Frequently Asked Questions  

Do you make your breadbox to fit this carburettor?

The simple answer is that we only make our air intakes to suit the carburettors listed in that items options. We can make one off products to suit other carbs, but it is important to note that this is a custom job and added costs will occur.

 ​

Do I need carb support bracket when purchasing your breadbox or velocity stack?   

Yes. the air intakes that I offer do need a carb support bracket. If the carburettor is not supported the seal between the carb and the intake manifold may leak resulting in a lean running engine that can become damaged over time. For EVO motors and Twincam motors you can purchase the GASBOX carb support bracket through Razorback Motosupply found on the parts page.

Does my sportster / big twin need breather bolts? 

Earlier sportsters and big twins breathe directly from the crank case as apposed to newer Evo motors that breathe form the heads via the bolts that are used to secure the carb bracket in place. It's best to check the year of your motorcycle against an owners manual or consult a professional to make sure that you get the parts that are right for you. If you have an Evo motor that does use the head breathing system, these are required as installing solid bolts could result in severe engine failure.
