the valve still appear to be closing. What could be the cause of this, imo it could be that the piston, rings or sleeves could be worn and that hot engine gasses pass into the reed chamber? So I will be ordering some booyesen reeds today, what's your opinion on them?
