Air-box Adapte |  Mikuni TM33 Carb 12mm ext. reducing 50mm to 49mm OD

 Air box adapter sleeve has been designed and manufactured for a good interference fit over the Mikuni carburetor Bellomouth.

The sleeve has a 50mm ID at the carburetor bellmouth with a 12mm extension reducing to 49mm OD for smaller air box insertion.

 This Mikuni 50mm ID air-box adapter is designed for use on our TM33-8012 carb, when fitting to Honda XR250 mechanical carb models and other motorcycles requiring a 12mm extension at 49mm diameter when wanting to use the standard OEM air-box. This adapter may require shortening for some applications where correct length sleeves are not available. The adapter is made from silver anodized aluminum with a 2mm wall thickness for strength and rigidity.

    This can and has been used on many custom applications.
