hey my friend , i dont want to argue with you . just tell me how much your asking for, if not ,YOU can put it in your F*****G a**!!!and just make sure you open them before!
Actually, 20w50 is not that good for a bike, are you sure it's not 10w50??? I use to use Suzuki oil myself but I use to use 10w40 in mine, I would never use 20w50, much to thick for cold starts.
