If your Suzuki GS500E is running rough or bogging down, those carb diaphragms might be shot. This kit gives you two replacement diaphragms to fix ‘em up. Fits the GS500E from 1989 to 2006. Unbranded, but it’s the right shape and size to get the job done. Brand new, ready to install. Don’t buy new carbs—just rebuild what you’ve got.
