Guys, I learned my Vento's countershaft sprocket is worn and need to be replaced. I stopped by Yamaha dealership and asked about the sprocket. They don't have it but will order as soon as I pay the half ($13) and will get it by next week. I read Soud's thread "Zongshen Sierra 200GY-2 Countershaft Sprocket Replacement" but not sure if the Yamaha c. sprocket is the same as the PBI sprocket Spud used . I wonder if the Yamaha's sprocket will fit the Vento's countershaft.
