If you think your carbs need cleaning, try this first. Yamaha makes a product aptly called "Carburetor Cleaner"…comes in a large plastic bottle (not aerosol). I’ve had very good luck resurrecting dirty carbs WITHOUT disassembly using this product. When it works, this method saves time, effort and expense. Best of all, you don’t need new rubber components as you do when the carbs are taken apart.
