I have a 1987 Yamaha moto4 champ and I am looking for an air filter?

I do not see a K & N air filter available as a direct replacement. If you would like a custom clamp on design, you would need to submit measurents of the surrounding area where the filter would go, throat size of the carburetor etc..
