Carburettor cleaner from Yamaha

Hello though I am not a motorad driver (I hope you can forgive me) but I need to get your help. I still have an old Mazda 626 of 88 with carburetor. The problem is that the carburetor so much mur a mix of oil and soot added is that I get rid of it with normal cleaner net. Now I’ve cleared that there should be a carburetor cleaner for motorcycles from Yamaha that gets rid of everything. The stupid is only that I don’t know where I get this cleaner from. Do you know?
