Today I removed the drain with a cold engine and with a video camera for inspection I watched the smoke filter, everything is ok then I tried changing the oil 15w40 with a 10w40 oil and filter, I warmed up the engine and then with a long screwdriver I tried if the filter vibrated ... but anything all ok, I finally made a trip of 100 miles but I did not hear more noise, Baker!!!!Maybe when I put the bike on the side stand the oil goes on the left and interior noise you hear more, and when I put the motorcycle on the Centre stand the oil suppresses noise!!!!!?!?!?!?
