Thunder Mfg.'s adapters are designed for performance. We also strive to make our products easy to install and use. Note that when changing your airkit you must rejet your bike. If you have rejetted prior with a Dynojet jetkit you will not need to purchase a new jetkit, we will supply the main jets needed in your adapter.
